Chapter 3 Operation This chapter provides basic operating instructions, including powering up the system, booting, and operating system installation. Note that your choice of operating system has already been installed at the factory; this information is provided so that should you decide to change operating systems, you may. It also provides information about updating firmware.
3.1 Powering Up the System To power up the system, press the On/Off button to the On position.
Power up the system by pressing in the On/Off button (see Figure 3–1). Testing begins, and screen text similar to that in Example 3-1 displays (if the console terminal is a serial terminal connected to the COM1 port), along with status messages in the control panel display. If the console terminal is a graphics monitor, only the last few lines of the power-up display print. See Section 3.2 for more information.
3.2 Power-Up Display The entire power-up display prints to a serial terminal (if the console environment variable is set to serial); the last several lines print to either a serial terminal or a graphics monitor. Power-up status also displays on the control panel display.
➊ ➋ Memory size is determined. ➌ The SRM console banner and prompt are printed. (The SRM prompt is shown in this manual as P00>>>. It can, however, be P01>>>. The number indicates the primary processor.) If the auto_action environment variable is set to boot or restart and the os_type environment variable is set to unix or openvms, the DIGITAL UNIX or OpenVMS operating system boots. The PCI bridges and attendant buses (indicated as IODn by the console) are probed and the devices are reported.
3.3 Booting DIGITAL UNIX ® DIGITAL UNIX can be booted from a local disk or a remote disk through an Ethernet connection.

Example 3–8 Installing OpenVMS (Continued) Installing required known files... Configuring devices... **************************************************************** You can install or upgrade the OpenVMS Alpha operating system or you can install or upgrade layered products that are included on the OpenVMS Alpha operating system CD-ROM. You can also execute DCL commands and procedures to perform "standalone" tasks, such as backing up the system disk.
3.7 Booting Windows NT Microsoft Windows NT is started from the AlphaBIOS Boot screen. Figure 3–2 AlphaBIOS Boot Screen AlphaBIOS Setup Display System AlphaBIOS Upgrade… Hard Disk Setup… CMOS Setup… Network Setup… Install Windows NT Utilities About AlphaBIOS… 8 Press ENTER to install Windows NT.
Two SRM environment variables must be set properly for Windows NT to boot. The setting of the SRM os_type environment variable determines if AlphaBIOS is loaded and started on reset and power-up. If os_type is set to nt, after the power-up display the SRM console is loaded and started, and it then loads and starts the AlphaBIOS console. AlphaBIOS must be running before Windows NT can be booted. Windows NT requires a graphics monitor as its console.
3.8 Installing Windows NT Windows NT is installed from the CD-ROM. Insert the CD-ROM into the drive, start AlphaBIOS Setup, select the menu item Install Windows NT, and follow the prompts. Figure 3–3 Installing Windows NT AlphaBIOS Setup Display System AlphaBIOS Upgrade… Hard Disk Setup… CMOS Setup… Network Setup… Install Windows NT Utilities About AlphaBIOS… 8 Press ENTER to install Windows NT.
Windows NT requires a partitioned and formatted hard disk drive. If your drive is not partitioned or formatted, follow the instructions in Section 3.10 before installing the Windows NT operating system. Up to three versions of Windows NT can be resident in a system at one time. If this is a new Windows NT installation, start with this procedure: 1. Use CMOS Setup to set the system date and time: start AlphaBIOS Setup, select CMOS Setup, and press Enter. 2.
3.9 Switching Between Operating Systems The system supports the use of multiple operating systems on different system and data disks not in the machine at the same time; that is you can have a set of disks for each operating system. CAUTION: This operation is not for the faint hearted especially if you have a shadow system disk and shadow arrays. The file structures of the three operating systems are incompatible.
3.9.2 Switching to DIGITAL UNIX or OpenVMS Use the following procedure. 1. Shut down the operating system and power off the system. 2. Remove and mark the physical location of each disk in the system. 3. Either place blank disks or your DIGITAL UNIX or OpenVMS disk set into the system. No matter which disk set you are placing into the system, be sure that each disk is placed in the same physical location from which it was removed. 4. Power on the system. 5.
3.10 Updating Firmware Start the Loadable Firmware Update (LFU) utility by issuing the lfu command at the SRM console prompt, booting it from the CD-ROM while in the SRM console, or selecting Update AlphaBIOS in the AlphaBIOS Setup screen. Example 3–9 Starting LFU from the SRM Console P00>>> lfu ***** Loadable Firmware Update Utility ***** Select firmware load device (cda0, dva0, ewa0), or Press to bypass loading and proceed to LFU: cda0 . . .
Use the Loadable Firmware Update (LFU) utility to update system firmware. You can start LFU from either the SRM console or the AlphaBIOS console. • From the SRM console, start LFU by issuing the lfu command (see Example 3–9). Also from the SRM console, LFU can be booted from the Alpha CD-ROM (V5.4 or later), as shown in Example 3–10. • From the AlphaBIOS console, select Update AlphaBIOS from the AlphaBIOS Setup screen (see Figure 3–4). A typical update procedure is: 1. Start LFU. 2.
3.10.1 Updating Firmware from the CD-ROM Insert the Alpha CD-ROM, start LFU, and select cda0 as the load device. Example 3–11 Updating Firmware from the CD-ROM ***** Loadable Firmware Update Utility ***** Select firmware load device (cda0, dva0, ewa0), or Press to bypass loading and proceed to LFU: cda0 ➊ Please enter the name of the options firmware files list, or Press to use the default filename [AS1400FW]: AS1400CP ➋ Copying Copying Copying Copying AS1400CP from DKA500.5.0.1.
