Joining disk groups

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

Note:

You cannot specify rootdg as the source disk group for a join operation.

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 Symantec products. The TUTIL0 values are temporary; they are not maintained on reboot. The PUTIL0 values are persistent; they are maintained on reboot.

# vxprint

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
