MAP 2410: SSA Repair Verification
This MAP helps you to verify that FRUs that you have exchanged for new FRUs, or
repair actions that you have done, have solved all the problems on the subsystem.
Attention:
do not switch off the using system when servicing an SSA link or an enclosure in which
SSA devices are installed. Enclosure power cables and external SSA cables that
connect devices to the using system can be disconnected while that system is running.
1. (from steps 3 and 5 in MAP 2320: SSA Link; step 3 in MAP 2323: SSA Intermittent
Link Error; step 5 in MAP 2324: SSA RAID)
Have you exchanged a FRU?
NO
YES
2.
(from step 1)
Before you arrived at this MAP, you exchanged one or more FRUs for new FRUs.
Some of those FRUs have Power lights (for example, disk drives and
fan-and-power-supply assemblies).
If none of the FRUs that you exchanged has a Power light, go to step 3. If some, or
all, of the FRUs that you exchanged have Power lights, check whether all those
Power lights are on.
Do the FRUs that you have exchanged have their Power lights on?
NO
YES
3. (from step 2)
Are all Check lights off?
Note: For FRUs that do not have a Check light, answer YES.
NO
YES
Unless the using system needs to be switched off for some other reason,
a. Run diagnostics, in System Verification mode, to the device that
reported the problem.
Note: Do not run Advanced Diagnostics; otherwise, errors might be
logged on other using systems that share the same loop.
b. Go to step 4 on page 476.
Go to step 2.
a. Exchange, for a new one, the FRU whose Power light is off.
b. Go to step 3.
Go to step 3.
Go to the START MAP for the enclosure in which the device that has its
Check light on is installed.
a. Run diagnostics, in System Verification mode, to the device that
reported the problem.
