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

See “Moving objects between disk groups” on page 257.

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.

See “Changing subdisk attributes” on page 279.
