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 nontransportable 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
4. Verify the configuration:
SHOW STORAGESET-NAME
Changing Switches for a Storageset or Device
You can optimize a storageset or device at any time by changing the switches that are
associated with it. Remember to update the storageset profile when changing its
switches.
