5.12 Disk Drive/Drive Tray Replacement
A coprocessor software recovery activity must be performed at this point.
The work to be done differs depending on which hard drive was replaced.
If the primary drive is replaced with a spare from Honeywell logistics
(formatted but no data files), the operating software is no longer available
for boot purposes. This requires special procedures to boot from a local
DAT drive or from a DAT drive accessed over the PIN network. A
successful boot must be followed by a complete software restore from a
previously customer created “Backup tape”. These procedures are found in
the A
X
M System Administration manual.
If the primary drive is replaced with a primary drive from another A

S, The coprocessor will boot and assume the environment that existed in
the original system. A complete software restore operation and reboot will
be required to recover.
If the secondary drive is replaced, the coprocessor will boot successfully
from the primary drive. The Honeywell provided spare drive is already
properly formatted for use. If the replacement drive was obtained from
another system (used drive), use the “mediainit” command to destroy any
previous file structure that may exist on the drive prior to mounting the
drive. After mounting the drive using the “mount” command, a complete
software restore from a previously created “Backup tape” and reboot is
required to recover.

Be sure none of the cables are pinched between
the cover and the tray at any point. Failing to do
so can cause damage to the cable.
