System Power-On Methods Power-on Switch - see “Starting the System Unit” on page 2-1. SP Menu power-on request You can request a power-on via the Service Processor menus from either a local or remote terminal. If a remote terminal is to be used, the modem must be connected to serial port 1, and the operating system set up to enable a TTY login session on that port.
Follow-up to a Failed Boot Attempt The Service Processor will initiate a power-on sequence upon detection of a failed boot attempt. Service Processor Reboot/Restart Recovery Reboot describes bringing the system hardware back up from scratch, for example, from a system reset or power on. The boot process ends when control passes to the operating system process. Restart describes activating the operating system after the system hardware reinitialized. Restart must follow a successful reboot.
Use OS-Defined restart policy:: The Use OS-Defined restart policy default setting is YES. This causes the SP to refer to the OS Automatic Restart Policy setting and take action, the same action the OS would take if it could have responded to the problem causing the restart. When this setting is NO, or if the OS did not set a policy, the Service Processor refers to Enable supplemental restart policy for its action. Enable Supplemental Restart Policy:: The default setting is NO.
Service Processor System Monitoring - Surveillance Surveillance is a function in which the Service Processor monitors the system, and the system monitors the Service Processor. This monitoring is accomplished by periodic samplings called heartbeats. Surveillance is available during two phases: 1. System firmware bringup (automatic) 2. Operating system runtime (optional) System Firmware Surveillance: Provides the Service Processor with a means to detect boot failures while the system firmware is running.
3. Surveillance delay This is the length of time, in minutes, for the Service Processor to wait from when the operating system is started to when the first heartbeat is expected. Surveillance will take effect immediately after setting the parameters from the Service Processor menus.
Console Mirroring Console mirroring allows a person on a local ASCII terminal to monitor the Service Processor activities of a remote user. Console mirroring ends when the Service Processor releases control of the serial ports to the system firmware. System Configuration: Service Processor Modem connected to one serial port and enabled for incoming calls Local ASCII terminal connected to the other serial port.
Service Processor Firmware Updates The Service Processor EPROM may need to be updated for two different reasons: 1. The UPDATE (composite) portion of the EPROM has become corrupted. 2. The Service Processor firmware upgrades, without any corruption present. The use of a Flash EPROM allows updates to occur without physically replacing the memory. The firmware in your server can be updated using one of four available initiation processes: 1. Service Processor initiation 2. SMS Utilities initiation 3.
Refer to the downloaded update instructions, or to the System Management Services “Config” on page 4-4 or “Display Configuration” on page 4-25 or Service Processor menus on page 3-7, to determine the level of the system unit or service processor flash. Updating Firmware from the Service Processor Menus: The Service Processor Menus are available while the server is powered off.
Updating Firmware from AIX You must delete the file /var/update_flash_image before proceeding. The flash update image file must have already been placed in the /var file system. This could have been done with a file transfer from another server or with the dosread command of the AIX DOS Utilities. For example, with the flash update image in place, issuing the following AIX command shutdown -u /var/\filename\.img initiates the update process. Where *filename* is the name of the flash update image.
System POST Errors: If POST (Power-On Self Test) errors occur during start-up, this error log helps isolate faults when used with the diagnostics.
Chapter 4. System Management Services The System Management Services provides a way to view information about your computer and perform tasks such as setting passwords and changing device configurations. If you are using a graphical display as your system console, use the Graphical System Management Services below. If you are using an ASCII display as your system console, see “Text-Based System Management Services” on page 4-24.
The System Management Services screen contains the following choices. Config: Enables you to view your system configuration.
Utilities: Enables you to set and remove passwords, enable the unattended start mode, set and view the addresses of your system's SCSI controllers, select the active console, view or clear the error log, and update your system firmware.

Chapter 5. Installing Options This chapter provides instructions to help you add options to your CPU Drawer. Some option-removal instructions are provided, in case you need to remove one option to install another. If you have several internal options to install, these instructions enable you to add them all at one time. Before you start, be sure you are familiar with the safety and handling guidelines in “Safety Considerations” on page 5-2, and “Handling Static-Sensitive Devices” on page 5-3.
Safety Considerations Observe the following safety precautions any time you work with this system unit. DANGER An electrical outlet that is not correctly wired could place hazardous voltage on metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.
Handling Static-Sensitive Devices Attention: Adapters, planars, diskette drives, and disk drives are sensitive to static electricity discharge. These devices are wrapped in antistatic bags, as shown in the illustration below, to prevent this damage. Take the following precautions: If you have an antistatic wrist strap available, use it while handling the device. Do not remove the device from the antistatic bag until you are ready to install the device in the system unit.
Expansion Bays Your system comes with one 3.5-inch, 1.44MB diskette drive and a SCSI CD-ROM drive. All models come with one or more SCSI-2 disk drives. The capacity of the disk drives varies, depending on your configuration. The number of additional preinstalled disk drives in banks C and D of your CPU Drawer varies according to the quantity you ordered. D6 D5 B2 B1 D4 disc D3 A2 A1 D2 c D D1 C1 C2C3 C4 C5 C6 Your system's special design gives you the flexibility to use up to twelve 3.
Preinstallation Steps (All Bays) Note: All internal drives in this system are mounted horizontally. Attention: Caution should be used when handling all hard drives. Drives are most likely to be damaged during installation and service. Bumping or handling drives roughly causes latent failures. Do not stack drives and always use appropriate ESD practices. A drop of as little as 1/4 inch can cause latent failures.
Installing Disk Drives into the Hot-Swap Bays This procedure describes how to install a disk drive into a hot-swap bay while the CPU Drawer is powered on. Attention: Do not open the drive; no user adjustments or serviceable parts are inside. Note: SCSI disk drives and SSA disk drives are not interchangeable. Banks C and D support hot-swappable disk drives only. This procedure is similar to any hot-swappable disk drive that is supported by this drawer.
