3 Configuring a Storage Array This chapter explains how to run script commands from the command line to create a virtual disk from a group of physical disks and how to configure a redundant array of independent disks (RAID) storage array. This chapter assumes that you understand basic RAID concepts and terminology. Before configuring the storage array, become familiar with the concepts of physical disks, disk groups, virtual disks, host groups, hosts, and RAID controller modules. Additional information about configuring a storage array and related definitions is in the online help, the Deployment Guide, the MD Storage Manager online help, and the Owner's Manual. Configuring a RAID storage array requires caution and planning to ensure that you define the correct RAID level and configuration for your storage array. The main purpose in configuring a storage array is to create virtual disks addressable by the hosts from a collection of physical disks. The commands described in this chapter enable you to set up and run a RAID storage array. Additional commands are also available to provide more control and flexibility. Many of these commands, however, require a deeper understanding of the firmware as well as various structures that need to be mapped. Use all of the command line interface (CLI) commands and script commands with caution. The following sections in this chapter show some, but not all, of the CLI and script commands. The purpose of showing these commands is to explain how you can use the commands to configure a storage array. The presentation in this chapter does not explain all possible usage and syntax for the commands. (For complete definitions of the commands, including syntax, parameters, and usage notes, see "Script Commands" on page 105.) This chapter contains examples of CLI and script command usage. The command syntax used in the examples is for a host running a Microsoft Windows operating system. As part of the examples, the complete C:\ prompt and DOS path for the commands are shown. Depending on your operating system, the prompt and path construct varies. For most commands, the syntax is the same for all Windows and Linux operating systems, as well as for a script file. Windows operating systems, however, have an additional requirement when entering names in a Configuring a Storage Array 43
