Stan,

I went through that several times in disaster recovery testing... finally
got it working.  What you need to do is edit your devconfig.lst file (if
you make several copies in different locations, make sure you edit the one
in the TSM server "bin" directory), and look for a line like this:

/* LIBRARYINVENTORY SCSI ATL DBR189 272 101*/

But, yours should have your library name and the serial number of your DB
Backup tape.
Update the number following the volser (272 in my example) to be the
element number of the slot in your library where the tape is loaded.
This should allow your restore command to find the tape.

You can get the element number from your library docs.  If in doubt, try to
figure out which slot corresponds to the lowest element and load the tape
there.  I know this all sounds pretty "hokey", but its actually documented
in the Admin Guide in the section about recovering the server with DRM, I
think.  And, I can testify that it works.

Good Luck,
Robin Sharpe