This section gives the instructions for installing hot-swap disk drives into banks C and D. 1. If the rack unit has a front door, open it. 2. Loosen the retained screws that hold the disk drive cover to the drawer and remove the disk drive cover from the drawer, storing it in a safe place. 3. Each hot-swap disk drive you plan to install must have the hot-swap disk drive carrier attached.
4. If you are installing drives in bank D for the first time, you must install a backplane in bank D before you can install drives. Contact your hardware support center to install the backplane. 5. It is recommended that you install the hot-swap disk drive in the next unused position of bank C or D, going from bottom to top. Attention: Attaching SCSI address jumpers on the hot- swap disk drive rather than using the automatic ID furnished by the backplane is not advised.
c. Align the side of the carrier with the raised guides on the left of the bay. d. Slide the carrier into the bay gently to keep from damaging the hot-swap disk drive. Slide the carrier to the rear of the bay until it is seated into the connector. Chapter 5.
e. Move the carrier latch to the locked position. If the carrier does not lock, check that the drive carrier is fully seated in the backplane. When the drive carrier is fully seated, the green LED on the drive carrier illuminates. SCSI Disk Drives The following table explains the meaning of the green and amber status LEDs and spin down button on a SCSI disk drive.
SSA Disk Drives Check Ready Power Locked Position The following table explains the meaning of the Power, Ready and Check status LEDs on an SSA disk drive. Status LEDs LED Status Definition Power On Power On Off Power Off On Both SSA connections good and drive is ready Blinking Only one SSA connection good Flickering Drive is executing a command On Disk drive failure Ready Check Self-test running Drive in service mode Blinking Disk drive selected 6.
Removing Disk Drives from the Hot-Swap Bays This procedure describes how to remove hot-swap disk drives from a hot-swap bay while the CPU Drawer is powered on. If you remove a hot-swap disk drive when the CPU Drawer power is off, steps 3 on page 5-13 and 4 on page 5-14 do not apply. Attention: Follow all procedures for ESD-sensitive parts while performing these procedures. For ESD information, see “Handling Static-Sensitive Devices” on page 5-3. 1. If the rack unit has a front door, open it.
2. Loosen the retaining screws that hold the disk drive cover to the drawer and remove the disk drive cover from the drawer, storing it in a safe place. Attention: Physically removing a hot-swap drive from the CPU Drawer before it has been removed from the system configuration may cause unrecoverable data corruption. 3. Verify that the device has been removed from the system configuration; the yellow LED on the hot-swap disk drive should be off. Chapter 5.
4. For SCSI disk drives, press the spin-down button on the hot-swap disk drive; observe the green flashing LED. 5. Unlock the drive by turning the carrier latch 90 degrees clockwise to the open position. SCSI Disk Drives SSA Disk Drives Check Ready Power Locked Position Attention: SSA backplanes must be fully populated. Each backplane connector must have a disk drive or a blank carrier installed at all times.
6. Disconnect the drive from the connector on the backplane by grasping the handle on the drive tray and carefully pulling the drive out of the server. Store the drive in a safe place. Attention: Handle the disk drive with care as it is very fragile and can be easily damaged if exposed to shock, ESD, or rough handling. 7. If you are removing another disk drive, return to “Installing Disk Drives into the Hot-Swap Bays” on page 5-6. 8.

Chapter 6. Using the Online and Standalone Diagnostics Diagnostic Sources The diagnostics consist of Standalone Diagnostics and Online Diagnostics. Standalone Diagnostics are packaged on removable media. They must be booted or mounted before they can be run. If booted, they have no access to the AIX Error Log or the AIX Configuration Data. However, if mounted, they have access to the AIX Error Log and the AIX Configuration Data. Online Diagnostics, when installed, reside with AIX in the file system.
Undefined Terminal Types If an undefined terminal type from the DEFINE TERMINAL option menu is entered, the menu prompts the user to enter a valid terminal type, and the menu is redisplayed until either a valid type is entered or the user exits the DEFINE TERMINAL option.
set up to boot from a server, the diagnostics are run in the same manner as they are from disk. If the diagnostics are loaded from disk or a server, you must shutdown the AIX operating system before turning the system unit off to prevent possible damage to disk data. This is done in one of two ways: – If the diagnostics were loaded in standalone mode, press the F3 key until DIAGNOSTIC OPERATING INSTRUCTIONS displays; then press the F3 key again to shutdown the AIX operating system.
General Attributes Always Required The following general attributes are the default settings for the diagnostics. Be sure your terminal is set to these attributes. Note: These attributes should be set before the diagnostics are loaded. Refer to the following table. General Setup Attributes 3151 /11/31/41 Settings 3151 /51/61 Settings 3161/3164 Settings Description Machine mode 3151 3151 PC 3161 or 3164 The diagnostics are set to emulate use of the 3161 ASCII Display Terminal.

Word length (bits) 8 8 8 Selects eight bits as a data word length (byte).
Online Diagnostics Modes of Operation The Online Diagnostics can be run in three modes: Service Mode Concurrent Mode Maintenance Mode Service Mode Service mode provides the most complete checkout of the system resources. This mode also requires that no other programs be running on the system. All system resources except the SCSI adapter, and the disk drives used for paging can be tested. However, note that the memory and processor are only tested during POST.
Note: Pressing the F3 key (from a defined terminal) produces a "Confirm Exit" popup menu which offers two options: continuing with the shutdown by pressing F3; or returning to diagnostics by pressing Enter. For undefined terminals, pressing 99 produces a full screen menu which offers two options: continuing with the shutdown by pressing 99 and then Enter; or returning to diagnostics by pressing Enter.
