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.
