I am confused by your comments below - I am now at 2.1.0.7 of my MVS server,
and I am also setting up a disaster recovery copypool.  I did a DEFINE
DEVCLASS and set the highlevel qualifier to ADSM.BK.  Needless to say, it
seems to be working - I am getting tapes created with the name of ADSM.BK.BFS.

I would also note that While the tapes seem to be ok, two of the tapes are
marked in TMS as having abended - but I did not see any abend.  I did have
cause to cancel one process as it was at reel change time - it was looking for
a econd tape drive, and my test system only had one available.  I would not
have expected this to mark the tape as abended, though.  I did have a
situation where the tapes were run on a back level server (level 3 or 4, not
sure which) due to an unusual testing request from the security dept.  But
that's another story....

A PTF has enabled the use of multiple qualifiers in the PREFIX setting of
the devclass... with one caveat: you are still limited to a maximum of 8
characters in the prefix field, including the dots. Thus you can define a
devclass with a prefix like ADSM.OFF, ADSM.LOC, ADSM.A.B, etc. But you can't
have a prefix of ADSM.OFFSITE or ADSM.LOCAL because these exceed 8 characters.

The latest PTF level for MVS is V2 R1 L0.9. The PTF numbers are UN91696,
UN91697, UN91698, UN91699, and UN91700.
