1 Introduction Chapter Overview This chapter contains information on the following: ■ How the Interface Manager (IM) Works on page 12 ■ Processing SCSI Information on page 14 ■ Interface Manager (IM) Features on page 15 ■ Interface Manager (IM) Components on page 17 ■ Specifications on page 19 ■ Supported Products on page 20 Introduction 11
How the Interface Manager (IM) Works The IM provides connectivity between a Fibre Channel (FC) switched fabric (FC-SW) or Fibre Channel arbitrated loop (FC-AL) and up to 20 Ultra-2 SCSI buses. The IM contains slots for up to eleven (one slot is reserved for future expansion) Fibre Channel cards. Each card connects a FC port to two Ultra-2 SCSI ports. The IM also contains a Remote Management Card (RMC) in slot 1, and a controller card in slot 2.
Chapter 1 Figure 1 shows the front view of the Interface Manager.
Processing SCSI Information The following section describes how the Interface Manager (IM) processes SCSI information when attached to Fibre Channel (FC) hosts. 1. A FC host issues a command. The FC host encapsulates the SCSI command in the FC protocol and sends the packet to the IM. 2. The FC card in the IM receives the packet, interprets the FC information, and places the packet in buffer memory. 3. The IM’s processor interprets the information and programs a SCSI controller to process the transaction. 4.

Interface Manager Overview 2 Chapter Overview This chapter contains information on the following: ■ Overview of the Interface Manager (IM) Configuration on page 24 ■ Choosing the Right Configuration on page 25 Chapter Overview 23
Overview of the Interface Manager (IM) Configuration The IM can be configured through one of several user interfaces: ■ Over a serial port via a terminal or terminal emulation utility ■ Over Ethernet via a Telnet utility, Internet Web browser, or SNMP management tool Note Before configuring the Interface Manager, a basic understanding of Fibre Channel and SCSI devices is recommended.
Choosing the Right Configuration Chapter 2 Choosing the Right Configuration 25 Chapter 2 The factory default settings of the Interface Manager (IM) permit the type of configuration shown in Figure 3 on page 26 (standard configuration) to work without any initial changes to these settings. The IM settings may need to be changed for expanded configurations (see Figure 4 on page 27) or certain application requirements.
Figure 3 26 Example of a Standard Configuration in a 20/700 Tape Library Choosing the Right Configuration Chapter 2
Figure 4 Expanded Configuration Chapter 2 Chapter 2 Choosing the Right Configuration 27
A standard configuration may involve several Fibre Channel (FC) hosts connected to multiple FC cards. These FC host systems may be connected to the cards either in a point-to-point (PPP) fashion or through a FC switch. Each card is then connected to two SCSI tape drives. The library’s robotics controller may be daisy-chained with one of the SCSI tape drives or connected directly to an available FC interface card SCSI port, or direct connect SCSI to host.
Fibre Channel Arbitrated Loop Addressing On a FC arbitrated loop, each device appears as an Arbitrated Loop Physical Address (AL_PA). To obtain an AL_PA, two methods called soft and hard addressing can be used by the IM. The IM can be configured to use either method. Hard addressing is recommended for FC arbitrated loop environments where it is important that the FC device addresses do not change. Device address changes can affect the mapping represented by the host operating system to the application.
Host Device Configuration The host system using a FC host bus adapter (HBA) will typically map FC devices into the existing device mapping scheme used by that operating system. (Refer to your HBA manual for the mapping table.) The FC usually maps FC addresses to SCSI target addresses. In such a configuration, the IM corresponds to a bus:target identifier, with the SCSI devices attached to the IM appearing as logical units (LUNs).
Commands other than Write are not issued until status is received for any pending Write. Also, status is not returned until the device completes the command. For instance, when a synchronizing command is sent to the drive, such as sending a Write File mark, a good status means all prior commands have been successfully completed and data has been successfully written to the medium. This is appropriate for such tasks as file backup/restore.
Auto-Indexed Mapping This is the default method of operation. Discovery of SCSI devices is performed at every startup (power up, or reboot). As devices are discovered, they are added to the FC-to-SCSI mapping table. The FC LUN numbers are assigned sequentially. The mapping table is stored in FLASH memory. An example of a FC-to-SCSI map for three SCSI devices is shown in Table 1.
Configuration Methods The IM can be configured over the serial port via a terminal, terminal emulation utility or over Ethernet via a Telnet utility, Internet Web browser, or SNMP management tool. FTP is also supported on Ethernet to upgrade firmware revisions. Chapter 2 Serial The serial port allows for configuration of device characteristics from an attached terminal or terminal emulator.