➊ Select the device from which firmware will be loaded. The choices are the internal CD-ROM, the internal floppy disk, or a network device. In this example, the internal CD-ROM is selected. ➋ Select the file that has the firmware update, or press Enter to select the default file. The file options are: AS1400FW (default) SRM console, AlphaBIOS console, and I/O adapter firmware. AS1400CP SRM console and AlphaBIOS console firmware only. AS1400IO I/O adapter firmware only.
Example 3–11 Updating Firmware from the CD-ROM (Continued) UPD> update * ➎ WARNING: updates may take several minutes to complete for each device. Confirm update on: AlphaBIOS AlphaBIOS [Y/(N)] y DO NOT ABORT! Updating to V6.0-3... Verifying V6.0-3... UPD> exit 3-30 ➏ DO NOT ABORT! Updating to V6.40-1... Verifying V6.40-1... PASSED. Confirm update on: srmflash srmflash PASSED.
➎ The update command updates the device specified or all devices. In this example, the wildcard indicates that all devices supported by the selected update file will be updated. ➏ For each device, you are asked to confirm that you want to update the firmware. The default is no. Once the update begins, do not abort the operation. Doing so will corrupt the firmware on the module. ➐ The exit command returns you to the console from which you entered LFU (either SRM or AlphaBIOS).
3.10.2 Updating Firmware from Floppy Disk — Creating the Diskettes Create the update diskettes before starting LFU. See Section 3.10.3 for an example of the update procedure. Table 3–1 File Locations for Creating Update Diskettes on a PC Console Update Diskette I/O Update Diskette AS1400FW.TXT AS1400IO.TXT AS1400CP.TXT TCREADME.SYS TCREADME.SYS CIPCA315.SYS TCSRMROM.SYS DFPAA310.SYS TCARCROM.SYS KZPAAA11.
Example 3–12 Creating Update Diskettes on an OpenVMS System Console update diskette $ $ $ $ $ $ $ $ $ $ $ $ $ $ inquire ignore "Insert blank HD floppy in DVA0, then continue" set verify set proc/priv=all init /density=hd/index=begin dva0: tcods2cp mount dva0: tcods2cp create /directory dva0:[as1400] copy tcreadme.sys dva0:[as1400]tcreadme.sys copy AS1400fw.txt dva0:[as1400]as1400fw.txt copy AS1400cp.txt dva0:[as1400]as1400cp.txt copy tcsrmrom.sys dva0:[as1400]tcsrmrom.sys copy tcarcrom.
3.10.3 Updating Firmware from Floppy Disk — Performing the Update Insert an update diskette (see Section 3.10.2) into the floppy drive. Start LFU and select dva0 as the load device.
➊ Select the device from which firmware will be loaded. The choices are the internal CD-ROM, the internal floppy disk, or a network device. In this example, the internal floppy disk is selected. ➋ Select the file that has the firmware update, or press Enter to select the default file. When the internal floppy disk is the load device, the file options are: AS1400CP (default) SRM console and AlphaBIOS console firmware only. AS1400IO I/O adapter firmware only.
Example 3–13 Updating Firmware from the Floppy Disk (Continued) UPD> update pfi0 ➍ WARNING: updates may take several minutes to complete for each device. Confirm update on: pfi0 [Y/(N)] y ➎ DO NOT ABORT! Updating to 3.10... Verifying to 3.10... PASSED.
➍ ➎ The update command updates the device specified or all devices. ➏ The lfu command restarts the utility so that console firmware can be updated. (Another method is shown in Example 3–14, where the user specifies the file AS1400FW and is prompted to insert the second diskette.) ➐ The default update file, AS1400CP, is selected. The console firmware can now be updated, using the same procedure as for the I/O firmware.
3.10.4 Updating Firmware from a Network Device Copy files to the local MOP server’s MOP load area, start LFU, and select ewa0 as the load device.
Before starting LFU, download the update files from the Internet. You will need the files with the extension .SYS. Copy these files to your local MOP server’s MOP load area. ➊ Select the device from which firmware will be loaded. The choices are the CDROM, the internal floppy disk, or a network device. In this example, a network device is selected. ➋ Select the file that has the firmware update, or press Enter to select the default file.
Example 3–15 Updating Firmware from a Network Device (Continued) UPD> update * -all ➍ WARNING: updates may take several minutes to complete for each device. AlphaBIOS DO NOT ABORT! Updating to V6.40-1... Verifying V6.40-1... PASSED. kzpsa0 DO NOT ABORT! Updating to A11 ... Verifying A11... PASSED. kzpsa1 DO NOT ABORT! Updating to A11 ... Verifying A11... PASSED. srmflash DO NOT ABORT! Updating to V6.0-3... Verifying V6.0-3... PASSED.
➍ The update command updates the device specified or all devices. In this example, the wildcard indicates that all devices supported by the selected update file will be updated. Typically LFU requests confirmation before updating each console’s or device’s firmware. The -all option eliminates the update confirmation requests. ➎ The exit command returns you to the console from which you entered LFU (either SRM or AlphaBIOS).
