Yes and no.  Once a tape is ejected from the library, when it is reinserted,
it is anybody's game because it does not belong to a specific TSM server.
It is in FF00 status.  So, if you do a checkin command with a range,
search=yes, another TSM Server could get it.  This is why I do checkin
commands with a specific volume id when I checkin each tape.

At Share we have asked for a function to be added in general to setup an
include table for each TSM server.  This include table would limit what
ranges of tapes are allowed to be picked up by that TSM server instance.

Now, if the tapes are already in the library and assigned a scratch or
private category and the tapes can be stolen, that is a major problem that
support needs to know about.  I have never tried to see if I can cause one
TSM to steal tapes from another TSM server this way.

Subject: 3494 Volume Stealing


I just tested a problem brought to me by one of my clients.  They have one
3494 library shared by four TSM Servers.  Using 4.2.1 TSM, properly
configured with different 3494 Categories, it is possible for one TSM server
to steal a volume that is checked in to another TSM server.  This behavior
is not exhibited by 3.7.3.

Has anyone seem this?