Web Based Administrator The IM allows any standard Internet Web browser to view and change the IM configuration. Information is dynamically generated in an HTML format by the IM so that Web browsers can access it. To access the Web interface, enter the IP address of the IM into the address field of a Web browser. Or, you can enter a URL using a host name defined by the user.

Take note of the settings in the table shown on the screen above the Fibre Channel Address Configuration menu. If these are not acceptable, you may choose to edit them one at a time, or you may use Hewlett-Packard’s recommended settings. Note Hard Addressing To use the recommended hard address settings: Caution Re-starting an interface card will stop any data flowing through that interface card, so any backup in progress will fail. 1.
Soft Addressing There are some conditions that require the Fibre Channel interface cards to be set to Soft addressing. This is easily done on all interface cards at once by doing the following: Caution Re-starting an interface card will stop any data flowing through that interface card, so any backup in progress will fail. 1. Select [2] from the Fibre Channel Address Configuration menu to place the Pending settings to Soft mode. 2.
4. If you selected hard addressing, you will be asked to supply an address to be used. It is expected that the number will be entered in hexadecimal. If you enter a zero, then the Auto-Select feature will be enabled. Only certain ALPA values are valid, if you choose an invalid address, then you will be asked to try again. 5. You will now be asked whether the card should be re-started when this new address setting is applied to the selected interface card.
Figure 6 Interface Manager Bus and Slot Locations Note Slot number1 should contain the RMC (disregard the card type number 2 on the card, the correct slot number is 1). Slot number 2 should contain the Controller card (disregard the card type number 3 on the card, the correct slot number is 2). Interface cards are in slots numbered 3 through 12. 5. The upper right LED on the card should turn yellow. When it does, you can remove the card.
Placing a Fibre Channel Interface Card On-Line Using Telnet To replace a Fibre Channel interface card with a new one, do the following: 1. BEFORE installing the interface card into the Interface Manager, attach the SCSI cable that was removed from the old card, to the correct bus on the new card based on the connections printed on the cable label. 2. Insert the new FC interface card into the slot where the old card was removed.
5. Select [5] from the Interface Card menu to inform the firmware that you have installed a new interface card. You will be asked to supply the slot number of the interface card to place On-Line. 6. Wait for the RDY LED to turn green. It may takes 1 to 2 minutes to reach that point in the boot-up process. It takes several minutes before the interface card is ready to report its status back to the RMC.
Installing a New Fibre Channel Interface Card Using Telnet To insert a new interface card into an available slot numbered 3 through 12 (see Figure 6 on page 46), do the following: 1. Using the cable label kit that came with the Interface Manager, choose the appropriate labels (designating slot, bus and drive number) and attach one label to each end of the SCSI cable. 2. BEFORE installing the interface card, plug a SCSI cable into the new interface card. DO NOT install the interface card at this time. 3.
Note The upper right LED will turn green on the interface card long before the interface card is ready to communicate with the RMC. It may takes several minutes before the interface card is ready to report its status back to the RMC. 11. Wait until the interface card boots up and reports its status to the RMC. The upper right LED will turn green on the interface card long before the interface card is ready to communicate with the RMC.
Changing a Fibre Channel Interface Card Configuration Using Telnet The Telnet interface can be used to change several parameters that control how the Interface Manager performs tasks. These parameters are found in the Fibre Channel Configuration menu. To get to the Fibre Channel Configuration menu, do the following: 1. Log into the Interface Manager using a Telnet session as described in Accessing Telnet on page 38. 2. Select [3] from the Main menu. 3. Select [2] from the Interface Card menu.
When these parameters are changed by the Telnet interface, the request to change them is immediately sent to the Fibre Channel interface card that has been selected using menu [Item 1]. However, the new setting does not take effect until the power is cycled on the Interface Manager or until the interface card is rebooted. The card selected can be rebooted using the Telnet interface by selecting [Item 7] in the Fibre Channel Configuration menu.
Configuration Using the Web Based Administrator Overview The remote management card allows web-based management and monitoring of your Interface Manager through a network connection. This interface allows you to monitor your IM from anywhere on the network through comprehensive and user friendly web pages. (See Figure 8.
The Interface Manager (IM) allows any standard Web browser to view and change the IM’s current configuration and operating status (see Table 8 ). Table 8 Supported Configurations Description Browsers Supported Configurations Windows 95/98/2000/NT: Internet Explorer™ 4.01 and higher, Netscape Communicator™ 4.5 and higher, and Netscape Navigator™ 4.08 and higher. HP-UX: Netscape Communicator™ 4.5 and higher and Netscape Navigator™ 4.08 and higher. Internet Explorer™ is not supported.