3.10.5 LFU Commands The commands summarized in Table 3–2 are used to update system firmware. Table 3–2 LFU Command Summary Command Function display Shows the physical configuration of the system. exit Terminates the LFU program. help Displays the LFU command list. lfu Restarts the LFU program. list Displays the inventory of update firmware on the selected device. readme Lists release notes for the LFU program. update Writes new firmware to the module.
display The display command shows the physical configuration of the system. Display is equivalent to issuing the SRM console command show configuration. Because it shows the slot for each module, display can help you identify the location of a device. exit The exit command terminates the LFU program, causes system initialization and testing, and returns the system to the console from which LFU was called. help The help (or ?) command displays the LFU command list, shown below.
list The list command displays the inventory of update firmware on the CD-ROM, network, or floppy. Only the devices listed at your terminal are supported for firmware updates. The list command shows three pieces of information for each device: • Current Revision — The revision of the device’s current firmware • Filename — The name of the file used to update that firmware • Update Revision — The revision of the firmware update image readme The readme command lists release notes for the LFU program.
3.11 Hard Disk Partitioning for Windows NT The recommended hard disk partition on the first hard disk in your system is: partition 1 should be 6 megabytes less than the total size of the drive (this large partition holds the operating system and the application and data files) and partition 2 should be the remaining 6 megabytes (this small partition holds only the few files necessary for your computer to boot).
No Hard Disks Found When you start hard disk setup, if you receive a “No hard drives were found connected to your computer” message, it means that AlphaBIOS could not locate a hard drive. The likely conditions that cause this error are: • Cable not connected to either the disk or controller. The cable may have worked loose from the connector on the controller or disk drive. Check the cable connections, making sure the cable connectors are fully seated. • No power to the drive.
3.11.3 How AlphaBIOS Works with System Partitions If you are installing Windows NT for the first time, AlphaBIOS will determine that a system partition has not been defined when you select Install Windows NT in the AlphaBIOS Setup screen (see Figure 3–5). When this occurs, AlphaBIOS searches for all FAT partitions on the system. If only one FAT partition exists, AlphaBIOS designates that FAT partition as the system partition and continues with the Windows NT installation.
3.12 Using the Halt Button Use the Halt button to halt the DIGITAL UNIX or OpenVMS operating system when it hangs, clear the SRM console password, or force a halt assertion, as described in Section 3.12. Using Halt to Shut Down the Operating System You can use the Halt button if the DIGITAL UNIX or OpenVMS operating system hangs. Pressing the Halt button halts the operating system back to the SRM console firmware.
3.13 Halt Assertion A halt assertion allows you to disable automatic boots of the operating system so that you can perform tasks from the SRM console. Under certain conditions, you might want to force a “halt assertion.” A halt assertion differs from a simple halt in that the SRM console “remembers” the halt. The next time you power up, the system ignores the SRM power-up script (nvram) and ignores any environment variables that you have set to cause an automatic boot of the operating system.
If you enter the RCM haltin command when Windows NT or AlphaBIOS is running, the interrupt is ignored. However, you can enter the RCM haltin command followed by the RCM reset command to force a halt assertion. Upon reset, the system powers up to the SRM console, but the SRM console does not load the AlphaBIOS console.
Chapter 4 SRM Console The SRM console is the command line interface that supports the DIGITAL UNIX and OpenVMS operating systems. The SRM console is used to bootstrap the operating system, configure and test the system hardware, examine system options for errors, and set or change environment variables. This chapter describes the SRM commands and environment variables.
4.1 Invoking the SRM Console When a system is powered up, the SRM console runs and either remains running or passes control to another console or an operating system. If the system is already running, invoke the SRM console by shutting down the operating system or by pressing the Halt button on the control panel.
4.2 Command Summary The SRM (Alpha System Reference Manual) console is a command line interface used when the operating system is either DIGITAL UNIX or OpenVMS. Console commands enable the user to examine and modify the system state. Table 4-1 gives the most commonly used SRM console commands. Table 4-2 gives the syntax for the console commands. Table 4-3 gives special characters you can use in console mode.
Table 4-1 Summary of SRM Console Commands (Continued) Command Function more Displays a file one screen at a time. prcache Utility that initializes and displays status of the optional PCI NVRAM device. set envar Sets or modifies the value of an environment variable. set host Connects to an MSCP DUP server on a DSSI device. set password Sets the console password for the first time or changes an existing password. set secure Enables secure mode without requiring a restart of the console.
Table 4-2 Syntax for SRM Console Commands Parameter Attribute or Action Length Up to 255 characters, not including the terminating carriage return or any characters deleted as the command is entered. A command longer than 80 characters and without the backslash character (see Table 4-3) causes display of an error message. Case Upper- or lowercase characters can be used for input. Characters are displayed in the case in which they are entered.
Table 4-3 Special Characters for SRM Console Character Function Return or Enter Terminates a command line. No action is taken on a command until it is terminated. If no characters are entered and this key is pressed, the console just redisplays the prompt. Backslash (\) Continues a command on the next line. Must be the last character on the line to be continued. Delete Deletes the previous character. Help By itself, displays first-level help.
Table 4-3 Special Characters for SRM Console (Continued) Character Function Ctrl/R Redisplays the current line. Deleted characters are omitted. This command is useful for hardcopy terminals. Ctrl/S Suspends output to the console terminal until Ctrl/Q is entered. Cleared by Ctrl/C. Ctrl/U Deletes the current line. * Wildcarding for commands such as show. "" Double quotes enable you to denote a string for environment variable assignment.
