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

Planning Storage 2–21
Changing Characteristics through
Switches
CLI command switches allow the user another level of command options. There are three
types of switches that modify the storageset and unit characteristics:
■ Storageset switches
■ Initialization switches
■ Unit Switches
The following sections describe how to enable/modify switches. They contain a
description of the major CLI command switches.
Enabling Switches
If you use SWCC to configure the device or storageset, you can set switches from the
SWCC screens during the configuration process, and SWCC automatically applies
them to the storageset or device. See the SWCC help online for information about
using SWCC.
If you use CLI commands to configure the storageset or device manually, the
configuration procedure found in Chapter 5 of this guide indicates when and how to
enable each switch. The Compaq StorageWorks HSG60 Array Controller ACS Version
8.6 CLI Reference Guide contains the details of the CLI command and their switches.
Changing Switches
You can change the RAIDset, mirrorset, device, and unit switches at any time. You
cannot change the initialize switches without destroying the data on the storageset or
device. These switches are integral to the formatting and can only be changed by
re-initializing the storageset.
CAUTION: Initializing a storageset is similar to formatting a disk drive; all of the data
is destroyed during this procedure.
