Are any disk drives listed as "SSA physical disks that are rejected"?
NO
YES

User's Guide and Maintenance Information
A disk drive has not been detected by the adapter. Go to step 19 on
page 465.
a. Run diagnostics in System Verification mode to all the disk drives that
are listed as rejected.
b. Run the Certify service aid (see "Certify Disk Service Aid" on
page 391) to all the disk drives that are listed as rejected.
c. If problems occur on any disk drive, exchange that disk drive for a
new disk drive (see "Exchanging Disk Drives" on page 319), then
continue from step 18e in this procedure.
d. A disk drive that is listed as rejected is not necessarily failing. For
example, the array might have rejected the disk drive because a
power problem, or an SSA link problem, caused that drive to become
temporarily unavailable. Under such conditions, the disk drive can be
reused.
If you think that a disk drive has been rejected because it is failing,
check the error log history for that disk drive. For example, if you
suspect pdisk3, type on the command line:
This command causes the error log for pdisk3 to be analyzed for the
previous five days. If a problem is detected, an SRN is generated.
e. Type
f. Select Change/Show Use of an SSA Physical Disk and, for all disks
that you have tested or exchanged, change the Current Use to Array
Candidate Disk.
g. Select Change Member Disks in an SSA RAID Array.
h. Select Swap Members of an SSA RAID Array.
i. Select the degraded hdisk.
j. Referring to the displayed instructions, exchange the failed member for
a new disk drive. (The Disk to Remove is listed as BlankReserved;
the Disk to Add is the disk drive that you tested or exchanged in step
18f.) When failed disk drives have been exchanged for new disk
drives, the data is rebuilt, and the array changes its state to the Good
state.
Note: The array can be used during the rebuilding operation. Inform
the user, however, that while the rebuilding operation is running,
the data is not protected against another disk drive failure. The
rebuilding operation runs more slowly if the array is being used.
