 Paused– Temporary pause while another background activity runs. Or a
pause initiated by the user.

Redundancy Check

Redundancy Check is a routine maintenance procedure for fault-tolerant
disk arrays (those with redundancy) that ensures all the data matches
exactly. Redundancy Check can also correct inconsistencies.

Rebuild

When you rebuild a disk array, you are actually rebuilding the data on one
physical drive.
When a physical drive in a disk array fails and a spare drive of adequate
capacity is available, the disk array begins to rebuild automatically using
the spare drive.
If there is no spare drive of adequate capacity, but the Auto Rebuild
function is ENABLED, the disk array begins to rebuild automatically as
soon as you remove the failed physical drive and install an un-configured
physical drive in the same slot.
If there is no spare drive of adequate capacity and the Auto Rebuild
function is DISABLED, you must replace the failed drive with an
un-configured physical drive, perform a Manual Rebuild. See below.
If your replacement physical drive was formerly part of a
different disk array or logical drive, you must clear the
configuration data on the replacement drive before you
use it.

Migration

The term Migration means either or both of the following actions:
 Change the RAID level of a logical drive.
 Expand the storage capacity of a logical drive.
Before you begin a migration, examine your current disk array to