Accessing the Web Based Administrator To access the web based administrator, do the following: 1. Connect a 10 BaseT or 100 BaseT Ethernet cable to the back of the IM. 2. Apply power to connected SCSI and Fibre Channel devices. 3. After all the devices have gone through their power-up routines, boot up the IM. 4. Power-on the host computer. 5. If you know the IP address for the IM, open the host computer’s Web browser and enter the IP address into the address field of the Web browser.
Making Changes via the Web Interface Note An administrator’s password is required before any changes can be submitted. Select the [Apply] button to send changes from the Web browser to the IM. Some changes will not take effect until the next time the IM reboots. The IM can be forced to reboot right away by selecting the reboot option from the Operations tab. For equivalent settings available from the Telnet interface, see Configuration Using the Telnet Interface on page 38.
Note DO NOT bookmark Web interface pages with a Web browser. Because configuration information is transmitted via URLs, there is the possibility of the IM being configured with information present at the time a page was book marked. For similar reasons, it is also recommended NOT to use navigation features of the Web browser (for instance the [BACK] button) to navigate the Web interface.
Setting a Time That is Different From the Time Shown If the clock needs to be set to a time that is different from the time shown, do the following: 1. Select [Set Interface Manager date and time manually] button. 2. Type the correct time into the fields provided. 3. Select the [Apply] button. None of the fibre interface cards are adversely affected by this function, so it can be done while data is flowing through the interface cards.
Figure 10 Interface Manager Network Settings Chapter 3 Using DHCP If the DHCP system is to be used: 1. Select [Obtain network parameters automatically from a DHCP/BOOTP server] radio button. This enables the DHCP mode. 2. Select the [Apply] button to load the configuration into the RMC. These settings are not put into effect until the next power cycle or next RMC reboot.
Not Using DHCP If DHCP is not going to be used: 1. Select [Specify network parameters manually] button. 2. You can now enter the desired in the IP address field. 3. In the Subnet Mask field, enter the desired. 4. In the Gateway Address field, enter the desired. 5. Select the [Apply] button to load the configuration into the RMC.
Figure 11 Interface Manager Fibre Channel Address Modes Chapter 3 One of the advantages provided by using the HP Surestore Interface Manager is that the addressing modes on any combination of the interface cards can be modified at the same time. To change the addressing mode on the interface cards, you must: 1. First change the values shown in the Future Settings fields. 2. When all of the addresses in the Future column are correct, you can [Apply] them to all of the interface cards at once.
Hard Address Settings If you want to use the recommended Hard address settings: Caution Restarting an interface card during this process will stop any data flowing through that interface card, so any backup in progress will fail. 1. Select the [Set All Addressing Hard] button. 2. Select the [Apply] button to implement these Future settings to the appropriate Fibre Channel interface card. Only the interface cards that are marked as Restart, will have those settings take effect immediately.
Selecting Your Own Settings If you wish to select your own settings, then each interface card needs to be configured separately using the following sequence for each card: Caution Restarting an interface card during this process will stop any data flowing through that interface card, so any backup in progress will fail. 1. Choose between Hard and Soft addressing.
Placing a Fibre Channel Interface Card Off-Line Using the Web Administrator It is not necessary to remove power from the Interface Manager in order to remove an interface card from its slot. But, it is highly recommended to inform the firmware of your intention to do so. Placing the interface card Off-Line tells the firmware on the RMC, on the controller card, and on the interface card that the card is going to be removed.
Figure 12 Interface Manager Interface Card Replacement Chapter 3 5. Select the [Put Off-Line] button. 6. The Enter Administrator Password window will appear. You will need to enter the Interface Manager administrative password to continue (see Figure 13).
7. A Current Status window will pop-up showing you the card is being placed off-line. When the card is off-line, a second window will pop-up and show you that the card has successfully been placed off-line. 8. Select the [Close] button (see Figure 14). 9. Figure 14 66 When the upper right LED on the card turns yellow, then you can remove the card.
Placing a Fibre Channel Interface Card On-Line Using the Web Administrator Note An administrator’s password is required before any changes can be submitted. To replace an interface card that has been removed, do the following (see Figure 15): 1. BEFORE installing the interface card into the Interface Manager, attach the SCSI cable that was removed from the old card, to the correct bus on the new card, based on the connections printed on the cable label that is attached to the SCSI cable. 3.