4.3 Displaying the System Configuration Several commands are used to display the system configuration: show config, show cpu, show device, show memory, show pal, show power, and show version. Example 4–1 Show Config Command P00>>> show config AlphaPC 264DP 500 MHz SRM Console: V5.4-x PALcode: OpenVMS PALcode V1.42-32, Digital UNIX PALcode V1.40-35 Processors CPU 0 Alpha 21264-3 500 MHz SROM Revision: V1.82 Bcache size: 4 MB CPU 1 Alpha 21264-4 500 MHz SROM Revision: V1.

Example 4–7 Show Version Command P00>>> show version version P00>>> V5.4-x NOV 20 1998 13:59:28 The show version command displays the version of the SRM console program that is installed on the system.
4.4 Creating a Power-Up Script The system comes with a special nonvolatile file named “nvram” that is stored in EEROM. Nvram is a user-created power-up script (set of commands) that is always invoked during the power-up sequence. Use the SRM edit command to create or alter the nvram script.
Editing the Nvram Script You can create an nvram script to include any commands you want the system to execute at power-up. You create and edit the nvram script using the SRM edit command. With edit, lines may be added, overwritten, or deleted. The syntax is: edit file file is the name of the file to be edited. The editing commands are: help Displays the brief help file. list Lists the current file prefixed with line numbers. renumber Renumbers the lines of the file in increments of 10.
4.5 Booting the Operating System The boot command is used to boot the operating system. Example 4–10 Boot Command P00>>> b dka200 (boot dka200.2.0.7.1 -flags 0,0) block 0 of dka200.2.0.7.1 is a valid boot block reading 893 blocks from dka200.2.0.7.
The boot command initializes the processor, loads a program image from the specified boot device, and transfers control to that image. The syntax is: boot [-file filename] [-flags [value]] [-halt] [-protocols enet_protocol] [boot_dev] -file filename The boot file. -flags [value] Specifies additional information to the loaded image or operating system. In DIGITAL UNIX, specifies boot flags. In OpenVMS, specifies system root number and boot flags.
4.6 Configuring the System 4.6.1 Configuring DSSI The set host command is used for system configuration when a DSSI device is in the system. Example 4–11 Set Host Command P00>>> show device dka0.0.0.7.1 dka100.1.0.7.1 dka200.2.0.7.1 dka300.3.0.7.1 dka500.5.0.7.1 dkb0.0.0.2000.1 dkb200.2.0.2000.1 dkb400.4.0.2000.1 dkc100.1.0.2001.1 dkc300.3.0.2001.1 dua101.3.0.8.0 dua103.1.0.8.0 dua110.0.0.8.0 dua240.2.0.8.0 dva0.0.0.0.0 ewa0.0.0.2002.1 pka0.7.0.7.1 pkb0.7.0.2000.1 pkc0.7.0.2001.1 pua0.7.0.8.

4.7 Testing the System The test command runs firmware diagnostics for components of the system. This command is used to test Windows NT systems as well as DIGITAL UNIX and OpenVMS systems. Example 4–14 Test Command P00>>> test System test, runtime 1200 seconds Type ^C if you wish to abort testing once it has started Default zone extended at the expense of memzone.
The test command runs console-based exercisers for devices in the system. Testing can be aborted by Ctrl/C. NOTE: If you are running the Microsoft Windows NT operating system, switch from AlphaBIOS to the SRM console in order to enter the test command. Select DIGITAL UNIX Console (SRM) or OpenVMS Console (SRM) from the Advanced CMOS Setup of the AlphaBIOS console screen, save the setting by pressing the F10 key, and then reset the system.
4.8 Making the System Secure Placing the console in secure mode ensures that unauthorized persons cannot gain access to the system. The commands for console security are set password, clear password, and set secure. The login command turns off security features during the current console session.
Example 4–16 Set Secure Command P00>>> set secure # In this example a password # has been set. Console is secure. Please login. P00>>> b dkb0 Console is secure - parameters are not allowed. P00>>> login Please enter the password: # Password is not echoed. P00>>> b dkb0 (boot dkb0.0.0.3.1) . . P00>>> set secure # Password has not been set. Secure not set. Please set the password. P00>>> The set secure command enables secure mode without requiring a restart of the console.
Example 4–17 Login Command P00>>> login # System is not in secure # mode. Secure not set. Please set the password. P00>>> P00>>> login Please enter the password: P00>>> # System is in secure mode. # Password is not echoed. P00>>> login Please enter the password: # System is in secure mode. # Incorrect password is # entered. Invalid password P00>>> The login command turns off the security features, enabling access to all SRM console commands during the current session.
If you have forgotten the current password, clear the password as follows: • From the Local Console Terminal 1. Enter the login command: P00>>> login 2. At the Enter Password: prompt, press the Halt button, then press the Return key. The password is now cleared and the console cannot be put into secure mode unless a new password is set. • From the RCM 1. Enter the login command: P00>>> login 2. At the Enter Password: prompt, enter the RCM escape sequence. 3.
Example 4–18 Clear Password Command P00>>> clear password Please enter the password: # Password is not echoed. Password successfully cleared. P00>>> P00>>> clear password Please enter the password: Console is secure P00>>> # Invalid password entered. The clear password command clears the password environment variable, setting it to zero. This command is used when you want access to all the SRM console commands, but the system is in secure mode.
