The following command removes disks rootdg07 and rootdg08 from rootdg to

form a new disk group, mydg:

# vxdg -o expand split rootdg mydg rootdg07 rootdg08

By default, VxVM automatically recovers and starts the volumes following a disk

group split. If you have turned off the automatic recovery feature, volumes are

disabled after a split. 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 split shows the new disk group, mydg:

# vxprint

Disk group: rootdg
