But what about a real disaster?  Would you need to write 3592 tapes?  I would 
think so, and in that case you should certainly have it worked out (and tested) 
now, not wait until the real thing

Hello [email protected] !

I talked with my SMS guy.

It turns out that we have never written to 3590-1 tapes during our DR 
exercise.  We read from them to restore the system with separately 
defined non-library drives, but never write, so our SMS routines do not
come into play. (We do a little writing to 3490 tapes.)

As a result of this discussion this will be on our agenda for the next 
DR exercise.

Here is part of the code in our current SMS definition.


FILTLIST LIB_TAPE    INCLUDE('3590-1') /*Library Tape */

WHEN (&UNIT EQ &LIB_TAPE          /*  3590 TAPE */
  AND &STORCLAS = 'SCLIBDUP')      /*  Tape Library SC */
   DO
     EXIT /* Exit with STORCLAS=SCLIBDUP*/
   END
                                          /*  */
WHEN (&UNIT EQ &LIB_TAPE)              /*  3590 TAPE */
   DO
     SET &STORCLAS = 'SCLIBDUP' /*Force SCLIBDUP */
     EXIT
   END

The initial thought from our SMS guy was to disable the allocation of 
3590-1 to the ATL at the DR site.

We will be talking about this over the next week or so and we will 
definitely be writing to 3590-1 tapes at our next exercise.

Thanks to all who contributed to this discussion.
