Rebuilding a mirrored disk array

Escalade ATA RAID Controllers allow you to create fault tolerant disk arrays
by selecting a mirrored RAID 1 or RAID 10 array. These disk arrays store
identical data on two or more drives to protect against drive failure. If one or
more of the drives of a mirrored array is removed, unplugged or fails on read
or write requests, the array is marked as DEGRADED and the drive is
marked as Not In Use or is not displayed if no longer available. (see
Figure 18 and Figure 19).
You can still read and write data from a degraded disk array, but the array will
not be fault tolerant until it is rebuilt using the Rebuild feature, described in
the 3ware Disk Array Configuration Utility or 3DM Disk Management Utility
chapters, or until it is automatically rebuilt using a previously created hot
spare.
