SSA - Repair Verification
This procedure helps you to verify a repair after a FRU has been exchanged for a
new one.
Attention: Unless the system unit needs to be turned off for some other reason,
do not turn off the system when servicing an SSA link or
a
unit in which SSA
devices are installed. Unit power cables and external SSA cables that connect
devices to the system can be disconnected while that system is running.

Before you arrived at this procedure, you might
have exchanged one or more FRUs for new FRUs.
Some of those FRUs (for example, disk drives)
have Power lights.
Check whether all those Power lights are on.
Do all the FRUs you exchanged have their power
lights on (where applicable)?
YES
NO
2
l
Exchange, for a new one, the FRU whose
Power light is off. Then, go to step 2.
Are all check lights off?
YES
NO
3
l
Go to START for the device with its Check
light on.
Run concurrent diagnostics to the device that
reported the problem.
• If the original problem was not reported by a
device, run diagnostics to each SSA RAID
Adapter in the system unit.
• Run the Fix procedure (see "The Event/Error
Logger Utility" on page 126).
If you have a RAID array, and the problem
remains, go to RAID Checkout at step 37 of "SSA
- RAID ERRORS" on page 90.
End of procedure
Note: If you do not run this service aid, the
diagnostics might create an SRN for a
problem that has already been solved.
Do not run nonconcurrent diagnostics;
otherwise, errors are logged on other
systems that share the same loop.
If you have just exchanged a disk drive or
an SSA RAID Adapter, you must use the
configurator to restore the device to the
system.
