Anthony,

Wanting to make sure what you are asking.  Do you mean that you have two LPARs 
which share the same VTS hardware; however, don't share the TMC?  If your 
answer is yes, then are you also asking about making sure that LPAR1 does not 
insert tapes from LPAR2 and vice versa?

If there are correct, then let me know.  Using DEVSUP and minor exit changes to 
the CA-1 exits can take care of this without any issues.  Currently running 
that way today with a TS7740 and I have 5 separate TMCs using the save 
hardware, different volumes, different DEVSUP and minor USERMOD changes to 
prevent he LPAR from picking up the wrong tapes.




Thanks,

Craig

Anthony,

All CBRUXENT does for CA-1 is convert the 8-character library name to ROBTYP 
and ROBID.  It's pretty straightforward.  DEVSUPxx should make no difference.
