vgreduce(8)
NAME
  vgreduce - Reduce a volume group by removing one or more physical volumes
  from it

SYNOPSIS
  /usr/sbin/vgreduce VolumeGroupName PhysicalVolumePath ...

DESCRIPTION
				     Note

       This command is no longer supported on Digital UNIX systems.
       Features formerly provided by the Logical Volume Manager (LVM)
       are now provided by the Logical Storage Manager (LSM).  Existing
       LVM volumes must be migrated to LSM, using an encapsulation
       process.	 For information about moving LVM volumes to LSM, see
       the vollvmencap(8) reference page and the manual Logical Storage
       Manager.

  The vgreduce command removes the physical volume(s) specified with the
  PhysicalVolumePath parameter from VolumeGroupName.

  All but one physical volume can be removed.  The last physical volume must
  remain in the volume group so that the logical volume driver can continue
  to operate.  The last physical volume in the volume group is removed by the
  vgremove command.

  All logical volumes residing on the physical volume(s) represented by the
  PhysicalVolumePath parameter must be removed by executing the lvremove
  command before executing the vgreduce command.

EXAMPLES
  To remove physical volume hdisk1 from volume group vg01, enter:

       vgreduce	 /dev/vg01  /dev/hdisk1

  The physical volume hdisk1 no longer belongs to volume group vg01.

  To remove physical volume rz1c from volume group vg01, enter:

       vgreduce	 /dev/vg01  /dev/rz1c

  The physical volume rz1c no longer belongs to volume group vg01.
