Determining if DRL logging is active on a volume

To determine if DRL logging (configured using a version 20 DCO) is active on a mirrored volume

  1. Use the following vxprint commands to discover the name of the volume's DCO volume:

    # DCONAME='vxprint [-g diskgroup] -F%dco_name volume'
    # DCOVOL='vxprint [-g diskgroup] -F%parent_vol $DCONAME'
  2. Use the vxprint command on the DCO volume to find out if DRL logging is active:

    # vxprint [-g diskgroup] -F%drllogging $DCOVOL

    This command returns on if DRL logging is enabled.
