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.
|
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.
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.
50000

|
Action: Exchange the FRU for a new FRU.
