Booting Operations  



The following sections describe different methods of booting your system.

Booting the Operating System CD-ROM  

If you need to boot the OpenVMS Alpha operating system CD-ROM, either to perform an installation or upgrade or to perform related operations such as mounting or backing up the system disk, follow the steps in the following sections, depending on whether you are booting locally or from the InfoServer.

Booting from the Local Drive  

Boot from the local drive as follows:

  1. Insert the operating system CD-ROM into the local CD-ROM drive.
  2. At the console prompt (>>>), enter the SHOW DEVICE command so you can identify the name of the CD-ROM drive (for example, DKA400:)
  3. Enter the boot command in the following format:

    BOOT -FLAGS 0,0 source-drive

    Substitute the device name of the CD-ROM drive (as listed in the SHOW DEVICE display) for source-drive.

    For example, if the SHOW DEVICE display lists the device name of your CD-ROM drive as DKA400, enter the following command and press the Return key:
    >>> BOOT -FLAGS 0,0 DKA400

After you boot, the system displays a menu from which you can choose options to perform the following tasks:

Booting from the InfoServer  

To boot the operating system CD-ROM using the InfoServer, do the following:

  1. At the console prompt (>>>), enter the SHOW DEVICE command and scan the devices listed in the output to determine the name of the CD-ROM drive. Look for a device listed with its hardware address, as in the last line of the following example; compare this information with that provided by the table in step 2.
    >>>SHOW DEVICE
     
    dva0.0.0.1000.0    DVA0                     RX23
    dka200.2.0.5.0     DKA200                   RZ28M  1004
    dka300.3.0.5.0     DKA300                   RZ29B  0016
    dka400.4.0.5.0     DKA400                   RZ26L  442E
    ewa0.0.0.3.0       EWA0         00-00-F8-1F-70-3D
    
    For additional information, see the HP OpenVMS Operating System for Alpha and VAX Software Product Description and the hardware manuals that you received with your Alpha computer.
  2. At the console prompt, enter the following command, where lan-device-name is the local area network (LAN) device (for example, EWA0) identified with your computer:
    >>> B -FLAGS 0,0 -FILE APB_2073 lan-device-name 
    For information about the LAN devices your system supports, see the following table. For additional information, see the hardware manuals that you received with your Alpha computer and the OpenVMS software product description (SPD). The APB file name in the previous command is the unique file name that was assigned to the APB.EXE file when it was copied from the operating system CD-ROM to the InfoServer. This file is the name of the APB program used for the initial system load (ISL) boot program.

    NoteIf you are using a DEC 3000 or 4000 series system, note the following:
    • On DEC 3000 series systems, you can boot through the InfoServer with an Ethernet PMAD device or FDDI DEFTA device by specifying the device name as "n/ESA0". The value for n is the TURBOchannel slot number, which you can obtain by entering the SHOW CONFIGURATION command at the console prompt (>>>) and examining the display. For more information, see Booting with a PMAZB or PMAZC TURBOchannel Adapter.


    • On DEC 4000 series, you must specify the ISL file name in uppercase (for example, APB_2073).

  3. The InfoServer ISL program then displays the following menu:
       
    Network Initial System Load Function

        4     -        Select Options
        5     -        Stop
     
    Enter a function ID value:
  4. Respond to the prompts as follows, pressing the Return key after each entry:

    1. Enter 3 for the function ID.
    2. Enter 2 for the option ID.
    3. Enter the service name (ALPHA0732).
    A sample display follows:
    Enter a function ID value: 3 
     OPTION          OPTION
       ID
       1     -       Find Services
       2     -       Enter known Service Name
     
    Enter an Option ID value: 2 
    Enter a Known Service Name: ALPHA0732 

After you boot, the system displays a menu from which you can choose options to perform the following tasks:

Booting Manually from the System Disk  

Boot the system disk manually as follows:

IF ... THEN GO TO...
the OpenVMS Alpha operating system is running,
step 1.
the OpenVMS Alpha operating system is not running,
step 4.

