Booting the OpenVMS
Alpha Operating System CD
If you need to boot the OpenVMS Alpha operating system CD,
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:
BOOT -FLAGS 0,0 source-drive
>>>
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 using the InfoServer, do the
following:
For additional information, refer to the HP OpenVMS for Integrity Servers and HP OpenVMS Alpha Version 8.2 Operating Systems Software Product Description (SPD 82.35.xx) and the hardware manuals that you received with your Alpha computer.>>>

For information about the LAN devices your system supports, see Supported LAN Devices. Ethernet device EWA0 refers to the first EW device. Subsequent devices are named EWB0, EWC0, and so on. For most systems, you can use the SHOW CONFIGURATION console command to list LAN devices available for boot. For additional information, refer to 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 to the InfoServer. This file is the name of the APB program used for the initial system load (ISL) boot program.>>>

After you boot, the system displays a menu from which you can choose options to perform the following tasks:
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. If your system is not a DEC 3000 Alpha series system,
skip to the next section.
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:
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 DKA>>>
TEST TC

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:
The following conventions are used:>>>
BOOT "
x/dkyzzz
"
x
is the TURBOchannel slot number in which the PMAZB
or PMAZC adapter is installed.dk
is the device code of the boot device.y
is either A or B, depending on the SCSI port of the
PMAZB or PMAZC adapter that contains the boot device.zzz
is the SCSI unit number of the boot device.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.
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).

Performing a Conversational
(Interactive) 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:

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

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 |
---|---|

The following is an example of booting with XDELTA from the console prompt:
For more information about using XDELTA, refer to the HP OpenVMS Delta/XDelta Debugger Manual.>>>
BOOT -FLAGS 0,7
Booting from a Different
Root 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$MANAGER:CLUSTER_CONFIG.COM procedure
to add a copy of the operating system to a different root directory.
(Refer to the HP OpenVMS System Manager's Manual for more information about using the SYS$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 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:
The value for>>>
BOOT "
n
/ESA0"
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

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.
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, refer
to 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.

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 procedure, it is possible to accidentally
lock yourself out of the system.

Booting Without the
User Authorization File
Ordinarily, the startup and login procedures provided by HP
always work; however, certain conditions can cause them to fail.
A simple way to lock yourself out of the system is to set passwords
to login accounts and forget them. Another way to be locked out
is if one or more core system Product Authorization Key (PAK) software
licenses are unavailable or expired. In such emergencies, perform
a conversational emergency boot by following the steps given in
this section.
BOOT -FLAGS 0,1 [device-name
]
If your system has a hardware password (various systems support a password that prevents unauthorized access to the console), you need this password for logging in to the console. If you do not have this password, contact HP customer support to reset the hardware console password.>>>

SYSBOOT>
SET WRITESYSPARAMS 0

CONTINUE
$
SPAWN
$
@SYS$SYSTEM:STARTUP
Instead of using the SET/STARTUP OPA0: command, an alternative method
of booting under these emergency conditions is to set the UAFALTERNATE
system parameter to use the alternate authorization file rather
than the standard user authorization file. Setting the system parameter
UAFALTERNATE defines the logical name SYSUAF to refer to the file SYS$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. HP does not recommend this method. If an alternate SYSUAFALT.DAT file has been configured on your system, the UAFALTERNATE method will likely fail (assuming you do not know the password for the privileged account stored within the SYSUAFALT.DAT file). In addition, the OPA0: system console is critical to system operations and system security and allows access when the SYSUAF system authorization database is unavailable or corrupted; when core product license PAKs are not registered, are expired, or are disabled; and in various system failures. |