The diag command loads the diagnostic controller and displays the Online Diagnostic menus. Running the Online Diagnostics in Concurrent Mode To run Online Diagnostics in concurrent mode, take the following steps: 1. Log on to the AIX operating system as root or superuser. 2. Enter the diag command. 3. When the DIAGNOSTIC OPERATING INSTRUCTIONS are displayed, follow the instructions to check out the desired resources. 4.
4. When a message indicates the system is in maintenance mode, enter the diag command. Note: It may be necessary to set TERM type again. 5. When DIAGNOSTIC OPERATING INSTRUCTIONS is displayed, follow the displayed instructions to checkout the desired resources. 6. When testing is complete; use the F3 key to return to DIAGNOSTIC OPERATING INSTRUCTIONS. Then press the F3 key again to return to the AIX operating system prompt. 7. Press Ctrl-D to log off from root or superuser.
7. Follow the displayed instructions to check out the desired resources. 8. When testing is complete; use the F3 key to return to the DIAGNOSTIC OPERATING INSTRUCTIONS. Location Codes This system unit uses Physical Location Codes in conjunction with AIX Location Codes to provide mapping of the failing field replaceable units (FRUs). The location codes are produced by the system unit's firmware and AIX.
Each location identifier consists of one alpha prefix character that identifies a location type, and a decimal integer number (typically one or two digits) that identifies a specific instance of this location type. Certain location types may also support secondary sub-locations, which are indicated by appending a period (".") character and a sub-location instance number. Specifically, the format of a location code is defined as follows: pn[.n][- or /]pn[.n][- or /]...
AB-CD-EF-GH | | | | | | | Device/FRU/Port ID | | Connector ID | devfunc Number, Adapter Number or Physical Location Bus Type or PCI Parent Bus The AB value identifies a bus type or PCI parent bus as assigned by the firmware. The CD value identifies adapter number, adapter's devfunc number, or physical location. The devfunc number is defined as the PCI device number times 8, plus the function number. The EF value identifies a connector. The GH value identifies a port, address, device, or FRU.
GH is used to identify a port, device, or FRU. For example: For async devices GH defines the port on the fanout box. The values are 00 to 15. For a diskette drive H defines which diskette drive 1 or 2. G is always 0. For all other devices GH is equal to 00. For integrated adapter, EF-GH is the same as the definition for a pluggable adapter. For example, the location code for a diskette drive is 01-D1-00-00. A second diskette drive is 01-D1-00-01.
Examples of AIX location codes displayed are: Integrated PCI adapter 10-80 10-60 30-58 10-88 Ethernet Integrated SCSI Port 1 Integrated SCSI Port 2 (Model 50 only) Integrated SCSI Port 2 (Model 70 only) Pluggable PCI adapters 20-58 20-60 10-68 10-70 10-78 30-60 40-58 40-60 30-68 30-70 30-78 to to to to to to to to to to to 20-5F 20-67 10-6F 10-77 10-7F 30-67 40-5F 40-67 30-6F 30-77 30-7F Any Any Any Any Any Any Any Any Any Any Any PCI PCI PCI PCI PCI PCI PCI PCI PCI PCI PCI card card card card card c

Introduction to Service Aids The diagnostics contain programs called service aids. The service aids are used to display data and do additional testing. Options for the service aids are available when the software package for that option is installed. The service aids are selected via the Task Selection Menu. Refer to the table on the previous pages for a listing of service aids which are provided. Chapter 7.
The following are descriptions of the service aids: AIX Shell Prompt Service Aid This service aid allows access to the AIX command line. In order to use this service aid the user must know the root password (when a root password has been established). Backup/Restore Media Service Aid This service aid allows verification of backup media and devices. It presents a menu of tape and diskette devices available for testing and prompts for selection of the desired device.
Call In allows the Service Processor to receive a call from a remote terminal. Call Out Authorized on S1 (on/off) Call Out Authorized on S2 (on/off) Call Out allows the Service Processor to place calls for maintenance. S1 Line Speed S2 Line Speed A list of line speeds is available by using List on the screen. Service Center Phone Number This is the number of the service center computer. The service center usually includes a computer that takes calls from systems with call-out capability.
This is set to either first or all. If the call-out policy is set to first, call out will stop at the first successful call to one of the following numbers in the order listed: 1. Service Center 2. Customer Admin Center 3. Pager If call out policy is set to all, call out will attempt to call all or the following numbers in the order listed: 1. Service Center 2. Customer Admin Center 3. Pager Customer RETAIN Login ID Customer RETAIN Login Password These settings apply to the RETAIN service function.
Power On Via Ring Indicate (on/off) Number of Rings Before Power On This service aid may be accessed directly from the AIX command line, by entering: /usr/lpp/diagnostics/bin/uspchrp -r Configure Surveillance Policy Service Aid This service aid monitors the system for hang conditions, that is, hardware or software failures that cause operating system inactivity. When enabled, and surveillance detects operating system inactiviy, a call is placed to report the failure.
Note: A value of 0 indicates "do not attempt to reboot" to a crashed system. This number is the maximum number of consecutive attempts to reboot the system. The term reboot, in the context of this service aid, is used to describe bringing system hardware back up from scratch, for example from a system reset or power on. Once the Maximum Number of Reboot Attempts is exceeded, the system will call out if that function has been enabled.
This service aid may be accessed directly from the AIX command line, by entering: /usr/lpp/diagnostics/bin/uspchrp -b Save or Restore Hardware Management Policies Service Aid This service aid is used with Ring Indicate Power On Policy, Surveillance Policy, Remote Maintenance Policy and Reboot Policy.
