Disabling and re-enabling DRL

 To disable DRL (configured using a version 20 DCO volume) on a volume

# vxvol [-g diskgroup] set drl=off volume

To re-enable DRL on a volume, enter this command:

# vxvol [-g diskgroup] set drl=on volume

To re-enable sequential DRL on a volume, enter:

# vxvol [-g diskgroup] set drl=sequential volume

You can use these commands to change the DRL policy on a volume by first disabling and then re-enabling DRL as required. DRL is automatically disabled if a data change map (DCM, used with Veritas Volume Replicator) is attached to a volume.