4.9 Stopping and Starting CPUs The halt and continue commands are used to stop and continue a program on the specified CPU.
halt (or stop) The halt (or stop) command stops program execution on a secondary CPU that is still running a booted program. The syntax is: halt (or stop) processor_number processor_number is the logical CPU number displayed by the show cpu command. continue The continue command resumes program execution on the specified processor or on the primary processor if none is specified. The processor begins executing instructions at the address that is currently in the program counter (PC).
4.10 Updating Firmware The lfu command is used to update firmware from the SRM console prompt. Example 4–20 Lfu Command P00>>> lfu ***** Loadable Firmware Update Utility ***** Select firmware load device (cda0, dva0, ewa0), or Press to bypass loading and proceed to LFU: cda0 Please enter the name of the options firmware files list, or Press to use the default filename [AS1400FW]: AS1400CP Copying Copying Copying Copying AS1200CP from DKA500.5.0.1.1 . [as1200]TCREADME from DKA500.5.0.1.
Example 4–20 Lfu Command (Continued) UPD> list Device Fsb Nt Pkx0 Srm Pua Current Revision 3.1-x 5.68 A11 5.4-x A214 Filename fsb_fw nt_fw kzpsa_fw srm_fw cipca_fw Update Revision 3.x 5.xx A11 5.4-xx A2xx UPD> update * WARNING: updates may take several minutes to complete for each device. Confirm update on: AlphaBIOS AlphaBIOS DO NOT ABORT! Updating to V6.40-1... Verifying V6.40-1... PASSED. Confirm update on: srmflash srmflash [Y/(N)] y [Y/(N)] y DO NOT ABORT! Updating to V6.0-3... Verifying V6.
4.11 Forcing a System Crash Dump The crash command forces a crash dump to the selected device on running DIGITAL UNIX and OpenVMS systems. The command has no effect on systems running Windows NT. Example 4–21 Crash Command P00>>> crash CPU 0 restarting DUMP: 401408 blocks available for dumping. DUMP: 38535 required for a partial dump. DUMP: 0x805001 is the primary swap with 401407, start our last 38534 : of dump at 362873, going to end (real end is one more, for header) DUMP.
4.12 Using Environment Variables Environment variables pass configuration information between the console and the operating system. Their settings determine how the system powers up, boots the operating system, and operates. You issue an init command to activate a new environment variable.
set envar The set command sets or modifies the value of an environment variable. It can also be used to create a new environment variable if the name used is unique. Environment variables are used to pass configuration information between the console and the operating system. The setting of these variables determines how the system powers up, boots the operating system, and operates. The syntax is: set [-default] envar value -default Restores an environment variable to its default setting.
Example 4–23 Creating a User-Defined Environment Variable P00>>> edit nvram editing ‘nvram’ 0 bytes read in *10 set mopv3_boot 1 *exit 17 bytes written out to nvram P00>>> In Example 4–23 the nvram script is edited so that an environment variable called “mop3_boot” is created and set to 1 on each power-up. By default, MOP boots send four MOP V4 requests before defaulting to MOP V3. This user-created environment variable forces the SRM console to bypass MOP V4 requests.
4.13 Depositing and Examining Data The deposit command stores data in a specified location. The examine command displays the contents of a memory location, a register, or a device. Example 4–24 Deposit Command P00>>> dep -b -n 1ff pmem:0 0 # # P00>>> d -l -n 3 vmem:1234 5 # # # # P00>>> d -n 8 r0 ffffffff # # P00>>> d -l -n 10 -s 200 pmem:0 # # # P00>>> d -l pmem:0 0 # # P00>>> d + ff # # P00>>> d scbb 820000 # Clear first 512 bytes of physical memory.
Example 4–25 Examine Command (Continued) grp: grp: grp: grp: grp: grp: grp: 20 28 30 38 40 48 50 ( ( ( ( ( ( ( R4) R5) R6) R7) R8) R9) R10) 0000000000005000 000000000FFFE000 00000003F8000C00 0000000053F761AE 0000010000000000 00000003F7800100 00000000000C7FFC P00>>> examine pmem:400EC # Examine physical memory. pmem: 400EC A49D0078A47D0070 deposit The deposit command stores data in the location specified.
-o Defines data size as octaword. -h Defines data size as hexword. -d Instruction decode (examine command only) -n value The number of consecutive locations to modify. -s value The address increment size. The default is the data size. space: Device name (or address space) of the device to access. address Offset within a device to which data is deposited. Can be: data dev_name A device name. fpr- name The floating-point register set; name is F0 to F31.
4.14 Reading a File The more command displays a file one screen at a time. Example 4–26 More Command P00>>> more el #Display the contents of the #SRM console’s event log one #screen at a time. P00>>> help * | more #Display the contents of online #help one screen at a time. The more command is similar to that used in the MS-DOS and UNIX operating systems. It is useful for displaying output that scrolls too quickly to be viewed.
4.15 Initializing the System The initialize command resets the system and executes the power-up tests. Example 4–27 Initialize Command P00>>> init Initializing...
Total Bad Pages = 0 Total Good Memory = 1408 MBytes AlphaServer DS20 500 MHz Console V5.4-xx, Nov 5 1998 11:18:30 P00>>> The initialize command resets the system. Issuing this command is equivalent to pressing the Reset button. The syntax is: initialize After self-tests are executed, the system autoboots unless one of the following is true: • A halt assertion condition exists (see Section 3.12). • The auto_action environment variable is set to halt.