Dials and LPFK Configuration Service Aid This service aid provides a tool for configuring and removing dials/LPFKs to the standard serial ports. The Dials and LPFKs can be configured on any async port. A tty must be in the available state on the async port before the Dials and LPFKs can be configured on the port. The task allows an async adapter to be configured, then a tty port defined on the adapter, and then Dials and LPFKs can be defined on the port.
This option can be used to overwrite (remove) all data currently stored in useraccessible blocks of the disk. The Erase Disk option writes one or more patterns to the disk. An additional option allows data in a selectable block to be read and displayed on the system console. To use the Erase Disk option, specify the number (0-3) of patterns to be written. Select the patterns to be written; the patterns are written serially. That is, the first pattern is written to all blocks.
Disk Maintenance Service Aid There are two kinds of disk maintenance service aids: Disk to Disk Copy Service Aid Display/Alter Sector Service Aid Disk to Disk Copy Service Aid The service aid allows you to recover data from an old drive when replacing it with a new drive. The service aid only supports copying from a drive to another drive of similar size; it cannot be used to update a different size drive. The migratepv command should be used when updating drives.
Display/Alter Sector Service Aid This service aid allows the user to display and alter information on a disk sector. Care must be used when using this service aid because inappropriate modification to some disk sectors may result in total loss of all data on the disk. Sectors are addressed by their decimal sector number. Data is displayed both in hex and in ASCII. To prevent corrupted data from being incorrectly corrected, the service aid will not display information that cannot be read correctly.
Display or Change Configuration or Vital Product Data (VPD) Service Aid This service aid allows the user to display change configuration data and vital product data (VPD).
Change Hardware Vital Product Data Task Use this service aid to display the Display/Alter VPD Selection Menu. The menu will list all resources installed on the system. When a resource is selected a menu is displayed that lists all the VPD for that resource. Note: The user cannot alter the VPD for a specific resource unless it is not machine readable. Add Resource to Resource List Task Use this task to add resources back to the resource list.
Display and Change Diagnostic Test List Service Aid This service aid provides a way to: Display the Diagnostic Test List This selection lists all of the resources tested by the diagnostics. Add a resource to the Diagnostic Test List This selection allows resources to be added back to the Diagnostic Test List. The Diagnostic Test List Menu lists all resources that can be added back to the Diagnostic Test List.
Display Test Patterns Service Aid This service aid provides a means of making adjustments to system display units by providing displayable test patterns. Through a series of menus the user selects the display type and test pattern. After the selections are made the test pattern is displayed. Enhanced SCSI Display Configuration Service Aid This service aid allows the user to choose a SCSI device or location from a menu and to identify a device.
Hardware Error Report Service Aid and Display Hardware Error Log Task This service aid provides a tool for viewing the hardware error log. It uses the errpt command. The Display Error Summary and Display Error Detail selection provide the same type of report as the errpt command. The Display Error Analysis Summary and Display Error Analysis Detail selection provide additional analysis.
error log and cleared from NVRAM when the system is rebooted from either hard disk or LAN. The information is not cleared when booting from Standalone Diagnostics. When booting from Standalone Diagnostics, this service aid can take the logged information and turn it into a readable format that can be used to isolate the problem. When booting from the hard disk or LAN, the information can be viewed from the AIX error log using the Hardware Error Report Service Aid.
To use this service aid, the user should have an understanding of how a SCSI bus works. This service aid should be used when the diagnostics cannot communicate with anything on the SCSI bus and cannot isolate the problem. Normally the procedure for finding a problem on the SCSI bus with this service aid is to start with a single device attached, ensure that it is working, then start adding additional devices and cables to the bus ensuring that each one works.
Notes: A check condition can be returned when there is nothing wrong with the bus or device. AIX does not allow the command to be sent if the device is in use by another process. SCSI Tape Utilities Service Aid This service aid provides a means to obtain the status or maintenance information from a SCSI tape drive. Only some models of SCSI tape drive are supported. The service aid provides the following options: Display time since a tape drive was last cleaned.
Update System or Service Processor Flash Service Aid Note: This service aid is only supported for Online Diagnostics This service aid allows you to update the system or service processor flash. Additional update and recovery instructions may be provided; also you need to know the fully qualified path and file name of the flash update image file. If the flash update image file is on a diskette, you need the AIX DOS utilities package to process the diskette.
7135 RAIDant Array Service Aid The 7135 RAIDant Array service aids contain the following functions: Certify LUN This selection reads and checks each block of data in the LUN. If excessive errors are encountered the user will be notified. Certify Spare Physical Disk This selection allows the user to certify (check the integrity of the data) on drives designated as spares. Format Physical Disk This selection is used to format a selected disk drive.
SSA Location Code Format Location codes identify the locations of adapters and devices in the using system and their attached subsystems and devices. These codes are displayed when the diagnostic programs isolate a problem. For information about the location codes that are used by the using system, see the operator guide for the using system.
SSA Loops and Links The disk drive modules of the system unit are connected through two SSA links to an SSA adapter that is located in the using system. The disk drive modules, SSA links, and SSA adapter are configured in loops. Each loop provides a data path that starts at one connector of the SSA adapter and passes through a link (SSA cable) to the disk drive modules. The path continues through the disk drive modules, then returns through another link to a second connector on the SSA adapter.
The SSA links must be configured as loops. The loop is connected to the internal connectors at the SSA adapter card. These connectors must be a valid pair (that is, A1 and A2, or B1 and B2); otherwise, the disk drive modules on the loop are not fully configured, and the diagnostics fail. Operations to all the disk drive modules on a particular loop can continue if that loop breaks at any one point.
Pdisks, Hdisks, and Disk Drive Module Identification The physical disk drives (pdisks) in an SSA subsystem can be configured as logical units (LUNs). A LUN is also known as an hdisk, and can consist of one or more physical disk drives. An hdisk in an SSA subsystem might therefore consist of one or more pdisks. The configuration software also allocates an identification (hdisk and pdisk number) to each disk drive module during the configuration of the SSA link.
