SRN Problem Possible Causes
49950 Description: An array copy disk drive is missing. The array copy is
degraded. If the missing disk drive is restored to the network or
exchanged for a new disk drive, the copy rebuilds. A disk drive might not
be available for one of the following reasons:
v
The disk drive has failed.
v
The disk drive has been removed from the subsystem.
v
An SSA link has failed.
v
A power failure has occurred.
Action: Go to “MAP 2324: SSA RAID” on page 454.
Possible FRUs:
Device (100%)
(“Exchanging Disk Drives”
on page 319).
4A100 Description: The adapter cannot initialize a disk drive. The failing disk
drive might, or might not, be configured on this system.
Action: Run diagnostics in System Verification mode to all pdisks.
If the diagnostics fail, exchange the pdisk for a new disk drive.
If the diagnostics do not detect a failing pdisk, use the Link Verification
service aid (see “Link Verification Service Aid” on page 383) to search for
disk drives that are not configured. Such disk drives are listed as *****.
Note: Other adapters in the SSA loop might also be listed as *****.
Exchange, for new disk drives, all pdisks that are not configured.
Possible FRUs:
Device (100%)
(“Exchanging Disk Drives”
on page 319).
4BPAA Description: A disk drive at PAA cannot be configured, because its UID
cannot be read.
Action: If the SSA service aids are available:
1. Run the Link Verification service aid (see “Link Verification Service
Aid” on page 383) to find the failing device. The service aid lists the
device as
*****
.
2. Exchange the FRU for a new FRU.
If the service aids are not available:
1. Note the value of PAA in this SRN, then go to “Finding the Physical
Location of a Device” on page 409.
2. Exchange the FRU for a new FRU.
Possible FRUs:
Device (100%)
(“Exchanging Disk Drives”
on page 319).
50000 Description: The SSA adapter failed to respond to the device driver.
Action: Exchange the FRU for a new FRU.
Possible FRUs:
SSA adapter card (100%)
(“Removing and Replacing
an Advanced SerialRAID
Adapter” on page 327).
50001 Description: A data parity error has occurred.
Action: Exchange the FRU for a new FRU.
Possible FRUs:
SSA adapter card (100%)
(“Removing and Replacing
an Advanced SerialRAID
Adapter” on page 327).
