Determining if DRL is enabled on a volume

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

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

   # DCONAME='vxprint [-g diskgroup] -F%dco_name volume'

2. To determine if DRL is enabled on the volume, use the following command with the volume's DCO:

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

   DRL is enabled if this command displays on.

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

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

   Sequential DRL is enabled if this command displays on.

   Alternatively, you can use this 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.

   See "Determining if DRL logging is active on a volume" on page 272.
