MAP 2323: SSA Intermittent Link Error
This MAP helps you to isolate FRUs that are causing an intermittent SSA link problem.
You are here because you have an SRN from the series 21000 through 29000.
If you are not familiar with SSA loops, read the information relating to SSA links,
strings, and loops contained in the
IBM SerialRAID Adapter: Installation and User's
Guide
.
Attention: It is not necessary to turn the system off when servicing an SSA loop,
unless the system unit needs to be turned off for some other reason. Power cables and
external SSA cables can be disconnected while the system is running.
