In this example, there are fewer DCO plexes than data plexes.

# vxprint -g PRODdg

Add a DCO plex to the DCO volume using the vxassist mirror command:

# vxsnap -g PRODdg addmir data_vol_dcl alloc=PRODdg02

Associate the data plex with the new DCO plex and convert it to a SNAPDONE state:

# vxplex -g PRODdg -o dcoplex=data_vol_dcl-02 convert

state=SNAPDONE -V data_vol-04

# vxprint -g PRODdg
