Considerations
for ordering
replacement
drives
The only thing to consider when ordering a replacement disk drive is drive
capacity.
The spare drive is supplied properly formatted, but without HP-UX
software.
If the primary drive is the one being replaced, the appropriate recovery
procedure must be used to boot from “HP-UX Install” DAT tape on an
alternate boot source such as a DAT drive connected locally or remote DAT
drive accessible over the network. Upon successful boot, a complete
software restore must be performed from a previously customer generated
DAT drive “Backup Tape” (or other available source). This will restore the
coprocessor file system to reflect conditions that existed when the “Backup
Tape” was generated.
If the second (optional drive) is being replaced, the coprocessor will boot
successfully from the primary drive. The new replaced second drive can be
put under system control using the “mount” command without any
preparation steps. A software restore must be performed from a previously
customer generated DAT drive “Backup Tape” (or other available source).
This will restore the coprocessor file system to reflect conditions that
existed when the “Backup Tape” was generated.
The parts list in the last section of this manual provides the drive part
numbers.
Procedures for booting from a DAT drive to recover from a failed primary
hard drive are provided in the

Procedures for creating “Backup tapes” and software restore operations are

Appropriate care must be exercised when a replacement disk drive does not
come directly from Honeywell spare parts (from hot spares or training
system).
If the primary drive is replaced with a drive containing files from another
system, it may have to have the proper files resident to allow a software
boot operation; (i.e., it was the primary drive in the previous system). The
coprocessor will boot from this replacement device and assume the exact
configuration that existed on the previous system. After making the
appropriate configuration changes to access the PIN network, a complete
software restore from customer generated DAT drive “Backup Tape” (or
other available source) is required to get the coprocessor file structure to
reflect conditions existing prior to drive replacement.
If the primary drive is replaced by a drive that was the second drive on
another system, the appropriate recovery procedure must be used to boot
operating software from an alternate boot source such as a DAT drive. This
DAT drive may be locally connected or accessible over the network. A
complete software restore is required to get the coprocessor file structure to
reflect conditions existing prior to drive replacement.
