Re: Creating Device Description

Got Jack's reply and haven't received the original yet.

If you are using a tape library then you may also get an additional tape 
device configured also.  On our system when I run
wrkcfgsts *dev tap*
I get
Description       Status 
TAPMLB02          VARIED ON 
TAPMLB04          VARIED ON 
TAPVRT01          VARIED ON 
TAP02             VARIED OFF
TAP03             VARIED OFF
TAP04             VARIED OFF

Under normal situations you do NOT use those devices.  They are reserved 
for very special occasions - for example, restoring your LIC and OS from 
tape before there's enough OS to know how to process a tape library.

Some tape devices can be configure in both "random" and "sequential" mode. 
 "Random" is the media library or "MLB".  "Sequential" is the "tradition" 
or non MLB.  Some tape devices, like the monster we have, won't allow you 
to configure it in sequential mode and won't recognize the 'TAP03' type 
stuff unless you are doing one of those restores of LIC and OS previously 
mentioned.

In SST you will see that they occupy the same position, but use different 
resource names.  Therefore only 1 can be varied on at a time.

If you are using BRMS, you want the Media Library (MLB) one.