  1. Log in to the SYSTEM account.
  2. Enter the following command and press the Return key:
    $ @SYS$SYSTEM:SHUTDOWN
  3. Answer the questions displayed by the system. When the procedure asks if an automatic reboot should be performed, press the Return key for NO. When the procedure is finished, it displays the following message:
    SYSTEM SHUTDOWN COMPLETE
  4. Halt the system by entering Ctrl/P or by pressing the Halt button. (See Halting the System for more information about how to halt your Alpha computer.)
  5. Enter the BOOT command in the following format:

    BOOT device-name

    Substitute the device name of the system disk for device-name. For example, to boot from a drive with a device name of DKA400, enter the following command and press the Return key:
    >>> BOOT DKA400
    To boot from the network, enter the following command and press the Return key:
    >>> BOOT ESA0

Performing a Conversational Boot  

A conversational boot is most commonly used in research and development environments and during software upgrades. Perform a conversational boot to stop the boot process before it completes. The boot process stops after it loads SYS$SYSTEM:SYSBOOT.EXE and displays the SYSBOOT> prompt. At the SYSBOOT> prompt, you can enter specific OpenVMS System Generation utility (SYSGEN) commands to do the following:

There are several ways to perform a conversational boot. The following procedure is the most direct:

IF ... THEN GO TO...
the OpenVMS Alpha operating system is running,
step 1.
the OpenVMS Alpha operating system is not running,
step 4.

  1. Log in to the SYSTEM account.
  2. Enter the following command and press the Return key:
    $ @SYS$SYSTEM:SHUTDOWN
  3. Answer the questions displayed by the system. When the procedure asks if an automatic reboot should be performed, press the Return key for NO. When the procedure is finished, it displays the following message:
    SYSTEM SHUTDOWN COMPLETE
  4. Halt the system by entering Ctrl/P or by pressing the Halt button. ( Halting the System for more information about how to halt your Alpha computer.)
  5. To begin the conversational boot, enter the BOOT command in the following format:

    BOOT -FLAGS 0,1 [device-name]

    for device-name, substitute the device name of the drive from which you want to boot. For example, if the system disk has a device name of DKA400, enter the following command and press the Return key:
    >>> BOOT -FLAGS 0,1 DKA400
    If you do not specify a device name, the system boots from the boot device assigned when you entered the SET BOOTDEF_DEV command.
  6. At the SYSBOOT> prompt, you can enter any of the SYSGEN commands listed in SYSGEN Commands Used in the SYSBOOT Procedure. For more information about these SYSGEN commands, see the HP OpenVMS System Management Utilities Reference Manual: M--Z.
  7. When you finish using the SYSGEN commands, enter the CONTINUE command to complete the boot process.

    Table 1   SYSGEN Commands Used in the SYSBOOT Procedure
    Command Description
    CONTINUE
    Resumes the boot procedure.
    DISABLE CHECKS
    Inhibits checking of parameter values specified with the SET command.
    ENABLE CHECKS
    Permits checking of parameter values specified with the SET command.
    HELP
    Displays a summary of the SYSBOOT commands on the terminal screen.
    SET parameter-name
    Establishes the value of a system parameter.
    SET/STARTUP
    Sets the name of the system startup command procedure.
    SHOW [parameter]
    Displays active, current, default, maximum, and minimum values for specific parameters. (Use qualifiers to display characteristics of parameters grouped by categories.)
    USE [file-spec]
    Specifies a parameter file to be used as a source of values. You must enter the entire file specification, including device and directory; you cannot specify a logical name.

For examples of using conversational booting, see Booting with Minimum Startup and Booting in an Emergency.

Booting with Minimum Startup  

In certain cases, you might want to boot your system without performing the full sequence of startup events. For example, if a startup event prevents you from logging in, you might want to boot the system without executing the startup so that you can log in and fix the problem. You can use the conversational boot to specify a minimum startup.


NoteBecause this procedure bypasses specific startup operations, it does not autoconfigure the system's peripheral devices.

Boot the system with minimum startup as follows:
  1. Begin the conversational boot by entering the BOOT command in the following format:

    BOOT -FLAGS 0,1 [device-name]

    For device-name, substitute the device name of the drive from which you want to boot. For example, if the system disk has a device name of DKA400, enter the following command and press the Return key:
    >>> BOOT -FLAGS 0,1 DKA400
  2. Enter the following command and press the Return key:
    SYSBOOT> SET STARTUP_P1 "MIN"
  3. Enter the following command to continue booting:
    SYSBOOT> CONTINUE
  4. After the system boots, log in and enter the following commands to invoke SYSMAN and clear the STARTUP_P1 parameter you set in step 2:
    $ RUN SYS$SYSTEM:SYSMAN
    SYSMAN> PARAMETERS USE CURRENT
    SYSMAN> PARAMETERS SET STARTUP_P1 ""
    SYSMAN> PARAMETERS WRITE CURRENT

Booting with the XDelta Utility (XDELTA)  

The XDelta utility (XDELTA) is a debugging tool that system programmers use. The procedure for booting all Alpha computers with XDELTA is the same.

