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.
SYNOPSIS
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 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.

the disk have been removed or are about to be removed.
