Inconsistent
The member disk drives in the pool do not agree about the size of the hot
spare disk drives, or about the minimum number of hot spare disk drives that
is required.
This state is probably caused by changes to the SSA loop; for example, the
addition of disk drives or changes to the SSA cabling. If you did not intend to
make such changes, and you correct them, the pool returns to its original
state.
If you did intend to make the changes:
1. Select Change/Show/Delete a Hot Spare Pool from the smit ssaraid
menu (see “Adding Disks to, or Removing Disks from, a Hot Spare Pool”
on page 86).
2. Select the reduced hot spare pool.
3. Verify that the contents of the pool are as required.
4. Press Enter.
Mixed An array in this pool has used a hot spare disk drive from another pool.
When replacement disk drives are installed in exchange for failed disk drives,
the replacement disk drives are assigned as hot spare disk drives or as free
disk drives. The hot spare pools, however, are no longer configured as
intended. To correct the configuration:
1. Select List Components in a Hot Spare Pool (see “Listing the Disks That
Are in a Hot Spare Pool” on page 80).
2. Select the mixed hot spare pool.
3. From the displayed list, note the number of the pdisk that has a status of
wrong_pool.
4. Note the number of the hdisk to which the pdisk belongs.
5. Select Swap Member Disks in an SSA RAID Array (see “Changing
Member Disks in an SSA RAID Array” on page 137).
6. Select the hdisk that you noted in step 4.
The Disk to Remove is the pdisk that you noted in step 3.
The Disk to Add is the replacement disk drive that was installed in
exchange for the failed disk drive.
Unused
Hot spare disk drives exist in a pool, but they are not protecting any member
disk drive.
This condition does not cause an error to be logged.
If required, you can move hot spare disk drives from this pool to a pool that
contains RAID arrays. Alternatively, you can change the use of hot spare disk
drives that are in this pool.