4.16 Finding Help The help command displays basic information about a command. Example 4–28 Help Command P00>>> help set NAME set FUNCTION Set an option or modify the value of an environment variable. SYNOPSIS set
4.17 Switching from SRM to AlphaBIOS Console It is necessary to switch to the AlphaBIOS console to run configuration utilities. To switch from SRM to AlphaBIOS, issue the alphabios command. Example 4–29 Switching to the AlphaBIOS Console P00>>> alphabios The alphabios command loads and starts the AlphaBIOS console. This is necessary for running AlphaBIOS-based utilities (such as the RAID configuration utility).
4.18 Environment Variable Summary Environment variables pass configuration information between the console and the operating system. Their settings determine how the system powers up, boots the operating system, and operates. Environment variables are set or changed with the set envar command and returned to their default values with the clear envar command. Their values are viewed with the show envar command. Table 4-6 lists the environment variables. Detailed descriptions follow.
Table 4-6 Environment Variable Summary (Continued) Environment Variable Function ocp_text Overrides the default OCP display text with specified text. os_type Specifies the operating system. Valid entries are: openvms, unix, and nt. password A password stored in the NVRAM used to secure the console. pci_parity Disables or enables parity checking on the PCI bus. pk*0_fast Enables fast SCSI mode. pk*0_host_id Specifies the default value for a controller host bus node ID.
auto_action Specifies the action the console takes any time the system powers up, fails, or resets. When the setting involves autoboot, the system boots from the default boot device specified by the value of the bootdef_dev environment variable. The syntax is: set auto_action value The options for value are: halt The system remains in console mode after power-up or a system crash. boot The system boots automatically when it is turned on and halts after a system failure.
boot_osflags The boot_osflags environment variable passes information to the boot command. That information is dependent on the operating system to be booted. When the operating system is DIGITAL UNIX, the syntax is: set boot_osflags flags_value The options for flags_value are: a Load operating system software from the specified boot device (autoboot). Boot to multi-user mode. i Prompt for the name of a file to load and other options (boot interactively). Boot to single-user mode.
Table 4-7 Settings for boot_osflags Bootflags (OpenVMS) Flags_Value Bit Number Meaning 1 0 Bootstrap conversationally (enables you to modify SYSGEN parameters in SYSBOOT). 2 1 Map XDELTA to running system. 4 2 Stop at initial system breakpoint. 8 3 Perform diagnostic bootstrap. 10 4 Stop at the bootstrap breakpoints. 20 5 Omit header from secondary bootstrap image. 80 7 Prompt for the name of the secondary bootstrap file. 100 8 Halt before secondary bootstrap.
console The console terminal can be either a graphics monitor or a serial terminal. The console environment variable specifies which is used. The syntax is: set console output_device The options for output_device are: graphics (default) The console terminal is a graphics monitor or a device connected to the VGA or TGA module. serial The console terminal is the device connected to the COM1 port.
ew*0_mode Sets an Ethernet controller to run an AUI, ThinWire, or twisted-pair Ethernet network. The default is auto-sense. For the fast setting, the device defaults to fast. The syntax is: set ew*0_mode value The options for value are: aui Device type is AUI. auto-sense Device type is sensed by the console. twisted-pair Device type is 10BaseT (twisted pair).
kbd_hardware_type Used only on systems with the language variant 3C (Français), this environment variable sets the keyboard hardware type as either PCXAL or LK411 and enables the system to interpret the terminal keyboard layout correctly. Whenever you change the value of kbd_hardware_type, you must reset the system by pressing the Reset button or issuing the initialize command.
ocp_text Specifies a message to display on the control panel after self-tests and diagnostics have completed. The value of ocp_text takes effect only after you reset the system by pressing the Reset button or issuing the initialize command. The syntax is: set ocp_text message The variable message can be up to 16 characters and must be enclosed in quotation marks. os_type The os_type environment variable specifies the default operating system.
password Sets or clears the console password stored in NVRAM. The syntax is: set password The password is not an argument to the set password command; the console prompts the user for the string, which must be between 15 and 30 characters. pci_parity Disables or enables parity checking on the PCI bus. Some PCI devices do not implement PCI parity checking, and some have a paritygenerating scheme in which the parity is sometimes incorrect or is not fully compliant with the PCI specification.
pk*0_host_id Sets the controller host bus node ID to a value between 0 and 7. Each SCSI bus in the system requires a controller. Buses can theoretically support up to eight devices; however, the eighth device must always be a controller. Each device on the bus, including the controller, must have a unique ID, which is a number between 0 and 7. This is the bus node ID number. On each bus, the default bus node ID for the controller is set to 7.
tt_allow_login Enables or disables login to the SRM console firmware on alternate console ports. If the environment variable console is set to serial, the primary console device is the terminal connected through the COM1 port. The command set tt_allow_login 1 enables logins through either the COM2 port or a graphics monitor. The syntax is: set tt_allow_login value The options for value are: 0 Disables login through the COM2 port or a graphics monitor.

