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 will pick 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 will be disabled until the system is rebooted.

Note:

If LVM has not recognized that a disk has failed, it is possible that it will remove a different mirror. If you know that a disk has failed, and LVM does not show those disks as missing, you should specify the failed disks on the command line or you should use the reducevg command to remove the disk.

Exit Status

See Virtual I/O Server command exit status.

Security

This command can only be executed by the prime administrator.
