George,
I was playing around a bit with this in the NMC GUI and found if you go to
"Media" and select "Save Sets" you can set a query for the save sets you are
interested in. Then in the "Save Set List" tab it gives you a list of all of
the volumes that save set is on.
For instance a save set from my weekend full backup displays in the volume name
column:
150021(1000.0,h),150022(1000.0,m),150023(1000.0,m),150024(1000.0,t)
That's the sort of information you're looking for, right?

I agree, but in this case, there's so many top level directories for
some of these save sets that it could take me an unacceptably long time.
Would the following scenario possibly work???:
Obviously, I can run 'mminfo' and have it tell me the size (sumsize) of
each piece of the save set that's on each volume. Let's say there's four
pieces, and I specify something like 'sumsize(20)' to have it list it
out in actual bytes. So what if I then run 'nsrinfo -s server -t
nsavetime -v client' for the given save set and capture that to an
output file. That will list all the pieces/parts in the save set, file
by file, with the 'NSR size' and 'file size' of each. Next, I write a
script to parse that output file and add up the sizes until it hits
something close to the 'sumsize(20)' for the first volume. Once it hits
that, it then prints out the pathname of that file. I then manually
check to see if that directory spans. If not, it's probably one of the
directories just before or after that? I could then do this for the
second piece and third piece. In this example, the fourth piece would be
the last so that would be moot.
Assuming this harebrained scheme would even work, I'm not sure what the
difference between 'NSR size' and 'file size' is, but 'NSR size' is
always a little bigger. Maybe I would want to use 'NSR size' for this?
Also, is the order that 'nsrinfo' lists everything in the same as the
order that the data was actually backed up? If not, this goofy method
won't work.
Maybe there's a better way (sigh ...).
