--> "Excl Filespace /mnt/stats"

So the filesystem is really excluded. If you run backups through "dsmc
incr" or schedule it should not be sent. As far as I understand you are
concerned the filesystem still shows up in GUI, right.

--> "Here is a bit more info.
TSM Server 4.2.2.12 running on Solaris 2.7
TSM Client 3.7.2.0 running on Solaris 2.6"

The client is rather old (just after I was born :-)
Have you tried with *any* newer version client? Solaris 2.6 is supported
even in v5.1 so you have a wide choice of v4.1.x, v4.2.y & v5.1.z
I would say this is GUI client bug which you could report in 1999 but not
now. Sounds like I worked too much with IBM and started express myself as
an IBMer :-)
