7.1.1 Load the 3B21 Emulator and Operating System CD-ROM and Boot the AW
OVERVIEW
This part of the procedure provides a description for recovering the Administrative
Workstation (AW) operating system and the 3B21 emulator. It uses the 3B21
Emulator and Operating System CD-ROM to restore the AW system boot disk, either
from the CD-ROM or from a backup tape.
PROCEDURE
1. Stop the AW. See “Halt the Administrative Workstation,” Procedure 4.2.
2. Load the 3B21 Emulator and Operating System CD-ROM into the DVD/CD-ROM
drive.
Caution: Booting from this CD-ROM and loading from the CD-ROM or a
backup tape will format the AW disks and overwrite the operating system
and emulator with data from the CD-ROM or tape. After this procedure is
executed, load the remaining generic backup tapes.
3. Enter the following command at the ok prompt to boot the AW from the
CD-ROM:
boot cdrom
If “cdrom” is not defined correctly, use the following commands to verify the
DVD/CD-ROM drive device ID and set the CD-ROM device alias:
For Netra

t 1120
probe-scsi
devalias
nvalias cdrom /pci@1f,4000/scsi@3/disk@5,0:f
For Netra 20

nvalias cdrom /pci@8,700000/scsi@6/disk@6,0:f
For Netra 240
devalias
nvalias cdrom /pci@1e,600000/ide@d/cdrom@0,0:f
When the AW starts to boot from the CD-ROM, messages similar to those shown
in the following examples are output on the system console:
