NOTE: The RUN CONFIG command does not delete disks from the controllers’ device table if a
disk has been physically removed or replaced. In this case, you must use the command:
DELETE DISKNNNN.
3. Verify the contents of the spareset by entering the following command:
SHOW SPARESET
Enabling Autospare
With AUTOSPARE enabled on the failedset, any new disk drive that is inserted into the
PTL location of a failed disk drive is automatically initialized and placed into the spareset.
If initialization fails, the disk drive remains in the failedset until you manually delete it
from the failedset.
To enable autospare, use the following command:
SET FAILEDSET AUTOSPARE
To disable autospare, use the following command:
SET FAILEDSET NOAUTOSPARE
During initialization, AUTOSPARE checks to see if the new disk drive contains metadata.
Metadata is information the controller writes on the disk drive when the disk drive is
configured into a storageset. Therefore, the presence of metadata indicates that the disk
drive belongs to, or has been used by, a storageset. If the disk drive contains metadata,
initialization stops. (A new disk drive will not contain metadata but a repaired or reused
disk drive might. To erase metadata from a disk drive, add it to the controller's list of
devices, then set it to be notransportable and initialize it.)
Deleting a Storageset
NOTE: If the storageset you are deleting is partitioned, you must delete each partitioned unit
before you can delete the storageset.
1. Show the storageset’s configuration:
SHOW STORAGESET-NAME
2. Delete the unit number that uses the storageset. Use the following command:
DELETE UNIT-NUMBER
3. Delete the storageset. Use the following command:
DELETE STORAGESET-NAME
