Chapter 4. Configuring a Storage Subsystem

Before using script commands to manage a storage subsystem, you should be familiar with these items:
v Controllers
v Disk drives
v Hot spares
v subsystems
v Logical drives
v Disk pools
v RAID technology
v Hosts
v Host groups
v Host bus adapter (HBA) host ports
v Logical unit numbers (LUNs)
Configuring a RAID storage subsystem requires caution and planning to make sure that you define the
correct RAID level and configuration for your storage subsystem. You configure a storage subsystem to
create logical drives, which are addressable by the hosts, from a collection of disk drives. The commands
described in this chapter help you to set up and run a RAID storage subsystem. Additional commands
are also available to provide you with more control and flexibility.
Note: Many of these commands require a thorough understanding of the firmware as well as an
understanding of the network components that need to be mapped. Use the CLI commands and the
script commands with caution.
The sections in this chapter show some, but not all, of the CLI commands and the script commands. The
commands in this chapter show how you can use the commands to configure a storage subsystem. These
presentations do not describe all possible usage and syntax for the commands. (For complete definitions
of the commands, including syntax, parameters, and usage notes, see Chapter 3, "Script Commands," on
page 3-1.
This chapter contains examples of CLI command usage and script command usage. The command syntax
that is used in the examples is for a host running a Microsoft operating system. As part of the examples,
the complete C:\ prompt and the DOS path for the commands are shown. Depending on your operating
system, the prompt and path construct will vary.
For most commands, the syntax is the same for all Windows operating systems and UNIX operating
systems, as well as for a script file. Windows operating systems, however, have an additional requirement
when entering names in a command. On Windows operating systems, you must enclose the name
between two back slashes (\ \) in addition to other delimiters. For example, the following name is used
in a command running under a Windows operating system:
[\"Engineering\"]
For a UNIX operating system, and when used in a script file, the name appears as follows:
["Engineering"]
