Compaq StorageWorks HSG60 ACS Solution Software V8.6 for Compaq Tru64 UNIX Installation and Configuration Guide

Configuration Procedures 5–23
During initialization, AUTOSPARE checks to see if the new disk drive contains metadata.
Metadata is information the controller writes on the disk drive when that the disk drive is
configured into a storageset. Therefore, the presence of metadata indicates 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, 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's profile when you change its
switches.
Displaying the Current Switches
To display the current switches for a storageset or single-disk unit, enter a SHOW
command, specifying the FULL switch:
SHOW STORAGESET-NAME
or
SHOW DEVICE-NAME FULL
