Note: DO NOT use SAVE_CONFIGURATION in dual redundant controller
installations. It is not supported and may result in unexpected controller behavior.
Note: HP recommends that you do not use SAVE_CONFIGURATION on every unit
and device on the controller.
Destroy/Nodestroy
Specify whether to destroy or retain the user data and metadata when a disk is
initialized after it has been used in a mirrorset or as a single-disk unit.
Note: The DESTROY and NODESTROY switches are only valid for mirrorsets and
striped mirrorsets.
■ DESTROY (default) overwrites the user data and forced-error metadata when a
disk drive is initialized.
■ NODESTROY preserves the user data and forced-error metadata when a disk
drive is initialized. Use NODESTROY to create a single-disk unit from any
disk drive that has been used as a member of a mirrorset. See the
REDUCED
command in the HP StorageWorks HSG60 and HSG80 Array Controller and
Array Controller Software Command Line Interface (CLI) Reference Guide
for information on removing disk drives from a mirrorset.
NODESTROY is ignored for members of a RAIDset.
Geometry
The geometry parameters of a storageset can be specified. The geometry switches
are:
■ CAPACITY—the number of logical blocks. The range is from 1 to the
maximum container size.
■ CYLINDERS—the number of cylinders used. The range is from 1 to
16777215.
■ HEADS—the number of disk heads used. The range is from 1 to 255.
