Capacity Expansion

Capacity expansion involves adding storage capacity to an array that has

already been configured. If an existing array is nearly full of data, you can

expand the capacity without disturbing the existing data. The RA4000

controller capacity expansion feature allows new physical drives to be added

to the array.

When the Array Configuration Utility runs, the program checks the drive

hardware and configuration. If the Array Configuration Utility discovers a

physical drive that is not being used, the configuration wizard leads you

through the steps for adding the drive.

Expanding Array Capacity—Procedure

To bypass the configuration wizard:

1. Install the new physical drives.

NOTE: Always group physical drives of the same size. If you mix drive sizes, the capacity

of the larger drives is wasted.
