NAME
drd_unregister_mirror - notify DRD that an LVM or VxVM mirror of a system image is about to be manu-
ally removed
SYNOPSIS
drd_unregister_mirror
[-?] mirror_block_device_file
DESCRIPTION
The
drd_unregister_mirror
command notifies DRD that a mirror of either the active system image
or the inactive sytem image has been removed or is about to be removed.
The
drd_unregister_mirror
command can be run before or after the mirror is actually removed,
but there are some benefits to running
drd_unregister_mirror
first: You CANNOT remove the disk
that DRD identifies as the boot disk of a system image. The
drd_unregister_mirror
command will
exit with a failure return code if you attempt to do so. If you are not sure which mirrored copy of a system
image is identified by DRD as the boot disk, run
drd_unregister_mirror
to attempt to remove the
disk. If you have chosen the boot disk, the command will fail. The other disk can then be unregistered and
removed.
