8. Repeat the procedure given above for any other disk drive that you are changing.

Exchanging an Array Disk
This section describes how a disk is logically removed from an array and replaced by a
compatible Free Resource. Such action could be necessay, for example, to check a
disk drive that is giving a high level of read/write errors but has not been rejected from
the array.
This action is also necessary if an array disk develops a hard fault and there is no
hot-spare available. If this happens, at the next write operation the faulty disk is
automatically de-configured and moved to the Rejected list. In the array, the faulty disk
is replaced by a Blank Reserved. To restore the array to its full operational status you
need to replace the Blank Reserved in the array with a suitable Free Resource.
Note: If there was a Hot-Spare available when the array disk became faulty the
hot-spare is automatically integrated into the array and the faulty disk moved to the list
of Rejected disks. The procedure in this event is to convert the Rejected disk to a Free
resource, then change it as described in “Exchanging a Non-Array Disk Drive” on
page 19. The new disk can then be reassigned as a Hot-Spare to replace the one that
was used.
