I am not familiar with Flashcopy, so I have not made any posts on this
thread.

However, from a design viewpoint, here is what you might consider.

When you are ready to cut to production, snap a copy or backup of all the
volumes including the ICF catalog.  Perform your conversion and if all goes
well then you have no need of the copy you made.  If for any reason you need
to start over, turn the copy job around and copy the backup volumes to the
production volumes.  This will overlay all the work you have done, put
things back to where they were when you started and all your catalog issues
will be solved.  Try to implement in production again.  If you still have
failures, you always have the beginning point to fall back on.

The main drawback I see to this is that it will take more time to copy the
backup data and overlay the production volumes than simply varying devices
offline and online.  However, you never touch the backup volumes, except to
read them in during a restore operation to get back to where you started.  I
do not know if the Shark supports this or not, but at EMC these backup
volumes could be used as input to the restore operation without ever
bringing them online to the host.

I hope I have actually understood your plans and desires.  From a DB2
perspective, you should have no problems with the procedure you have
outlined assuming that you include all the volumes that are touched by DB2.
This would include the BSDS data sets, the active logs and archive logs if
they are on disk, the DB2 catalog, the ICF catalog and the application data.

I hope this has helped, fell free to call or e-mail anytime.
