3. In a system with duplex SPEs, the tests run on the standby Dis k circuit
pack are identical to thos e run on the active Disk circuit pa ck. The DUPINT
circuit pack hand les communications b etween the active and stand by
SPEs for the control channel and memory shadowing . Therefore, problems
with the DUPINT circuit pack may affect maintena nce 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 pac k is removed while its yellow LED is on.
5.

Tape data may be destroyed

if the Disk circuit pac k is removed while the
yellow LED on the Tape Drive is on.
Replacing the Disk Circuit Pack
■If the SPE is not dup lic ated :
1. Issue the busyout host-adapter command.
The Host Adapter should be "busied out" to prevent other
applications from trying to access the d isk or tape.
2. Replace the Disk circuit p ack.
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 c opy the boot image files,
translation files, announcement files, and p rogram 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 c onsistent.
■If the SPE is du plic ate d:
1. To replace the Disk circuit pack on a system e quipped with
duplicated SPEs, use the lock-and power-down proc edure
described in

Repla cing SPE Cir cuit Packs

in Chapter 5.
2. After the standby SPE is powered up and fully refreshed, enter the
restore disk command to copy the b ootimage files, translation
files, announcement files, and p rogram update files from the ta pe to
the disk.
3. Test the standby Disk using the test disk long command .
