CLI Command Descriptions
SET FAILEDSET
Enables changes to the automatic replacement policy for the failedset.
Syntax
SET FAILEDSET
Parameters
There are no parameters associated with this command.
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 device (one that has not been
initialized). 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 initializes the disk and
moves it 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 (if it was used in a stripeset or was
initialized as NOTRANSPORTABLE), you must use the following procedure to
make the disk available as a spareset replacement disk (DISK10000 is used as an
example):
1. Delete all containers to which the disk belongs.