SAN Environments 4 Chapter Overview This chapter contains information on the following: ■ Installation and Configuration on page 78 ■ Omniback Configuration on page 81 ■ HP-UX Configuration on page 85 ■ Windows Configuration on page 92 ■ Solaris Configuration on page 94 ■ Switch Configuration on page 95 SAN Environments 77
Installation and Configuration This section explains how to install and configure the HP Surestore Interface Manager within HP SAN backup solutions. Basic knowledge about installing and configuring tape libraries, Host Bus Adapters (HBAs), and software in a non-SAN configuration is required.
Figure 18 Sample Standard SAN Configuration Chapter 4 Chapter 4 SAN Environments 79
Figure 19 80 Sample Expanded SAN Configuration SAN Environments Chapter 4
Omniback Configuration SAN configurations require Omniback II v3.5 or higher. In addition, you must make the following configuration changes. 1. Open the Device & Media Management screen shown in Figure 20 by pressing the [Device & Media] button on the Omniback II Main screen that appears when you first start up Omniback. (On Windows servers, this is a drop-down menu.
2. From the Device & Media Management screen select: Edit -> Create -> SCSI-II Library Configure the library and drives so all nodes on the SAN can share them: — Configure a single tape library — Control the robotic arm from a single server, such as the cell server — Do not check the SCSI Reserve/Release box (see Figure 21) Figure 21 Logical Device Editor - SCSI-II Library 3. Configure each tape drive for each host that will access it.
Figure 22 Logical Device Editor - Drive 5. Select the [Advanced Options...] button to bring up the Logical Device Advanced Options screen shown in Figure 23 on page 84. — Verify that SCSI Reserve/Release is NOT checked. This feature is meant to be used in place of the Lock Name or in conjunction with other software applications sharing the same tape libraries. Multiple applications on the same SAN are not supported.
Figure 23 Logical Device - Advanced Options Note 84 SAN Environments For optimized performance when configuring hosts with multiple HBAs, use only one path per tape drive and distribute the tape drives across the HBAs. For additional information see HP-UX Configuration on page 85.
HP-UX Configuration Use one of the Fibre Channel cards listed in Table 5 on page 20. You must also install the fabric driver for the appropriate platform. Configure a single path for each tape drive. The device files must be manually selected or created, and configured properly in the software. In Figure 24 on page 86, ten tape drives are configured from the HP-UX host. The following 'ioscan' shows the paths and the corresponding device files. Note Always use the latest release of fabric drivers.
Figure 24 86 Sample ioscan Output SAN Environments Chapter 4
1. Set the static kernel tunable parameter st_ats_enabled to OFF (0). This can be done from the Kernel Configuration window of HP-UX system administration tool (SAM) shown in Figure 25 and requires a kernel rebuild and system reboot. When this parameter is enabled an implicit SCSI reserve and release is performed during the open and close sequence in the tape driver. This default was originally designed for ATS services with MC/ServiceGuard.
There are two ways to disable the dm_stape monitor while keeping the Event Monitoring System enabled. — Stop the dm_stape process — Prevent dm_stape from polling Note To completely disable event monitoring, run /etc/opt/resmon/ lbin/monconfig and select [(D) Disable Monitoring]. When event monitoring is shut down in this fashion, all monitors will be shut down as well. The monconfig utility is also used to disable individual event monitors.
d. Make a list of all the monitors and monitoring requests that have SCSI_tape listed. (You modify these in the next step.) e. Delete all monitoring requested for “SCSI_tape”. Use the [modify] command: — Type [M]. The tool displays a list of all monitoring requests and prompts for a number of the request to change. — Type the number of the request to modify. The tool displays a list of all the monitors for that request and prompts for the monitor(s) to modify.

Troubleshooting 5 Chapter Overview This chapter contains information on the following: ■ Troubleshooting on page 98 ■ Operation Indicators on page 99 ■ Problem - Solution on page 107 Troubleshooting 97
Troubleshooting This section is provided to help guide the user through some of the basic methods of identifying faults in the setup and configuration of the Interface Manager (IM). Most problems are found in the initial installation. In general, it is wise to check all connections and review the configuration before proceeding with further trouble analysis.
Operation Indicators The cards in the Interface Manager consist of the remote management card (RMC), controller card, and Fibre Channel interface cards. Each card has LED indicators for monitoring overall status. Table 11 Remote Management Card LEDs 1) Ready LED Color Description Yellow Powering up, failed power-on test, or fatal error was detected during operation. Flashing Yellow Attempting DHCP address assignment Green Card passed power-on test. Card ready.
