Planning Storage Configurations
2–28 HSG80 ACS Solution Software Version 8.7 for Compaq Tru64 UNIX Installation and
Configuration Guide
The following sections describe how to enable/modify switches. They also 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
SWCC during the configuration process, and SWCC automatically applies them to the
storageset or device. See the SWCC online help 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 StorageWorks HSG80 Array Controller ACS Version 8.7 CLI
Reference Guide contains the details of the CLI commands 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 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 data is
destroyed during this procedure.
Specifying Storageset and Partition Switches
The characteristics of a particular storageset can be set by specifying switches when
the storageset is added to the controllers’ configuration. Once a storageset has been
added, the switches can be changed by using a
SET command. Switches can be set for
partitions and the following types of storagesets:
• RAIDset
• Mirrorset
Stripesets have no specific switches associated with their ADD and SET commands.
RAIDset Switches
Use the following types of switches to control how a RAIDset ensures data
availability:
