To determine if DRL logging (configured using a version 20 DCO) is active on a mirrored volume
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'
Use the vxprint command on the DCO volume to find out if DRL logging is active:
# vxprint [-g diskgroup] -F%drllogging $DCOVOL