Loops and Data Paths All devices that are attached to an SSA adapter card are connected through SSA links. The SSA links are configured as loops. Data and commands to a particular device pass through all other devices on the link between the adapter and the target device. Data can travel in either direction around a loop. The adapter can, therefore, access the disk drive modules through two data paths. The using system cannot detect which data path is being used.
If two or more disk drive modules are turned off, fail, or are removed from the loop, some modules might become isolated from the SSA adapter. The following diagram shows that the disk drive modules in slots 2 and 4 have failed. The disk drive module in slot 1 can communicate with the using system only through connector A1 of the SSA adapter. The disk drive module in slots 5 and 6 can communicate with the using system only through connector A2 of the SSA adapter.
SSA Service Aids SSA service aids help you service the SP. This section describes those service aids, and tells how to use them. Attention: Do not run the service aids from more than one system at a time; otherwise, unexpected results might occur. The SSA service aids are: Set Service Mode This service aid enables you to determine the location of a particular disk drive module on the SSA link and to remove that module from the link.
The Identify Function The identify function can be accessed from any of the service aids. This function enables you to determine the location of a particular disk drive module that you want to identify but do not want to remove from the system unit. The identify function causes the check light of the disk drive module to flash for identification (1 second on, 1 second off), but has no effect on the normal operation of the disk drive module.
Note: In some configurations of the using-system console: Esc and 0 = Exit Esc and 3 = Cancel In such configurations the displayed instructions for the function keys remain the same as those shown in the SSA SERVICE AIDS menu. 5.
Set Service Mode Service Aid The Set Service Mode service aid enables you to determine the location of a particular disk drive module and to remove that module from the system unit. It causes the check light of that disk drive module to come on for identification, and it stops all SSA link activity through the module. Only one disk drive module at a time can be in the service mode.
The columns of information displayed on the SSA SERVICE AIDS menu have the following meanings: pdisk0 through pdisk8 Physical disk drive resource identifiers. 11111111 through 99999999 Serial numbers of the physical disk drive modules. The actual serial number of a disk drive module is shown on the front of the disk drive module. 00-04-P See “SSA Location Code Format” on page 7-24. 9.1 GB SSA F Physical Disk Drive Descriptions of the disk drive modules. 2.
3. Select either the service mode or the identify function. (For this example, assume that you have selected the service mode function.) The list of pdisks is displayed again, and the disk drive module that you selected is marked by a >, which shows that the module is in the service mode.
4. Select a second disk drive module, if required (for example, pdisk5).
5. Select either the service mode or the identify function. If the original disk drive module is to remain in service mode, you can select only the identify function now. (Only one disk drive module at a time can be in the service mode.) The list of pdisks appears again. The pdisk that is in identify mode is identified by a +.
Link Verification Service Aid The Link Verification service aid helps you determine: Where an SSA link has been broken The status of the disk drive modules on that SSA link The location of a power fault that has been detected by the disk drive modules on that SSA link To use the Link Verification service aid: 1. Select Link Verification from the SSA Service Aids menu (see “Starting the SSA Service Aids” on page 7-31).
3.
from either direction, the broken loop does not prevent access to any data, unless that data is on the failed disk drive module. If the loop is broken between two disk drive modules, the ready lights on those modules flash to show that only one SSA path is active. Also, the Link Verification service aid shows that only one path is available to each disk drive module on the broken loop.
b. If you have just made changes to or have just turned on the system unit, you might need to wait up to 30 seconds before detailed information about the SSA network becomes available to the service aids. 4. When you have solved a problem, press F3 (Esc and 3 on some consoles) to leave the display; then press Enter to reselect it. The display shows the new status of the SSA links.
2. Select the hdisk or pdisk that you want to test. 3.
Format Disk Service Aid The Format Disk service aid formats SSA disk drive modules. Attention: Formatting a disk drive module destroys all the data on that module. Use this procedure only when instructed to do so by the service procedures. To use the Format Disk service aid: 1. Select Format Disk from the SSA Service Aids menu (see “Starting the SSA Service Aids” on page 7-31).
2. Select the pdisk that you want to format. The following instructions are displayed: ┌──────────────────────────────────────────────────────────────────────────────────┐ │ SSA SERVICE AIDS 8ð238ð │ ┌──────────────────────────────────────────────────────────────────────────────────┐ │ FORMAT DISK 8ð2395 │ ┌──────────────────────────────────────────────────────────────────────────────────┐ │ FORMAT DISK 8ð2396 │ │ │ │ pdisk1 22222222 ðð-ð4-P 9.1 GB SSA F Physical Disk Drive │ │ │ │ Set or Reset Identify.
Certify Disk Service Aid The Certify Disk service aid verifies that all the data on a disk drive module can be read correctly. Instruction given elsewhere in this book tell you when you need to run this service aid. To use the Certify Disk service aid: 1. Select Certify Disk from the SSA Service Aids menu (see “Starting the SSA Service Aids” on page 7-31).
2. Select the pdisk that you want to certify. The following instructions are displayed: ┌──────────────────────────────────────────────────────────────────────────────────┐ │ SSA SERVICE AIDS 8ð238ð │ ┌──────────────────────────────────────────────────────────────────────────────────┐ │ CERTIFY DISK 8ð24ð4 │ ┌──────────────────────────────────────────────────────────────────────────────────┐ │ CERTIFY DISK 8ð24ð5 │ │ │ │ pdisk1 22222222 ðð-ð4-P 9.
