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 24e 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 disk
drives that you have tested or exchanged, change the Current Use
parameter 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 hdisk that is in the Degraded copy state (that is, the hdisk
that you noted in step 23d on page 467).
j. Referring to the displayed instructions, select a disk drive to remove
from the array, and the disk drive to add to the array. (The disk drive to
remove is listed as not_present; the disk drive to add is the disk drive
that you tested or exchanged in the previous steps.) When the
exchange is complete, the array starts to copy its data to the coupled
disk drive.
k. Go to "MAP 2410: SSA Repair Verification" on page 475 to verify the
repair.
Does the Link Verification service aid indicate an open loop?
NO
Go to step 26.
YES
Go to "MAP 2320: SSA Link" on page 445.
Does any SSA disk drive have its Check light on?
NO
The disk drive might have been removed from the subsystem.
a. Reinstall the removed drive, or select a new disk drive for addition to
the array.
b. Type
c. Select Change/Show Use of an SSA Physical Disk. The pdisk that
has been exchanged is listed under SSA Physical Disks that are
system disks.
