Hi listmembers

Put me on the "me too!!" list. I do the "sfind" every time a tape gets in 
trouble and rearchiving has to be done. We are in the process of using SSD for 
the mm luns but still, the information should be in the samfsdump (which we do 
three times a day).

Yes!!

An easy example: a tape breaks/goes bad/becomes unreadable. It is only one
copy of two (or more).  You want to rearchive all the archive copies on
that tape, so you need to find out what files are on it.  At the moment,
the only way to do this is an archive_audit of all filesystems that
might have had archive copies on the tape or an sfind </FS> -vsn <VSN>
of all the filesystems that might have had archive copies on that tape.
Both are metadata intensive operations and can be slow.  But I'm
already doing a metadata intensive operation every night: samfsdump.
If I can just pull the file/VSN information out of the dump output(s),
I can save myself another trip through the (live) metadata.

I've wanted this capability almost since the day I started using SAM.
