SSA Maintenance Analysis Procedures (MAPs)
The maintenance analysis procedures (MAPs) describe how to analyze a failure that
has occurred in an SSA loop.
How to Use the MAPs
Attention: Unless the using system needs to be switched off for some other reason,
do not switch off the using system when servicing an SSA loop. Enclosure power
cables and external SSA cables that connect the devices to the using system can be
disconnected while that system is running.
v
To isolate the FRUs, do the actions and answer the questions given in the MAPs.
v
When instructed to exchange two or more FRUs in sequence:
1. Exchange the first FRU in the list for a new one.
2. Verify that the problem is solved. For some problems, verification means running
the diagnostic programs (see the using-system service procedures).
3. If the problem remains:
a. Reinstall the original FRU.
b. Exchange the next FRU in the list for a new one.
4. Repeat steps 2 and 3 until either the problem is solved, or all the related FRUs
have been exchanged.
5. Do the next action indicated by the MAP.
Attention: Disk drives are fragile. Handle them with care, and keep them well away
from strong magnetic fields.
