Creating and Managing Arrays and Partitions
Using the Disk Array Administrator, the user can create and manage arrays and partitions.
The following array-related functions can be performed:
• Create arrays
• Manage arrays
• Manage partitions
Creating Arrays
NOTE: Before creating more than one array, make sure that the host operating system
supports multiple LUNs. Most operating systems do, or have an option to enable
multiple LUN support. If the host system does not support multiple LUNs, the host
will only see one array at LUN 0.
An array can be created at anytime. Table 4 below describes the drive requirements for each
RAID level.

Table 4: Drive Requirements for each RAID Level
Before an array is created, the user must decide whether or not to partition the array. There
are two (2) ways to partition an array:
1. Single-partition array - an array that stores all data in a single partition and is ac-
cessed by a single LUN.
2. Multiple-partition array - an array that can have one or more partitions, with each
partition assigned its own LUN.
Refer to section "Understanding Partitions" for further information.
