Determining if DRL is enabled on a volume

To determine if DRL (configured using a version 20 DCO) is enabled on a volume

  1. Use the vxprint command on the volume to discover the name of its DCO. Enter the following:

    # DCONAME='vxprint [-g diskgroup] -F%dco_name volume'
  2. To determine if DRL is enabled on the volume, enter the following command with the volume's DCO:

    # vxprint [-g diskgroup] -F%drl $DCONAME

    If this command displays on, DRL is enabled.

  3. If DRL is enabled, enter the following command with the DCO to determine if sequential DRL is enabled:

    # vxprint [-g diskgroup] -F%sequentialdrl $DCONAME

    If this command displays on, sequential DRL is enabled.

    You can also use the following command with the volume:

    # vxprint [-g diskgroup] -F%log_type volume

    This displays the logging type as REGION for DRL, DRLSEQ for sequential DRL, or NONE if DRL is not enabled.

    If the number of active mirrors in the volume is less than 2, DRL logging is not performed even if DRL is enabled on the volume.
