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.