5.7 Installing Windows NT Install Windows NT from the CD-ROM. Up to three versions of the operating system can be resident in the system at one time. Read the instructions carefully; it is easy to install the wrong CD-ROM driver. Figure 5-21 Installing Windows NT AlphaBIOS Setup Display System Configuration… AlphaBIOS Upgrade… Hard Disk Setup… CMOS Setup… Network Setup… Install Windows NT Utilities About AlphaBIOS… 8 Press ENTER to install Windows NT.
If Windows NT was installed at the factory, Windows NT setup will start automatically the first time the system powers up. NOTE: Steps 1 and 2 in the following procedure are necessary only when you are first setting up your system. On subsequent installations and upgrades, begin at step 3. Read these instructions carefully paying particular attention to step 5. 1. Use CMOS Setup to set the system date and time: start AlphaBIOS Setup, select CMOS Setup, and press Enter. 2.
5.8 Selecting the Version of Windows NT Up to three versions of Windows NT can reside on the system at one time. Select the version that will be started from the Operating System Selection Setup screen. Figure 5-22 Operating System Selections Operating System Selection Setup Windows NT Server 4.0 Windows NT Server 5.0 Boot Name: Boot File: OS Path: OS Options: INSERT DEL = New = Delete Primary Operating System Windows NT Server 4.0 Disk 0, partition 2 \os\winnt40\osloader.
NOTE: The term “operating system selection,” as it is used in this context, refers to a version of Windows NT. It does not pertain to the DIGITAL UNIX and OpenVMS operating systems. Each operating system selection is a set of information for a version of Windows NT. It describes the disk and partition containing the OSLOADER.EXE file associated with a particular operating system installation, as well as the path to the operating system itself.
5.8.1 Designating a Primary Operating System Figure 5-23 Primary Operating System AlphaBIOS 5.29 Please select the operating system to start: 1 Windows NT Server 4.0 Windows NT Server 5.0 Use and to move the highlight to your choice.

Multiple versions of Windows NT can be installed at the same time. This can be very useful in a variety of circumstancesfor example, when testing application compatibility across different versions of Windows NT. Up to three operating systems can be resident on the system. Each time you install a separate version of Windows NT, a new operating system selection is created. Although you can start any of the installed versions of Windows NT, one of them must be the primary operating system.
5.8.2 Primary Operating System and the Auto Start Option The process of setting up your operating system selections is similar to using an editor. You can make changes to your operating system selections and then either save your changes or exit without saving. Figure 5-24 Operating System Selection Setup Operating System Selection Setup Windows NT Server 4.0 2 3 4 5 1 Primary Operating System Boot Name: Windows NT Server 4.0 Boot File: Disk 0, Partition 2 \os\winnt400\osloader.
➊ Primary operating system — The OS that appears first on the AlphaBIOS Boot screen. It is also the version of the OS that automatically starts if Auto Start is selected. Any of the operating system selections can be the primary operating system. ➋ Boot name — Each boot name is associated with an operating system selection. Windows NT setup automatically creates a boot name each time you install the operating system.
➎ OS options — Lists the startup parameters passed to the operating system for an operating system selection. One example of a startup parameter is whether to start the operating system in debug mode. By default, Windows NT does not add any entries to this field. This field can be modified. ➏ Operating System Selection Setup options — You can use the options listed at the bottom of the screen to edit operating system selections.
Validate OS selection (F9 key) — Validates the fields in the currently selected OS selection. The validation routine checks that the OS loader file and OS directory fields contain valid paths and that the OSLOADER.EXE file exists in the directory specified. At the end of the validation, a dialog box is displayed describing the results of the validation. If there is an error in an OS selection, the validation routine displays a dialog box describing the component of the OS selection that is in error.
5.9 Switching from AlphaBIOS to SRM Console It is necessary to switch to the SRM console to boot DIGITAL UNIX or OpenVMS or to run firmware-based diagnostics. To switch from AlphaBIOS to the SRM console, press the Reset button on the control panel, wait 5 seconds, and press the Halt button. Alternatively, select DIGITAL UNIX (SRM) or OpenVMS (SRM) from the Advanced CMOS Setup screen and reset the system.
DIGITAL UNIX and OpenVMS are booted and firmware-based diagnostics are run from the SRM console. Follow this procedure to switch from AlphaBIOS to SRM: 1. Select CMOS Setup and press Enter. 2. In the CMOS Setup screen press F6. The Advanced CMOS Setup screen is displayed. 3. Select DIGITAL UNIX console (SRM) or OpenVMS console (SRM) and press F10. 4. The CMOS Setup screen is displayed. Press F10 to save the change. 5. Reset the system.

Start AlphaBIOS Setup by issuing the command alphabios. 2.
Chapter 6 Managing the System Remotely This chapter describes how to manage the system from a remote location using the Remote Console Manager (RCM). You can use the RCM from a console terminal at a remote location or from a local console terminal connected to the COM1 port.
6.1 RCM Overview The remote console manager (RCM) monitors and controls the system remotely. The control logic resides on the system board. The RCM is a separate console from the SRM and AlphaBIOS consoles. The SRM and AlphaBIOS firmware reside on the system board. The RCM firmware resides on the server feature module and can only be accessed through COM 1. The RCM is run from a serial console terminal or terminal emulator.
6.2 First-Time Setup To set up the RCM to monitor a system remotely, connect the modem to the COM1 port at the back of the system, configure the modem port for dial-in, and dial in.