Service Aid Error Codes If the SSA service aids detect an unrecoverable error and are unable to continue, one of the following error codes might occur: SSA01 Not enough using-system memory is available for this service aid to continue. Take one of the actions described here: This problem might be caused by a failed application program. Ask the user to end any failed application program, then try to run the service aid again. Run diagnostics in the problem determination mode on the system unit.
Using the Service Aids for SSA-Link Problem Determination If you have a problem with an SSA link, use the Link Verification service aid (see “Link Verification Service Aid” on page 7-38). The following examples show various loops and the associated information that is displayed by the Link Verification service aid. Example 1. Normal Loops In the following diagram, eight disk drive modules are connected to connectors A1 and A2 of the SSA adapter.
For this example, the Link Verification service aid displays the following information: ┌──────────────────────────────────────────────────────────────────────────────────┐ │ LINK VERIFICATION 8ð2386 │ │ │ │ SSA Link Verification for: │ │ ssa1 ðð-ð5 SSA ADAPTER │ │ │ │ To set or reset Identify, move cursor onto selection, then press Enter.
Example 2. Broken Loop (Cable Removed): Each disk drive module normally communicates with the adapter through one data path. Because data can pass around the loop in either direction, however, the adapter automatically reconfigures the loop to enable communication to continue to each disk drive if the loop becomes broken. In the following diagram, eight disk drive modules should be connected to connectors A1 and A2 of the SSA adapter.
For this example, the Link Verification service aid displays the following information: ┌──────────────────────────────────────────────────────────────────────────────────┐ │ LINK VERIFICATION 8ð2386 │ │ │ │ SSA Link Verification for: │ │ ssa1 ðð-ð5 SSA ADAPTER │ │ │ │ To set or reset Identify, move cursor onto selection, then press Enter.
Example 3. Broken Loop (Disk Drive Module Removed): The following diagram shows eight disk drive modules connected to connectors A1 and A2 of the SSA adapter, but the loop is broken because disk drive module in slot 3 has been removed. Four disk drive modules are connected to connectors B1 and B2 of the same SSA adapter. Although the missing disk drive module is reported as an error, all the remaining disk drive modules can still communicate with the using system.
For this example, the Link Verification service aid displays the following information: ┌──────────────────────────────────────────────────────────────────────────────────┐ │ LINK VERIFICATION 8ð2386 │ │ │ │ SSA Link Verification for: │ │ ssa1 ðð-ð5 SSA ADAPTER │ │ │ │ To set or reset Identify, move cursor onto selection, then press Enter.
Finding the Physical Location of a Device The physical location of a device (for example, a disk drive module or an SSA adapter) cannot be reported directly by the using system because of the way in which the SSA interface works. The address of an SSA device is related to the position of that device on the SSA loop. The address can, therefore, change if the configuration is changed.
SSA-address count by 1 for each device, until you reach the disk drive module or adapter that is indicated in the SRN. Microcode Maintenance Updates to the microcode are loaded into the using system from diskettes.
Vital Product Data (VPD) The vital product data (VPD) for the system unit and for the SSA adapter can be displayed by using the using-system service aids. This section shows the types of information that are contained in the VPD. Abbreviations used in this section are: DRAM FRU RAM ROM ROS SSA Dynamic random-access memory Field-replaceable unit Random-access memory Read-only memory Read-only storage Serial storage architecture The VPD for the 4.5 GB and 9.
Chapter 8. Using the System Verification Procedure The system verification procedure is used to check the system for correct operation. When you are analyzing a hardware problem, see Chapter 9 on page 9-1. Step 1. Considerations before Running This Procedure Notes: 1. If this system unit is directly attached to another system unit or attached to a network, be sure communications with the other system unit is stopped. 2. This procedure requires use of all of the system resources.
Step 2. Loading the Diagnostics 1. Stop all application programs running on the operating system. 2. Stop the operating system. 3. Turn the power off. 4. If you are loading the Standalone Diagnostics and running them from an ASCII terminal: The attributes for the terminal must be set to match the defaults of the diagnostics. If you need to change any settings, record the normal settings, and be sure the terminal attributes are set to work with the diagnostics.
Step 3. Running System Verification The Diagnostic Operating Instructions should be displayed. 1. Press the Enter key. 2. If the terminal type has not been defined, you must use the Initialize Terminal option on the Function Selection menu to initialize the operating system environment before you can continue with the diagnostics. 3. If you want to do a general checkout without much operator action, Select the Diagnostic Routines option on the Function Selection menu.
Step 5. Stopping the Diagnostics 1. If you are running the Online diagnostics, use the folowing procedure to shut down the system: a. Press F3 repeatedly until you get to the Diagnostic Operating Instructions, then follow the displayed instructions. b. Press F3 once, and then follow the displayed instructions to shut the system down. 2. If you changed any attributes on your ASCII terminal to run the diagnostics, change the settings back to normal. 3. This completes the system verification.
Chapter 9. Hardware Problem Determination Problem Determination Using the Standalone or Online Diagnostics Use this procedure to obtain a service request number (SRN) when you load the Standalone or Online Diagnostics. If you are unable to load the Standalone or Online Diagnostics, go to “Problem Determination When Unable to Load Diagnostics” on page 9-10. The service organization uses the SRN to determine which field replaceable units (FRUs) are needed to restore the system to correct operation. Step 1.
Step 3 Determine if the operating system is accepting commands. Is the operating system accepting commands? NO The system must be turned off in order to run diagnostics. 1. Verify with the system administration and users that the system may be turned off. If so, then turn off the system unit and go to “Step 6.” YES Go to “Step 4.” Step 4 Diagnostic tests can be run on many resources while the operating system is running.
Step 5 This step invokes the Online Diagnostics in concurrent mode. 1. Log on as root or as superuser. 2. Enter the diag command. 3. Wait until the Diagnostic Operating Instructions are displayed, or wait for three minutes. Are the Diagnostic Operating Instructions displayed without any obvious console display problems? NO Do the following steps to shut down the system: 1. At the system prompt, stop the operating system using the proper command for your operating system. 2.
