Reattach any snapshot volume back to the primary volume to be upgraded:

# vxsnap -g PRODdg snapback SNAP-data_vol

Turn off FastResync on the volume to be upgraded:

# vxvol -g PRODdg set fastresync=off data_vol

Disassociate and remove any older DCO object and DCO volumes:

# vxassist -g PRODdg remove log data_vol logtype=dco

Upgrade the volume by associating a new DCO object and DCO volume:

# vxsnap -g PRODdg prepare data_vol alloc="PRODdg01 PRODdg02"

View the existing DCO plexes and plex state.

In this example, there are enough DCO plexes for the data plexes. Also, no data

plex is associated with a DCO plex.

# vxprint -g PRODdg

Convert the data plex state from SNAPDONE to ACTIVE:

# vxplex -g PRODdg convert state=ACTIVE data_vol-04

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

state:

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

state=SNAPDONE data_vol-04

# vxprint -g PRODdg
