That brings up a question. I know if the past, we were told not
to mix DISK and TAPE resources on the same FC HBA, but is that
suggestion still valid? 
        Will it not work at all? Or will it work but extremely poorly
because of the different types of data flows? 

        Just curious if something has changed in the last few years of
FC architecture that makes this rule-of-thumb no longer apply...

Thanks. I have 3 clients to put on LAN FREE backup, but 2 of them cannot
have more than 2 HBA's, what route should I go? And these 2 HBA's is
needed for disk for redundancy.

Yes, you need to zone tape drives to the machine running Storage
Manager.
Multiple tape drives can use the same HBA.

Tape and Disk cannot coincide on the same HBA. You need a separate
adapters for disk and tape. This stems from the days of S360 (and
earlier?) where there were seperate channels for streaming channels
(tape) and block channels (disk). Guess this dates me...

I am trying to implement a LAN FREE backup, and my question on the
Storage Agent/Client, do I need to create a zone from one of my HBA to
the Fiber Channel Tape drives? And if I can share the HBA with disk and
tape?

Any help is greatly appreciated.

Thanks,
Rubie
