We do this.

Our current configuration is TSM on ZOS and TSM on AIX sharing the same
3494.  Neither side really sees the other side. The tapes and drives used
by the TSM AIX server are not accessible or seen by the TSM ZOS server.

TSM ZOS uses 3590-B (10GB) drives/tapes attached via SCSI/ESCON
"converter" boxes (i.e. A60/A10).

TSM AIX uses FC attached 3590-E (20GB) drives.

The best docs for this kinda processing are on the IBM REDBOOKS site,
http://WWW.REDBOOKS.IBM.COM and then put 3494 in the SEARCH field. The
main book for this topic is a little aged but still works: Guide to Sharing and 
Partitioning IBM Tape Library Dataservers

        Subject:        Sharing 3494 library between TSM and VM/ESA


Hi everybody,

I'm asking this for a collegue therefore I'm a bit vague ...

Does anyone share a 3494 library between the open world (W2K or UNIX
with TSM) and a mainframe (VM/ESA)?
If this is technically possible what kind of hardware (3590 controller
...), software or organisational tasks (tape ranges ...)
is required?
Is there any kind of documentation available on the net?

Thanks in advance for any information!

Kind regards and greetings from Austria
