NAMEdrd_unregister_mirror — notify DRD that an LVM or VxVM mirror of a system image is about to be manually removed DESCRIPTIONThe 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. EXAMPLESTo display drd_unregister_mirror usage information: drd_unregister_mirror -?