The following table describes the valid values you can specify when booting with XDELTA:

Value System Response
0
Normal, nonstop boot (default).
1
Begins a conversational boot and then displays the SYSBOOT prompt.
2
Includes XDELTA but does not take the initial breakpoint.
3
Displays the SYSBOOT prompt and includes XDELTA but does not take the initial breakpoint.
6
Includes XDELTA and takes the initial breakpoint.
7
Includes XDELTA, displays the SYSBOOT prompt, and takes the initial breakpoint at system initialization.

The following is an example of booting with XDELTA from the console prompt:

>>> BOOT -FLAGS 0,7
For more information about using XDELTA, see the OpenVMS Delta/XDelta Debugger Manual.

Booting from a Different Directory  

By default, the OpenVMS Alpha operating system is installed in the system root directory [SYS0]. However, if you have created a cluster system disk, you can use the SYS$MANAGER:CLUSTER_CONFIG.COM procedure to add a copy of the operating system to a different root directory. (See the HP OpenVMS System Manager's Manual for more information about using the SYS$MANAGER:CLUSTER_CONFIG.COM procedure.)

To boot from a different directory (for example, [SYS3]), enter the BOOT command as follows:

>>> BOOT -FLAGS 3,0  DKA200

Booting with a PMAZB or PMAZC TURBOchannel Adapter  

PMAZB and PMAZC TURBOchannel adapters are adapters that are software-compatible with the integrated SCSI ports on DEC 3000 Alpha series systems.

The DEC 3000 Alpha series system consoles implement the SHOW CONFIGURATION console command, which displays information about the TURBOchannel options and the built-in adapters in the system. When a PMAZB or PMAZC adapter is installed in the TURBOchannel, the SHOW CONFIGURATION command displays the "PMAZB-AA" or "PMAZC-AA" string, the TURBOchannel slot number, and the device status.

The DEC 3000 Alpha series consoles also implement the SHOW DEVICE command, which displays information about the devices in the system. Because the integrated SCSI adapter is built into every DEC 3000 Alpha series system, the SHOW DEVICE console command can display the SCSI devices connected to the integrated SCSI ports. However, the SHOW DEVICE console command cannot display the SCSI devices connected to the PMAZB or PMAZC SCSI ports.

To make the console display the devices connected to the PMAZB or PMAZC SCSI ports, enter the following command at the console prompt, wherex is the TURBOchannel slot number in which the PMAZB or PMAZC adapter is installed:

>>> TEST TCx CNFG 
This command displays the devices that are connected to each SCSI port of the PMAZB or PMAZC adapter. The device controller letters are either A or B, based upon the PMAZB or PMAZC ports to which the devices are connected. Do not confuse these devices with any DKAxxx or DKBxxx devices displayed by the SHOW DEVICE command, which shows SCSI devices on the integrated SCSI ports only.

To boot from a device connected to a PMAZB or PMAZC adapter, enter the boot command as follows:

>>> BOOT "x/dkyzzz"
The following conventions are used:

The OpenVMS Alpha operating system does not distinguish between the PMAZB or PMAZC adapter and the integrated SCSI adapter. The operating system views them as identical adapters. Because the operating system searches for I/O adapters in backplane slot number order, device controller letters are assigned that correspond to the backplane order of the TURBOchannel options, followed by the integrated adapters. This is different from console SCSI device naming, which always designates SCSI devices on the integrated SCSI ports as either "A" or "B" port devices.

Example

On a DEC 3000 Model 500 Alpha system with no TURBOchannel options installed, the OpenVMS Alpha operating system names the integrated SCSI ports PKA0 and PKB0, and the devices connected to the ports inherit the controller letter from the port controller letter (A or B). However, if a PMAZB or PMAZC adapter is installed in the TURBOchannel, the operating system names the PMAZB or PMAZC SCSI ports PKA0 and PKB0 and names the integrated SCSI ports PKC0 and PKD0. The devices connected to the ports inherit the controller letter from the port controller letter (A, B, C, or D).

Booting over the Network with an Alternate TURBOchannel Adapter  

You can use an alternate TURBOchannel adapter to boot a DEC 3000 series Alpha computer (with the TURBOchannel option) over the network in an InfoServer or OpenVMS Cluster environment. Examples of alternate TURBOchannel adapters are the PMAD (which connects to the Ethernet) and the DEFTA (which connects to the FDDI).

