Use this MAP to resolve the following problems:
- Incompatible disk is installed at the degraded disk location in
the disk array (SRN nnnn-9025) for PCIe2 or PCIe3 controllers.
- Disk array is degraded due to a missing or failed disk (SRN nnnn -
9030) for PCIe2 or PCIe3 controllers.
- Automatic reconstruction was initiated for a disk array (SRN nnnn -
9031) for PCIe2 or PCIe3 controllers.
- Disk array is degraded due to a missing or failed disk (SRN nnnn -
9032) for PCIe2 or PCIe3 controllers.
Step 3210-1
Identify the disk array by examining
the hardware error log.
- Follow the steps in Examining the hardware error log and return here.
- Select the hardware error log to view. This error log displays
the following disk array information under the heading Array Information:Resource, S/N (serial
number), and RAID Level.
- Go to Step 3210-2.
Step 3210-2
View the current
disk array configuration as follows:
- Start the IBM® SAS Disk Array Manager.
- Start AIX diagnostics and
select Task Selection on the Function Selection
display.
- Select .
- Select List SAS Disk Array Configuration.
- Select the IBM SAS RAID
controller that is identified in the hardware error log.
- Go to Step Step 3210-3.
Step 3210-4
The affected
disk array has a state of either Rebuilding or Optimal due
to the use of a hot spare disk.
Identify the failed disk,
which is no longer a part of the disk array, by finding the pdisk
listed at the bottom of the display that has a state of either Failed or RWProtected.
Using appropriate service procedures, such as use of the SCSI and
SCSI RAID Hot Plug Manager, remove the failed disk and replace it
with a new disk to use as a hot spare. See the Replacing pdisks section for this procedure,
and then continue here.
Return to the List SAS Disk Array Configuration
display in the IBM SAS Disk
Array Manager. If the new disk is not listed as a pdisk, it might
first need to be prepared for use in a disk array. Do the following
steps:
- Start the IBM SAS Disk Array Manager.
- Start AIX diagnostics and
select Task Selection on the Function Selection
display.
- Select .
- Select Create an Array Candidate pdisk and Format to
528 Byte Sectors.
- Select the appropriate IBM SAS
RAID controller.
- Select the disks from the list that you want to prepare for use
in the disk arrays.
To make the new disk usable as a hot spare, complete the following
steps:
- Start the IBM SAS Disk Array Manager.
- Start AIX diagnostics and
select Task Selection on the Function Selection
display.
- Select .
- Select .
- Select the IBM SAS RAID
controller.
- Select the pdisk that you want to designate as a hot spare.
Note: Hot spare disks are useful only if their capacity is greater
than or equal to that of the smallest capacity disk in a disk array
that becomes degraded.
When the problem is resolved, see the removal and replacement
procedures topic for the system unit on which you are working and
do the "Verifying the repair" procedure.
Step 3210-5
Identify the
failed disk by finding the pdisk listed for the degraded disk array
that has a state of
Failed. Using appropriate service procedures,
such as the SCSI and SCSI RAID Hot Plug Manager, remove the failed
disk and replace it with a new disk to use in the disk array. Refer
to the
Replacing pdisks section for this
procedure, and then continue here.
Note: The replacement disk must have a capacity
that is greater than or equal to that of the smallest capacity disk
in the degraded disk array.
To bring the disk array back
to a state of Optimal, complete the following steps:
- Start the IBM SAS Disk Array Manager.
- Start Diagnostics and select Task Selection on
the Function Selection display.
- Select .
- Select Reconstruct a SAS Disk Array.
- Select the failed pdisk to reconstruct.
When the problem is resolved, see the removal and replacement
procedures topic for the system unit on which you are working and
do the "Verifying the repair" procedure.
