SRN Problem Possible Causes
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.
Possible FRUs:
Device (90%) (“Exchanging
Disk Drives” on page 319).
SSA adapter card (10%)
(“Removing and Replacing
an Advanced SerialRAID
Adapter” on page 327).
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.
Possible FRUs:
Device (100%)
(“Exchanging Disk Drives”
on page 319).
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.
Possible FRUs:
Device (40%) (“Exchanging
Disk Drives” on page 319).
SSA adapter card (40%)
(“Removing and Replacing
an Advanced SerialRAID
Adapter” on page 327).
External SSA cables,
Fibre-Optic Extenders,
fiber optic cables, or
internal connections in
the device enclosure
(20%) (enclosure service
information).
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.
v For a RAID-0 or a
RAID-Copy array, at least
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.
