Planning Storage Configurations
92 HSG80 ACS Solution Software V8.8 for Tru64 UNIX Installation and Configuration Guide
Caution: If user data already exists on a storageset, do NOT reinitialize it with
the
save configuration option, as this will change the site and position of the
user data on the storageset. Always back up user data prior to reinitializing
any storageset.
The SHOW DEVICES FULL command shows which disks are used to backup
configuration information.
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.
