SRN
Problem
43PAA Description: An SSA device on the link is preventing the completion of the
loop configuration.
Action: If the SSA service aids are available, run the Link Verification
|
service aid (see "Link Verification Service Aid" on page 383) to determine
|
which device is preventing configuration. (That device is the one beyond
|
the last-configured device on an open SSA loop.)
|
If the SSA service aids are not available, note the value of PAA in this
SRN, and go to "Finding the Physical Location of a Device" on page 409.
44PAA Description: An SSA device has a 'Failed' status.
Action: If the SSA service aids are available, run the Link Verification
service aid (see "Link Verification Service Aid" on page 383) to find the
failing device. If no device is listed with a status of "Failed", use the PAA
part of the SRN to determine which device is failing. Before you exchange
the failing device, run diagnostics in System Verification mode to that
device to determine the cause of the problem.
If the SSA service aids are not available, note the value of PAA in this
SRN, and go to "Finding the Physical Location of a Device" on page 409.
Exchange the failing FRU for a new FRU.
45PAA Description: The SSA adapter has detected an open SSA loop.
Action: If the SSA service aids are available, run the Link Verification
service aid (see "Link Verification Service Aid" on page 383) to determine
|
which part of the SSA loop is failing.
|
|
If the SSA service aids are not available, note the value of PAA in this
|
SRN, and go to "Finding the Physical Location of a Device" on page 409.
Then go to "SSA Link Errors" on page 478 to solve the problem.

46000
Description: An array is in the Offline state because not enough disk
|
|
drives are present in the array to maintain data availability.
|
|
|
Action: If the SSA service aids are available, run the Link Verification
|
|
service aid (see "Link Verification Service Aid" on page 383) to find power
|
|
faults or broken SSA links that might be causing this problem.
|
|
|
If the SSA service aids are not available, or the problem remains, go to
|
|
"MAP 2324: SSA RAID" on page 454 to isolate the problem.

Possible FRUs:
Device (40%) ("Exchanging
Disk Drives" on page 319).
SSA adapter card (40%)
("Removing and Replacing
an Advanced SerialRAID
Adapter" on page 327).

one member disk drive of the
array is missing.
v For a RAID-5 array, at least
two member disk drives
cannot be accessed.
v For a RAID-10 array, at least
one mirrored pair of disk
drives cannot be accessed.
v Power problem.
v System configuration
problem.