To boot from a TURBOchannel device connected to one of these alternate adapters, enter the boot command as follows:

>>> BOOT "n/ESA0"
The value for n is the TURBOchannel slot number for the device, which you can obtain by entering the SHOW CONFIGURATION command at the console prompt (>>>) and examining the display. In the following example, the TURBOchannel slot number (listed under the "TCINFO" column) is 0:

Booting in an Emergency  

If a system problem prevents your system from booting, you might need to perform an emergency boot operation. Emergency Boot Procedures summarizes these emergency boot operations, and the sections that follow describe each boot operation in more detail.

Table 2   Emergency Boot Procedures
Operation When to Use
Booting with default system parameters
When parameter values in the parameter file have been modified so that the system is unbootable
Booting without startup and login procedures
If an error in the startup or login procedures prevents you from logging in
Booting without the user authorization file
If you have forgotten the password and cannot log in to a privileged account

Booting with Default System Parameters  

If the current values stored in the parameter file have been incorrectly modified, these incorrect values might cause the system to become unbootable. With a conversational boot operation, you can reset the active values for all system parameters to the default value. (In most cases, HP recommends that you use AUTOGEN to modify system parameters. In certain cases, however, you can use a conversational boot to modify a parameter value temporarily. To change a parameter value permanently, you must edit MODPARAMS.DAT and run AUTOGEN. For instructions, see the chapter entitled "Modifying System Parameters" in the HP OpenVMS System Manager's Manual, Volume 2: Tuning, Monitoring, and Complex Systems.) The default values allow you to boot the system temporarily so you can correct the problem.

How to Perform This Task

  1. Begin the conversational boot by entering the BOOT command in the following format:

    BOOT -FLAGS 0,1 [device-name]

    For device-name, substitute the device name of the drive from which you want to boot. For example, if the system disk has a device name of DKA400, enter the following command and press the Return key:
    >>> BOOT -FLAGS 0,1 DKA400
  2. At the SYSBOOT> prompt, enter the following command:
    SYSBOOT> USE DEFAULT
    This command specifies that default values should be used for all parameters.
  3. Enter the following command to continue booting:
    SYSBOOT> CONTINUE
  4. When the system finishes booting, determine which changed parameter caused the problem and reset the parameter value. If you specified the value for the parameter in the AUTOGEN parameter file MODPARAMS.DAT, fix the value in that file and run AUTOGEN. For more information, see the chapter entitled "Modifying System Parameters" in the HP OpenVMS System Manager's Manual, Volume 2: Tuning, Monitoring, and Complex Systems.
  5. Shut down and reboot the system.

Example

SYSBOOT> USE DEFAULT                        
SYSBOOT> CONTINUE 
Username: SYSTEM
Password: 
$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> PARAMETERS USE CURRENT
SYSMAN> PARAMETERS SET NPAGEDYN 2999808
SYSMAN> PARAMETERS WRITE CURRENT
SYSMAN> EXIT           
$ EDIT SYS$SYSTEM:MODPARAMS.DAT
.
.
.
[Insert the following line in MODPARAMS.DAT:]
MIN_NPAGEDYN = 2999808 
.
.
.
$ @SYS$UPDATE:AUTOGEN SAVPARAMS REBOOT

Booting Without Startup and Login Procedures  

If the system does not complete the startup procedures or does not allow you to log in, you might need to bypass the startup and login procedures. The startup and login procedures provided by HP should always work. However, if you introduce an error when modifying the startup or login procedures, it is possible to accidentally lock yourself out of the system.

How to Perform This Task

  1. Begin the conversational boot by entering the BOOT command in the following format:

    BOOT -FLAGS 0,1 [device-name]

    For device-name, substitute the device name of the drive from which you want to boot. For example, if the system disk has a device name of DKA400, enter the following command and press the Return key:
    >>> BOOT -FLAGS 0,1 DKA400
  2. Enter the following command at the SYSBOOT> prompt:
    SYSBOOT> SET/STARTUP OPA0:
  3. Enter the following command to continue booting:
    SYSBOOT> CONTINUE
  4. When the system is booted, the operator console displays the DCL command prompt ($). You are logged in.
  5. Enter the following DCL command:
    $ SET NOON
    This command directs the operating system to ignore any errors that might occur. If you do not enter this command and you invoke an error, the system will log you out.
  6. Correct the error condition that caused the login failure. (That is, make the necessary repairs to the startup or login procedures, or to the SYSUAF.DAT file.)

