drd_unregister_mirror(1M)drd_unregister_mirror(1M)NAMEdrd_unregister_mirror - notify DRD that an LVM or VxVM mirror of a
system image is about to be manually removed.
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 comand can be run before or after the mirror
is actually removed, but there are some benefits to running drd_unreg‐
ister_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.
