NOTE: If you boot the OpenVMS Alpha operating system CD from an InfoServer but lose
your connection during the installation or upgrade procedure (the system is unresponsive and
pressing Ctrl/Y does not return you to the menu), do the following:
THEN ...IF ...
You previously chose the
INITIALIZE option
1. Reboot the OpenVMS Alpha operating system CD.
2. Choose the install/upgrade option (1) on the menu and perform the installation or
upgrade procedure again.
You previously chose the
PRESERVE option
1. Reboot the OpenVMS Alpha operating system CD.
2. Enter the DCL environment by choosing option 8 on the menu.
3. Mount the device containing your backup copy of the target disk and the device that
is your target disk.
4. Restore the backup copy of your target disk by entering the appropriate BACKUP
commands. (See Appendix F (page 301) for complete information about using MOUNT
and BACKUP commands to restore a system disk.)
5. Log out from the DCL environment.
6. Choose the install/upgrade option (1) on the menu and perform the installation or
upgrade procedure again.
A.1.2 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:
>>> 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:
• x is the TURBOchannel slot number in which the PMAZB or PMAZC adapter is installed.
• dk is the device code of the boot device.
