To remove all VxVM objects from an imported source disk group to an imported target disk group, use the following command:
# vxdg [-o override|verify] join sourcedg targetdg
The following output from vxprint shows the contents of the disk groups rootdg and mydg.
The output includes two utility fields, TUTIL0 and PUTIL0.. VxVM creates these fields to manage objects and communications between different commands and Veritas InfoScale products. The TUTIL0 values are temporary; they are not maintained on reboot. The PUTIL0 values are persistent; they are maintained on reboot.

The following command joins disk group mydg to rootdg:
# vxdg join mydg rootdg
By default, VxVM automatically recovers and starts the volumes following a disk group join. If you have turned off the automatic recovery feature, volumes are disabled after a join. Use the following commands to recover and restart the volumes in the target disk group:
# vxrecover -g targetdg -m [volume ...] # vxvol -g targetdg startall
The output from vxprint after the join shows that disk group mydg has been removed:
# vxprint Disk group: rootdg TY NAME ASSOC KSTATE LENGTH PLOFFS STATE TUTIL0 PUTIL0 dg rootdg rootdg - - - - - - dm mydg01 sda - 17678493 - - - - dm rootdg02 sdb - 17678493 - - - - dm rootdg03 sdc - 17678493 - - - - dm rootdg04 sdd - 17678493 - - - - dm mydg05 sde - 17678493 - - - - dm rootdg06 sdf - 17678493 - - - - dm rootdg07 sdg - 17678493 - - - - dm rootdg08 sdh - 17678493 - - - - v vol1 fsgen ENABLED 2048 - ACTIVE - - pl vol1-01 vol1 ENABLED 3591 - ACTIVE - - sd mydg01-01 vol1-01 ENABLED 3591 0 - - - pl vol1-02 vol1 ENABLED 3591 - ACTIVE - - sd mydg05-01 vol1-02 ENABLED 3591 0 - - -