    Invoke a text editor to correct the startup or login file. Note that some system consoles might not supply a screen-mode editor. You can also copy a corrected file and delete the incorrect version by using the RENAME and DELETE commands.
  7. Invoke SYSMAN and enter the following commands to reset the startup procedure:
    $ RUN SYS$SYSTEM:SYSMAN
    SYSMAN> PARAMETERS USE CURRENT
    SYSMAN> PARAMETERS SET/STARTUP SYS$SYSTEM:STARTUP.COM
    SYSMAN> PARAMETERS WRITE CURRENT
    SYSMAN> EXIT
    $ 
  8. Perform a normal startup by entering the following command:
    $ @SYS$SYSTEM:STARTUP

Example

SYSBOOT> SET/STARTUP OPA0:
SYSBOOT> CONTINUE
$ SET NOON
$ SET DEFAULT SYS$SYSROOT:[SYSEXE]
$ RUN SYS$SYSTEM:SYSMAN
SYSMAN> PARAMETERS USE CURRENT
SYSMAN> PARAMETERS SET/STARTUP SYS$SYSTEM:STARTUP.COM
SYSMAN> PARAMETERS WRITE CURRENT
SYSMAN> EXIT
$ @SYS$SYSTEM:STARTUP

Booting Without the User Authorization File  

Ordinarily, the startup and login procedures provided by HP always work; however, certain user interventions can cause them to fail. A very simple way to lock yourself out of the system is to set passwords to login accounts and forget them. In such an emergency, you can use the alternate user authorization file rather than the standard user authorization file.


NoteYou can use this method only to log in to the system from the console terminal; you cannot use other terminal lines.

Setting the system parameter UAFALTERNATE defines the logical name SYSUAF to refer to the file SYS$SYSTEM:SYSUAFALT.DAT. If this file is found during a normal login, the system uses it to validate the account and prompts you for the user name and password.

If it cannot find this file, the system assumes that the UAF is corrupt and accepts any user name and any two passwords to log you in to the system from the system console. Logins are prohibited from all other terminal lines.

When you perform this procedure, the system assigns the following values to your user account:

Field Value
Name
User name
UIC
[001,004]
Command interpreter
DCL
Login flags
None
Priority
Value of the system parameter, DEFPRI
Resources
Values of the PQL system parameters
Privileges
All

The process name is usually the name of the device on which you logged in (for example, _OPA0:).

How to Perform This Task

  1. Begin the conversational boot by entering the BOOT command in the following format:

    BOOT -FLAGS 0,1 [device-name]

    For device-name, substitute the device name of the drive from which you want to boot. For example, if the system disk has a device name of DKA400, enter the following command and press the Return key:
    >>> BOOT -FLAGS 0,1 DKA400
  2. At the SYSBOOT> prompt, enter the following command:
    SYSBOOT> SET UAFALTERNATE 1                  
  3. If your system is running DECwindows software, you must also disable the windowing system by entering the following command:
    SYSBOOT> SET WINDOW_SYSTEM 0
  4. Enter the CONTINUE command to continue booting:
    SYSBOOT> CONTINUE
  5. When the startup procedure completes, log in on the console terminal by entering any user name and any two passwords in response to the Username: and Password: prompts.
  6. Enter the following command to use the default UAF:
    $ DEFINE/SYSTEM/EXECUTIVE_MODE SYSUAF SYS$SYSTEM:SYSUAF.DAT
  7. Use the Authorize utility to fix the problem that caused you to be locked out of the system (for example, a forgotten password). Enter HELP MODIFY at the UAF> prompt for information about modifying passwords. For more details, see the HP OpenVMS System Management Utilities Reference Manual: A--L.
  8. Enter the following commands to invoke SYSMAN and clear the UAFALTERNATE system parameter you set in step 2:
    $ RUN SYS$SYSTEM:SYSMAN
    SYSMAN> PARAMETERS USE CURRENT
    SYSMAN> PARAMETERS SET UAFALTERNATE 0
    In most cases, HP recommends that you use AUTOGEN to modify system parameters. However, because this parameter is only being changed temporarily, you can use SYSMAN to change it back.
  9. If you disabled the windowing system in step 3, reenable it by entering the following command:
    SYSMAN> PARAMETERS SET WINDOW_SYSTEM 1
  10. Enter the following command to save the changed system parameter values:
    SYSMAN> PARAMETERS WRITE CURRENT
  11. Shut down and reboot the system.

Example

SYSBOOT> SET UAFALTERNATE 1
SYSBOOT> SET WINDOW_SYSTEM 0
SYSBOOT> CONTINUE
