On OS/390 it depends on the tape management system. If you're running
DFSMSrmm, then just specify the REJECT ANYUSE(...) for the volser 'range'
that is non-OS/390 in your EDGRMMxx parmlib member. If you are using any of
the CA alternatives (TLMS, CA-1) then you will have to modify the sample
CBRUXENT OAM user exit to reject any non-OS/390 volsers. Make sure that this
exit is running on ALL systems/LPARS that share the 3494 library. The 3494
will notify each system/LPAR that is up and running. The exit may be on 2
out of 3, but that 3rd system could still accept the non-OS/390 tapes.
Speaking from experience on that one!

On the TSM server, we have a server script file that runs the checkin libv
command with the volrange option for only those TSM tape volsers.

As for OS/400....last time I looked there was no tape management support
available. Maybe OEM software venders..?

We share a 3494 between OS/390 and an AIX TSM server. Since moving to
DFSMSrmm, we haven't had a single occurance of the systems accepting the
others' tapes.
