cli_unmirrorvg command

Purpose

Unmirror a volume group on all nodes in a cluster.

cli_unmirrorvg  [ -c Copies ] VolumeGroup [ PhysicalVolume ... ]

Uses C-SPOC to run the unmirrorvg command with parameters, and make the updated volume group definition available on all cluster nodes.

-c Copies: Specifies the minimum number of copies that each logical volume must have after you run the unmirrorvg command. If you do not want all logical volumes to have the same number of copies, then reduce the mirrors manually with the rmlvcopy command. If you do not use this flag, the default value of 1 is used.

To specify a single copy for shared volume group that is named vg01, enter:

cli_unmirrorvg -c 1 vg01
