HSG80 ACS Solution Software V8.6 for Windows NT and Windows 2000 Installation and Configuration Guide

2–28 HSG80 ACS Solution Software Version 8.6 for Windows NT and Windows 2000 Installation and
Configuration Guide
Save Configuration
The SAVE CONFIGURATION switch is for a single-controller configuration only. This
switch reserves an area on each of the disks that constitutes the container being initialized.
The controller can write subsystem configuration data on this area. If the controller is
replaced, the new controller can read the subsystem configuration from the reserved areas
of disks.
If you specify SAVE_CONFIGURATION for a multi-device storageset, such as a stripeset,
the complete subsystem configuration is periodically written on each disk in the
storageset.
The
SHOW DEVICES FULL command shows which disks are used to backup configuration
information.
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 Compaq
StorageWorks HSG80 Array Controller ACS Version 8.6 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.