Table 12 LVDS Controller Card LEDs 1) Controller LED Color Description Flashing Green Controller needs firmware. Yellow In the process of powering up. Yellow flash Controller failed power-on test. Green Ready. 2) SCSI LED 100 Troubleshooting Color Description Green No bus connected or lowvoltage differential SCSI bus connected. Flashing Green Single-ended SCSI bus attached. SCSI performance reduced. Yellow High-voltage differential SCSI bus connected. Configuration error.
Table 13 High Performance Fibre Channel Interface LEDs 1) Activity LED Color Description Flashing Green Indicates transmission activity by the Fibre Channel interface. 2) Link LED Color Description Green Indicates valid Fibre Channel connection. Yellow Fibre Channel interface is being reset.

Off DC output is outside of specified limit. 2) AC Input LED 102 Troubleshooting Color Description Green AC input is within the specified limit. Off AC input is outside of specified limit.
Basic Verification LED Indicators ■ The power supply unit LEDs turn green when power is applied to the IM. Lack of power suggests the IM may be turned off, a power supply problem, or an internal problem with the interface manager. The LEDs on both power supplies should be green, if not, reseat the individual power supply units. ■ The Activity LED on each Fibre Channel card shows Fibre Channel activity when lit.
connecting to a LVDS card, but the bus data transfer performance will be poor. Do not connect a SE SCSI drive into a HVDS card. ■ Device ID - Each device on a SCSI bus must have a unique ID. ■ Cabling - Check SCSI cables to verify they are functional. SCSI rules for total length, distance between devices, and stub length must be adhered to. Connections should also be checked and reseated if necessary.
Verify Device Recognition in HP-UX 1. Execute an ioscan command 2. The ioscan should list each tape drive and the robotics controller. (See Figure 29.
Verify Configuration A number of configuration changes may result in an invalid configuration. If you are in doubt about the configuration, restore the IM to the factory default configuration, and configure the IM one step at a time to verify the functionality of the configuration as changes are made. Verify Devices It may be useful to connect the SCSI target devices you are attempting to use to the native SCSI interface to verify that the devices are functional.
Problem - Solution This section describes potential problems and solutions. If you are unable to diagnose and solve a problem using these guidelines, contact an HP service representative or your sales representative. By using these suggested procedures, you can determine in advance some of the information that a service technician will need.
Problem: Cannot Turn on the Interface Manager If the IM will not power on, use the following procedure to diagnose the problem: 1. Verify that all power connections, breakers, and switch settings are powered-on and are set correctly. 2. Confirm that the power indicator on the power supplies are illuminated green. If not green, the IM is inoperable, and further diagnostic procedures cannot be performed. 3. Contact the sales representative or an HP service representative.
Terminate the SCSI bus on both ends, and only at the ends of the bus. By default, the IM provides internal termination at the IM end of each SCSI bus. Check each terminator and connector for bent pins. — Bus Type: The IM can contain any combination of two types of Fibre Channel interface cards. The card model number A4674A has hardware for LVDX SCSI buses. The card model number A4673A has hardware for HVDS SCSI buses.
— Confirm that the library is visible in the SCSI adapters folder of the control panel. — Confirm that there are no error indicators illuminated on the front panel of the library. Problem: Cannot Confirm Connection Through a Fibre Channel Switch 1. Check the LED indicators on each switch port. — Steady green indicates that the port is online (connected with a device over FC). — Flickering green indicates frames are being transferred through the port.
IM provides internal termination at the end of each SCSI bus. Check each terminator and connector for bent pins. — Bus Type: The IM can contain any combination of two types of Fibre Channel interface cards. The card model number A4674A has hardware for LVDS SCSI buses. The card model number A4673A has hardware for HVDS SCSI buses. Single-ended (SE) SCSI is supported by connecting to a LVDS card, but the bus data transfer performance will be poor. Note Do not connect a SE SCSI drive into a HVDS card.
— Verify IM configurations: Configuration changes may result in an invalid configuration. Try the default IM configurations settings, as they have been chosen to work in most cases. If you are in doubt about the configuration, refer to Chapter 3. If this procedure fails, contact an HP service representative.

Fibre Channel Interface and Commands B Download Commands Upgrade Firmware The upgrade firmware (WRITE_BUFFER)) command is used to transfer firmware to the Interface Manager over Fibre Channel. Multiple upgrade firmware commands will be required to accomplish the total transfer. All write commands except the final write, will have the 3-bit mode field set to 0x06. The last write command in the sequence will have the mode field bits set to 0x07 to signify the end of transfer.
