Even though access SAN attached devices like and tape and disk
simultaneously through a single HBA is supported, my experience has been
that both will work just fine most of the time, but you may experience
mysterious errors with the tape devices. The most common issue was SCSI
resets in the middle of a backup which would drive Networker crazy. In
our case we were accessing the tape devices through a bridge, so, it
could have been issues with the bridge. Since we couldn't figure out
what was causing the issues, we isolated the tape device on to its own
HBA, we have had no issues since then.

All this was happening about 2 years ago, technology may have gotten
better since then.

Subject: [Networker] use of one fibre card for disk and tape access

What is the general opinion for use of one fibre card to access SAN
attached disk and then also using that fibre card for access to SAN
attached tape devices. I know that such configurations are supported but
do they work consistently and are they recommended?
   
  Thanks.
