SET FAILEDSET
Changes the automatic replacement policy for the failedset.
Syntax
SET FAILEDSET
Switches
AUTOSPARE
NOAUTOSPARE
Specifies the policy to be used by the controller when a disk drive is physically
replaced in the failedset.
Specify AUTOSPARE to instruct the controller to automatically move devices
physically replaced in the failedset into the spareset.
Specify NOAUTOSPARE to instruct the controller to leave devices physically
replaced in the failedset. The device, though replaced, remains in the failedset until it
is manually removed with the DELETE FAILEDSET command.
In most circumstances, a disk physically replaced into the failedset is functional and
contains no metadata—that is, a new, initialized device. If you specify the
AUTOSPARE switch when a disk is physically replaced in the failedset, the
controller checks to see if any metadata is present. If the controller detects metadata,
the disk remains in the failedset. If the controller does not detect metadata, the
controller automatically moves the disk from the failedset to the spareset. Now a
member of the spareset, the disk is available for any mirrorset or RAIDset requiring a
replacement member. If the automatic initialization fails, the disk remains in the
failedset.
Disks that you plan to use for AUTOSPARE must not have valid metadata on them. If
you suspect a disk does have metadata on it (it was used in a stripeset or was
initialized as NOTRANSPORTABLE) you must use the following steps to make the
disk available as a spareset replacement disk:
