Creating an Array

A RAID 5 array is created in the examples shown in this section because RAID 5

provides the most security and best performance with a minimum of three disk

drives. However, you can choose to create an array with a different RAID level; you

can also change array level later, after the operating system is installed.

You can create an array using either of these tools:

■ Array Configuration Utility (ACU)—BIOS-based menus and keyboard

navigation. See “To Create a RAID 5 Array With the ACU” on page 29.

■ Command Line Interface (UCLI)—Refer to the Uniform Command-Line Interface

User’s Guide at the following website:

http://docs.sun.com/app/docs/prod/stortek.raid.hba#hic

You can use either tool, but the ACU utility is the quicker and easier tool for this

task. The ACU is menu-based and provides instructions for completing tasks on-

screen. Menus can be navigated using the arrows, Enter, Esc, and other keys on your

keyboard.

Note – Do not combine SAS and SATA disk drives within the same array. The Sun

StorageTek RAID Manager software generates a warning if you try to create a logical

drive using a combination of SAS and SATA disk drives. See “Introduction to Serial

Attached SCSI” on page 103 for more information.