Step 7 Starting at the top of the following table, find your symptom and do the action given in the Action column. Symptom Action Display problem. Go to “Step 8.” All other symptoms. Go to “Problem Determination When Unable to Load Diagnostics” on page 9-10 Step 8 The following steps analyze a console display problem. Find your type of console display in the following table, then do the action given in the Action column.
Step 10 There is a problem with the keyboard. Find the type of keyboard you are using in the following table, then follow the instructions given in the Action column. Keyboard Type Action 101–key keyboard. Identify by the type of Enter key used. The Enter key is within one horizontal row of keys. Record error code M0KBD001 and report the problem to the service organization. 102–key keyboard. Identify by the type of Enter key used. The Enter key extends into two horizontal rows of keys.
Step 11 1. If the terminal type has not been defined, you must use the Initialize Terminal option on the Function Selection menu to initialize the operating system environment before you can continue with the diagnostics. This is a separate and different operation than selecting the console display. 2. Select Diagnostic Routines. 3. Press the Enter key. 4. In the following table, find the menu or system response you received when you selected Diagnostics. Do the action given in the Action column.
Step 12 Did the Diagnostic Selection Menu display? NO If Problem Determination was selected from the Diagnostic Mode Selection menu, and if a recent error has been logged in the error log, the diagnostics automatically begin testing the resource. Follow the displayed instructions. If the No Trouble Found screen is displayed, press Enter. If another resource is tested, repeat this step. If the Diagnostic Selection menu is displayed, go to “Step 13.” If an SRN is displayed, record it, and go to “Step 14.
Step 14 The diagnostics produced a SRN for this problem. 1. Record the SRN and other numbers read out. 2. Report the SRN to the service organization. 3. STOP. You have completed these procedures. Step 15 When you are loading the Standalone Diagnostics, the attributes for the terminal must be set to match the defaults of the diagnostic programs. The ASCII terminal must be attached to serial port 1 on the system unit.
Step 16 This step loads the Standalone Diagnostics. If you are unable to load the diagnostics, go to “Step 7.” 1. Turn the power on. 2. Insert the diagnostic CD-ROM disc into the CD-ROM drive. 3. When the keyboard indicator appears, press F5 on the direct attached keyboard or 5 on the ASCII keyboard to indicate that diagnostics are to be loaded. 4. Enter requested passwords. 5. Follow instructions to select a console.
Problem Determination When Unable to Load Diagnostics Use this procedure to obtain an error code. The service organization uses the error code to determine which field replaceable units (FRUs) are needed to restore the system to correct operation. Step 1. Considerations before Running This Procedure The diagnostics can use a display connected to the video port or a ASCII terminal attached to a serial port. Go to “Step 2.” Step 2 Are the Online Diagnostics installed on this system? NO Go to “Step 4.
Step 3 This step attempts to load Online Diagnostics in service mode. 1. Turn the power to off. 2. Turn the power on. 3. If the keyboard indicator appears, press F6 on the direct attached keyboard or 6 on the ASCII keyboard to indicate that diagnostics are to be loaded. 4. Enter requested passwords. 5. Follow instructions to select a console. 6. Wait until the diagnostics load or the system appears to stop. Did the diagnostics load? NO Go to “Step 5.” YES Go to “Step 6.
Step 5 Starting at the top of the following table, find your symptom and do the action given in the Action column. Symptom Action The power LED does not come on, or comes on and does not stay on. Check the power cable to the outlet. Check the circuit breakers and check for power at the outlet. Assure the room temperature is within 60 90°F. If you do not find a problem, record error code M0PS0000 and report the problem to the service organization.
Symptom Action The system does not respond when the password is entered. Go to "Step 7". The system stopped and an indicator is displayed on the system console and an eight-digit error code is not displayed. If the indicator (text or icon) represents: a keyboard, record error code M0KBD000 and report the problem to the service organization. memory, record error code M0MEM002 and report the problem to the service organization.
Step 6 The diagnostics loaded correctly. Go to “Problem Determination Using the Standalone or Online Diagnostics” on page 9-1. Step 7 There is a problem with the keyboard. Find the type of keyboard you are using in the following table, then follow the instructions given in the Action column. Keyboard Type Action 101–key keyboard. Identify by the type of Enter key used. The Enter key is within one horizontal row of keys. Record error code M0KBD001 and report the problem to the service organization.
Chapter 10. SSA Problem Determination Procedures Problem determination procedures are provided by power-on self-tests (POSTs), service request numbers (SRNs), and maintenance analysis procedures (MAPs). Some of these procedures use the using system service aids that are described in “Introduction to Service Aids” on page 7-3. Disk Drive Module Power-On Self-Tests (POSTs) Attention: Disk drive modules are fragile. Handle them with care.
Adapter Power-On Self-Tests (POSTs) Two power-on self-tests (POSTs) are resident in the SSA adapter. The tests are POST-1 and POST-2. POST-1 tests all the functions that are necessary to enable the adapter to communicate with the Micro Channel. POST-1 can fail for either of two reasons: A hardware error has been detected. In such instances, the POST code enters a tight loop, and does not put the identification of the SSA adapter into the programmable option select (POS) registers.
Appendix A. System Records Record the Identification Numbers Record and retain the following information. Product Name RS/6000 Enterprise Server Model H Series CPU Type/Speed Serial Number Key Serial Number The server's identification numbers are located on the front cover and on the rear of the server. Appendix A.
Device Records Use the following tables to keep a record of the options installed in or attached to your system. This information can be helpful when you install additional options in your server or if you ever need to have your server serviced. Table A-1.

