Zoltan, I went through this a couple of years ago. I still have my notes on what I did, but I wouldn't promise that they're 100% complete (or even represent the most sensible way to do this!). The general procedure was:
0) Prevent tape activity in all servers (mountl=0 everywhere, drives offline in lib mgr servers) 1) check out the tapes from the existing lib mgr server in groups, each group being comprised of the tapes that belong to one of the lib mgr client TSMs; keep these groups of tapes physically separate while they're not in the library (don't mix the tapes up!) 2) check out the scratch tapes, keeping them in a separate group 3) change ownership of the library: delete the paths/drives/library from the old lib mgr server, define in the new one; then in the lib mgr clients, define the new lib mgr TSM server (could be done ahead of time) and update the 'primarylibmanager' parm(s) 4) check in the groups of tapes in the new lib mgr server, specifying status=private and owner=xxxx for those tapes that belong to lib mgr client TSMs and specifying status=scratch for the scratch tapes. To accomplish #1, I used a series of select statements in the old lib mgr server: select 'checkout libv autolib1 '||volume_name||' remove=bulk checklabel=no' from libvolumes where owner='TSM1' select 'checkout libv autolib1 '||volume_name||' remove=bulk checklabel=no' from libvolumes where owner='TSM2' The select for #2 : select 'checkout libv autolib1 '||volume_name||' remove=bulk checklabel=no' from libvolumes where status='Scratch' Piped the output of these selects into files. I then broke the resulting checkout statements into groups of 10 because I had an I/O station with a capacity of 10 (probably not necessary...won't TSM just yell every minute until you free up space in the I/O station?). Ran the checkouts and put the tapes on the shelf/counter/whatever temporarily, making sure to keep the groups separate. The checkins for #4 above: checkin libvolume autolib1 search=bulk vollist=x status=private checklabel=barcode owner=tsm1 Run repeatedly for each batch of 10 tapes for each tape-owning TSM lib mgr client in turn. This is why you've gotta keep those tapes segregated; you're going to be assigning ownership in the new lib mgr server strictly by which tapes you insert into the I/O station during these checkins. (I don't remember why I needed the 'vollist=x' parm, but I assume it was necessary...in any case, things may have changed since that time) Finally, the scratch tapes get checked in: checkin libvolume autolib1 search=bulk vollist=x status=scratch checklabel=barcode ...again in batches of 10. If you're actually throwing away the old lib mgr servers, then I think this about covers it; if you're going to continue to use them as lib mgr clients, then there's some volume history cleanup (of type=remote entries) that'll need to be done in them. I don't have in my notes that an audit lib was necessary in the lib mgr client TSMs after all this; I think that if you get the tape checkouts/checkins correct, then it's not needed (and if you don't get them correct then you've got some problems!), but I suppose it wouldn't hurt to do one anyway, just to be sure.

Unfortunately, the tape library owners/managers are these two AIX boxes. Has anyone here gone through changing which TSM server owns a tape library, that can offer some hints, tips, suggestions ? How did you accomplish this? What steps did you take ahead of time?
