Array Synchronization

Access array synchronization using the Array pull-down menu (see above sec-
tion). Synchronization is a periodic maintenance procedure for Mirroring
(RAID 1, RAID 0+1) arrays to maintain data consistency on all mirrored dri-
ves. In operation, array synchronization compares data on the mirrored drives
for any differences. If there are differences detected, data from the primary
drive(s) is automatically copied to the secondary drive(s). This assures that all
mirrored drives will contain the exact information.
