I have seen such problems couple of times in our environment. In our
case it was always a mismatch of duplex setting on network switch port
and TSM client m/c port. I forced both i.e. Network Switch port and TSM
Client m/c port to Full Duplex (of course speed setting is also same),
this resolved our problem. 

This problem is observed if port is set to Auto negotiate.

sometimes a little bit of data is sent to tape, but invariably
communication with the server gets hosed and I start seeing the
following messages in the client's error log:

on this particular issue, and it looks like some folks were able to
resolve similar problems by reinstalling the client's software ... which
I've tried to no avail.  I've talked to IBM, and they were zero help.
I've talked with Sun to verify that the interface on this Solaris box is
set up correctly (which I knew it was already).  I've checked the
settings on the switch port this client plugs into.  I've even pulled a
new fiber cable from the client to the switch.

It's very strange, too, because this Solaris server is clustered, and
it's sister server (which is set up exactly the same way) has no
problems.  Everything in the dsm.sys and dsm.opt files of these two
clients is exactly the same.
