Help!  I am feeling quite dumb here, have searched the archives and read
the manuals all to no avail.  It's probably just me ...

I have an IBM LTO 3583 library.  I have successfully inserted tapes and
begun backing up with TSM.  All
was going well.   Recently I decided that it was time to use the library as
it was intended.  Using DRM I
decided I should remove COPY tapes and DB Backup Tapes etc.  and keep them
in my "vault".   That was
easy.  Now however I would like to put back in some of the tapes that have
expired.  Here is where I am
having trouble.

We have one column in the library to hold tapes and one I/O port.  I can
add new scratch tapes with label
libvolume ... checkin=scratch ..    but I can not seem to get those old
used and expired tapes back in.

I have tried the   checking libvolume xxxxx scratch=yes.  I am prompted
(through the actlog) to insert the tape in slot 16.  Here is my problem.
Which slot is 16?  I have tried a couple of different ones and get

ANR8306I 007: Insert LTO volume 111ACH R/W into the slot
                         with element number 16 of library LTOLIB within 58

                         ready. </mv>

I do not know how to tell what slot is 16.   Help!  Pretty soon I will run
out of new tapes to add and I can't get the old ones back in.  I feel
foolish.  It seems like this should be easy.  Help!   And will we're at it,
how can I log on an admin client (in line mode) with mount messages being
sent to this session.

Thanks in advance for any and all help, including RTFM -  just tell me what
page number!
