SRN Problem Possible Causes
49500 Description: No hot spare disk drives are available for an array that is
configured for hot spare disk drives.
Action: Determine whether any disk drives have failed or have been
rejected. To do this action:
1. Display the use of the disk drives that are attached to the SSA
adapter that logged the error (see “Changing or Showing the Use of
an SSA Disk Drive” on page 144).
2. Run diagnostics in Problem Determination mode to all pdisks that
are attached to the adapter that logged this error.
3. If any disk drives have failed, first exchange those disk drives for
new disk drives, and assign them to the use that has been specified
by the user. If the problem remains, continue with the next step.
4. Type smitty ssaraid and press Enter.
5. Select List Status of Hot-Spare Protection for an SSA RAID
Array.
6. Select the adapter that logged the error.
7. Observe the displayed list. Note which SSA loop contains any array
member disk drives that are listed with a protected state of no.
Devices that are in pool_A0 are connected to loop A. Devices that
are in pool_B are connected to loop B.
8. If the status field for the unprotected array member disk drive is
too_large, the hot spare disk drive is not large enough to support
that array component. Otherwise, no hot spare disk drive exists on
the loop that you noted earlier.
9. Return to the SSA RAID Arrays menu and select Change/Show Use
of an SSA Physical Disk.
10. Select the adapter that logged the error.
11. Find an appropriate disk drive, and change its use to hot spare (see
“Changing or Showing the Use of an SSA Disk Drive” on page 144).
A RAID array is configured to
use hot spare disk drives, but
no disk drive can be found that
is configured as a hot spare.
This error code is used only
when no hot spare pools have
been assigned. All arrays and
hot spare disk drives are in the
default pool0.
