PROBLEM: (89300, BCGM70HRD) (PATCH ID: OSF520-165)
********
This patch corrects the problem with a mirrored LSM volume with dirty
region logging (DRL) enabled still doing a full resynchronization
during a recovery after an unclean shutdown.
This full resynchronization will only occur the first time and then DRL
will be properly enabled.  To determine if any current volumes will need
to have the DRL replaced to avoid this, execute the following command:

volprint -v -a

Check the field recover_checkpoint.  If this field is 0, then a
new DRL for the volume will need to be done if you wish to avoid this
full resynchronization.  NOTE:  Ignore RAID5 volumes
as this problem doesn't apply to them.

Example of creating a new DRL for the volume after the patch is applied
is:

# volplex -o force dis vol01-03
# voledit -r rm vol01-03
# volassist addlog vol01 dsk6
# volprint -av
 
The volume will now have the recover_checkpoint enabled.
