Specifications

If the SRN is 33xxx, the second device of the two is located at PAA +1.
Note: If the SSA address (
AA ) in the SRN is higher than the highest SSA address
that is displayed for the adapter port (
P ), that address is the address of the
SSA adapter.
3. Go to “Step 2323-3”.
Step 2323-3
If a pdisk has a status other than good, use the identify function to find the pdisks on
each side of that drive, and replace the defective drive. Then go to ″MAP 410: Repair
Checkout″ in
Diagnostic Information for Multiple Bus Systems to verify the repair.
If not, continue.
The problem is in the SSA link between the two devices identified in “Step 2323-2” on
page 75.
Exchange, in the sequence shown, the following FRUs for new FRUs. Ensure that for
each FRU exchange, you go to ″MAP 410: Repair Checkout″ in Diagnostic Information
for Multiple Bus Systems
to verify the repair.
1. One of the two devices that are identified by the SRN (see “Removing Hot-Plug
SSA Disk Drives” on page 314)
2. The other of the two devices
3. The internal SSA connections
4. The external SSA cable
MAP 2324: SSA hot-swap disk drive RAID
This map helps you solve problems that have occurred in SSA RAID arrays.
You have been sent to this MAP because you have one of the following SRNs: 46000,
47000, 47500, 49000, 49100, 49500.
Attention: Unless the using system needs to be switched off for some other reason,
do not turn off the power when servicing an SSA link .
Before starting this MAP, ensure that all the disk drives are working correctly:
1. Run diagnostics in Problem Determination mode to identify any disk drive problems
that have occurred.
2. Run the Link Verification service aid to find all power problems, SSA link problems,
and SSA disk drives that have a Failed status.
3. Correct all those problem before you continue.
If you still have a problem, go to MAP 2324 in
Advanced SerialRAID Adapters User’s
Guide and Maintenance Information
, order number SA33-3285.
