MAP 2010: START
This MAP is the entry point to the MAPs for the adapter. If you are not familiar with
these MAPs, read “How to Use the MAPs” on page 443 first.
You might have been sent here because:
v The system problem determination procedures sent you here.
v A problem occurred during the installation of a disk subsystem or a disk drive.
v Another MAP sent you here.
v A customer observed a problem that was not detected by the system problem
determination procedures.
Attention: Unless the using system needs to be switched off for some other reason,
do not switch off the using system when servicing the 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.
1.
Do you have an SSA subsystem (5-character) SRN?
NO Go to step 2.
YES Go to “Service Request Numbers (SRNs)” on page 411.
2. (from step 1)
v If the system diagnostics are available, go to step 3.
v If the system diagnostics are not available, but the stand-alone diagnostics are
available:
a. Load the stand-alone diagnostics.
b. Go to step 3.
v If neither the system diagnostics nor the stand-alone diagnostics are available, go
to the problem determination procedures for the enclosure that contains the disk
drives.
3. (from step 2)
Run the diagnostics in Problem Determination mode.
Did the diagnostics produce an SRN?
NO Go to step 5 in “MAP 2410: SSA Repair Verification” on page 475.
YES Go to step “Service Request Numbers (SRNs)” on page 411.