Appendix B. Service Processor Setup and Test For your convenience, here is an example Service Processor setup checklist. It is basic. Your setup may include more or less of the available features, so you may wish to adjust this checklist for your own application. This checklist will at least provide you with a starting place. Service Processor Setup Checklist 1. Unplug the power cord from the server. 2. Attach a local terminal for this setup procedure. 3. Plug in the server and power on the local terminal.
Testing the Setup The following is a sample procedure to assure your setup is working. These tests include communicating with the server operating system. Be sure the necessary serial port(s) is configured. If you need assistance, refer to “Serial Port Configuration” on page B-4. The server should be powered off as a result of the “Service Processor Setup Checklist” on page B-1. Call-In: 1. Go to your remote terminal and call-in to your server.
Call-Out: During the setup, you entered your phone numbers for the Pager (on page 3-19) and Customer Voice (on page 3-20). These numbers are used for this test. 1. Your remote terminal is disconnected as a result of the Call-In test. 2. Call your server again. 3. At the Service Processor Main Menu, select Call-In/Call-Out Setup menu, then select Call-Out test. This causes a simulated error condition for the purposes of this test. 4. After a few moments, a message appears regarding an illegal entry.
Serial Port Configuration To configure the serial port on an AIX system, enter the following commands from an AIX console: 1. Log in as root. 2. To find if you have any serial ports already configured, enter: lsdev -Cc tty If no serial ports are configured, none are listed. If you wish to configure serial ports that are not listed, continue with the remaining steps. 3. Identify the serial port(s) with the modem(s). 4. Enter smit tty 5. Select add tty 6. Select RS232 7. Select Baud rate 96ðð or higher. 8.
Appendix C. Modem Configurations Sample Modem Configuration Files With hundreds of modems to choose from, and various modem programming standards, configuring a modem for use with the RS/6000 High Availability Cluster Server High Availability Solution can be challenging. The RS/6000 High Availability Cluster Server - High Availability Solution is designed to place little demand on an attached modem, thereby increasing the setup and connection success rates.
Configuration File Selection 1. Is your modem an IBM 7852-400? If Yes, use modem configuration file modem_m0.cfg and go to step 7 on page C-3. Note: The IBM 7852-400 modem has dip switches on the right hand side of the unit. See “IBM 7852-400 DIP Switch Settings” on page C-4 for the correct switch settings. If No, continue with step 2. 2. Is your modem an IBM 7857-017? If Yes, use modem configuration file modem_m1.cfg and go to step 7 on page C-3.
a. AT&F reset command, or b. AT&Fn reset commands, where n can be 0, 1, etc.? If AT&F, configuration file modem_f.cfg is recommended. If AT&Fn, configuration file modem_f0.cfg or modem_f1.cfg is recommended, depending on which provides the hardware flow control profile. 7. Selection is complete. If your modem configuration selection is not available in the Service Processor Modem Configuration Menu, you must access it through the Configure Remote Maintenance Policy Service Aid.
Customizing the Modem Configuration Files You can create your own modem configuration files or modify the samples provided. After you customize your modem configuration files, you MUST access them via the Configure Remote Maintenance Policy Service Aid rather than from the Service Processor menus. Note: If you have already set up your serial ports, line speeds, authorizations and telephone numbers from the Service Processor menus, specify your customized modem configuration files from the service aid.

Xon/Xoff Modems Some modems of the mid-80's vintage assume software flow control (Xon/Xoff) between the computer and the modem. Modems with this design send extra characters during and after the transmitted data.
The server's operating system will have some built-in terminal emulators. You may also have a commercially available terminal emulation. It is important that the local and host computers select the same or compatible terminal emulators so the key assignments and responses will match. This will assure successful communications and control. For best formatting, choose line wrap in your terminal emulator setup. Recovery Procedures Line noises, power surges, etc.
Usually the command &D2 will work, but not always. The sample modem configuration files1 take this high percentage position. You should consult your modem manual for its specific response scheme for the &Dn command. There are two methods for dealing with the modem's response to DTR: 1. Recovery 2. Prevention Before proceeding with one of these strategies, you need to determine if your server's modem is set up properly to respond to DTR.
Recovery Strategy The recovery strategy consists of making two calls to establish a remote session. This is the easiest solution to implement, and allows more freedom for configuring your server's serial ports. To set up a remote terminal session, dial into the Service Processor and start the system. After the operating system is loaded and initialized, the connection will be dropped. At this point, you call the server back and the operating system will answer and offer you the login prompt.

Appendix D. Service Processor Operational Phases This section provides a high-level flow of the phases of the Service Processor (SP). SP Power Applied │ 6 ┌─────┐ Pre-Standby Phase │ 6 │ │ 6 │ Standby Phase SP Menus Available │ │ │ 6 │ Bring-Up Phase SMS Menus Available │ │ │ 6 │ Runtime Phase Diagnostic Service Aids Available │ │ └──────────────────┘ Pre-Standby Phase This phase is entered when the server is connected to a power source. The server may or may not be fully powered on.
Standby Phase The standby phase can be reached in two ways: 1. With the server OFF and power connected (the normal path), recognized by OK in the LCD display 2. With the server ON after an operating system fault, recognized by STBY or an 8-digit code in the LCD display In the Standby phase, the SP takes care of some automatic duties and is available for menus operation. The SP remains in the standby phase until a power-on request is detected.
The SP can dial a pre-programmed telephone number in the event of an IPL failure. The SP issues an error report with the last reported IPL status indicated and any other available error information. Update Operator Panel The SP displays Operator Panel data on the ASCII terminal if a remote connection is active. Environmental Monitoring Environmental Monitoring is now controlled by the SP instead of the base system, with expanded error recording and reporting.
