unmirrorios command
Purpose
Removes the mirrors that exist on the rootvg volume group.
Syntax
unmirrorios [ PhysicalVolume ...]
Description
The unmirrorios command unmirrors all the logical volumes detected on the rootvg volume group. By default, unmirrorios picks the set of mirrors to remove from a mirrored volume group. To control which drives no longer are to contain mirrors, you must include the list of disks in the input parameters, PhysicalVolume.
At the completion of this command, Quorum is disabled until the system is rebooted.
Note: If LVM has not recognized that a disk has failed, it is possible that it removes a different
mirror. If you know that a disk has failed, and LVM does not show those disks as missing, you must
specify the failed disks on the command line or you must use the reducevg command to remove
the disk.
