Rebuilding A Mirrored Disk Array; Figure 15. Degraded Raid 1 Array Drive When Not In Use - 3Ware 3W-6800 User Manual

Rebuilding a mirrored disk array

Escalade Storage Switches 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
(see Figure 15 and Figure 16).
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.
