Images of disks in RAID recovery

In RAID recovery, if there is a controller failure, or a known software failure, there is no need to create the images of the RAID member disks. In single-disk operations, it is often considered a good practice to always make an image a disk. With RAID, this may be not so easy, considering sheer size of the modern arrays.

Actually, if there is no reason to suspect the physical damage of the RAID member disks, the imaging may be skipped altougether or put off until the decision is made to modify the data on the disks (possibly to revive the controller metadata).