6.2.1 Dialing In and Invoking RCM To dial in to the modem on COM1, dial the modem, and type the escape sequence to bring up the RCM. Use the hangup command to terminate the session. A sample dial-in dialog would look similar to the following: Example 6–1 Sample Remote Dial-In Dialog ATQ0V1E1S0=0 OK ATDT30167 CONNECT 9600 # RCM V2.0 RCM> ➊ ➋ ➌ Dialing In and Invoking RCM 1. Dial the number for the modem connected to the modem port. See ➊ in Example 6–1 for an example.
4. To terminate the modem connection, enter the RCM hangup command. RCM> hangup If the modem connection is terminated without using the hangup command or if the line is dropped due to phone-line problems, the RCM will detect carrier loss and initiate an internal hangup command. If the modem link is idle for more than 20 minutes, the RCM initiates an auto hangup. NOTE: Auto hangup can take a minute or more, and the local terminal is locked out until the auto hangup is completed. 6.2.
6.3 RCM Commands The RCM commands given in Table 6-1 are used to control and monitor a system remotely. Table 6-1 RCM Command Summary Command Function halt Halts the server. Emulates pressing the Halt button and immediately releasing it. haltin Causes a halt assertion. Emulates pressing the Halt button and holding it in. haltout Terminates a halt assertion created with haltin. Emulates releasing the Halt button after holding it in.
Command Conventions • • • • • The commands are not case sensitive. A command must be entered in full. You can delete an incorrect command with the Backspace key before you press Enter. If you type a valid RCM command, followed by extra characters, and press Enter, the RCM accepts the correct command and ignores the extra characters. If you type an incorrect command and press Enter, the command fails with the message: *** ERROR - unknown command *** halt The halt command halts the managed system.
help or ? The help or ? command displays the RCM firmware commands. poweroff The poweroff command requests the RCM to power off the system. The poweroff command is equivalent to pressing the On/Off button on the control panel to the off position. RCM>poweroff If the system is already powered off or if switch 3 (RPD DIS) on the switchpack has been set to the on setting (disabled), this command has no immediate effect.
quit The quit command exits the user from command mode and reconnects the serial terminal to the system console port. The following message is displayed: Focus returned to COM port The next display depends on what the system was doing when the RCM was invoked. For example, if the RCM was invoked from the SRM console prompt, the console prompt will be displayed when you enter a carriage return.
setesc The setesc command resets the default escape sequence for invoking RCM. The escape sequence can be any character string. A typical sequence consists of 2 or more characters, to a maximum of 15 characters. The escape sequence is stored in the module’s on-board NVRAM. NOTE: Be sure to record the new escape sequence. Although the factory defaults can be restored if you forget the escape sequence, this requires resetting the EN RCM switch on the RCM switchpack.
Table 6-2 RCM Status Command Fields Item Description Firmware Rev: Revision of RCM firmware. Escape Sequence: Current escape sequence to invoke RCM. Remote Access: Modem remote access state. (ENABLE/DISABLE) Temp (C): Current system temperature in degrees Celsius. RCM Power Control: Current state of RCM system power control. (ON/OFF) RCM Halt: Asserted indicates that halt has been asserted with the haltin command.
6.4 Using the RCM Switchpack The RCM operating mode is controlled by a switchpack on the server feature module located in the fan area between the system card cage and the front of the system. Use the switches to enable or disable certain RCM functions, if desired.
Figure 6-3 RCM Switches (Factory Settings) On Off 1 2 3 4 Switch Name Description 1 EN RCM Enables or disables the RCM. The default is ON (RCM enabled). The OFF setting disables RCM. 2 Reserved Reserved 3 RPD DIS Enables or disables remote poweroff. The default is OFF (remote poweroff enabled). 4 SET DEF Sets the RCM to the factory defaults. The default is OFF (reset to defaults disabled).
Uses of the Switchpack You can use the RCM switchpack to change the RCM operating mode or disable the RCM altogether. The following are conditions when you might want to change the factory settings. • Switch 1 (EN RCM)—Set this switch to OFF (disable) if you want to reset the baud rate of the COM1 port to a value other than the system default of 9600. You must disable RCM to select a baud rate other than 9600. • Switch 2 (Reserved) —Reserved. • Switch 3 (RPD DIS).
Resetting the RCM to Factory Defaults You can reset the RCM to factory settings, if desired. You would need to do this if you forgot the escape sequence for the RCM. Follow the steps below. 1. Turn off the system. 2. Unplug the AC power cords. NOTE: If you do not unplug the power cords, the reset will not take effect when you power up the system. 3. Remove the system covers. See Section 7.2. 4. Locate the RCM switchpack on the server feature module and set switch 4 to ON. 5.
6.5 Troubleshooting Guide Table 6-3 is a list of possible causes and suggested solutions for symptoms you might see. Table 6-3 RCM Troubleshooting Symptom Possible Cause Suggested Solution The local console terminal is not accepting input. Cables not correctly installed. Check external cable installation. Switch 1 on switchpack set to disable. Set switch 1 to ON. The console terminal is displaying garbage. System and terminal baud rate set incorrectly.
6.6 Modem Dialog Details This section is intended to help you reprogram your modem if necessary. Default Initialization and Answer Strings The modem initialization and answer command strings set at the factory for the RCM are: Initialization string: AT&F0EVS0=0S12=50 Answer string ATXA NOTE: All modem commands must be terminated with a character (0x0d hex). Modifying Initialization and Answer Strings The initialization and answer strings are stored in the RCM’s NVRAM.
