3. In a system with duplex SPEs, the tests run on the standby Disk circuit
pack are identical to those run on the active Disk circuit pack. The DUPINT
circuit pack handles communications between the active and standby
SPEs for the control channel and memory shadowing. Therefore, problems
with the DUPINT circuit pack may affect maintenance testing of the
standby Disk circuit pack.
4. The
disk data will likely be destroyed
if:
a. Power is removed from the Disk circuit pack while its yellow LED is
on.
b. The Disk circuit pack is removed while its yellow LED is on.
5.
Tape data may be destroyed
if the Disk circuit pack is removed while the
yellow LED on the Tape Drive is on.
Replacing the Disk Circuit Pack
■ If the SPE is not duplicated:
1. Issue the
busyout host-adapter
command.
The Host Adapter should be "busied out" to prevent other
applications from trying to access the disk or tape.
2. Replace the Disk circuit pack.
3. Issue the
reset host-adapter
command.
This allows the disk to "spin up."
4. Issue the
release host-adapter
command.
5. Issue the
status spe
command and verify that the disk is now in
service.
6. Issue the
restore disk
command to copy the boot image files,
translation files, announcement files, and program update files from
the tape to the disk. This may take up to an hour to complete.
7. Issue the
test stored-data
command to verify that the files on all
storage devices are consistent.
■ If the SPE is duplicated:
1. To replace the Disk circuit pack on a system equipped with
duplicated SPEs, use the lock-and power-down procedure
described in
Replacing SPE Circuit Packs
in Chapter 5.
2. After the standby SPE is powered up and fully refreshed, enter the
restore disk command to copy the bootimage files, translation
files, announcement files, and program update files from the tape to
the disk.
3. Test the standby Disk using the test disk long command.
