You only need to do this stuff at config time, you won't need the web interface
on a day to day basis, any more than with the 3494.
(although it is surely nice to have just to check on what's happening in there).
You can also forego the web interface and use the library panel for the
definitions, but THAT is indeed a pain.
And there is a CLI, but I've never used it; and that's the same IP connection,
so I don't think that would help you.

As always, thanks Wanda. That clears up / confirms a lot of what I was
thinking. Don't know about the I/O path failover for these SAN paths - need to
ask my OS guy.
Having to do everything from the "web interface" is going to be a really pain
if not a security concern/issue. Currently, the 3494 is on the same private
subnet as all servers and nodes that perform backups - isolated/locked-down.
Never used it for anything more than LM functionality from the Linux TSM
servers - no GUI, no web, just CLI. I wonder if you can define more than one
IP connection?
