Re: Desperation, DR, and four TS3100 libraries...
Wanda, Yes, the Web interface would work, you would just have to pay attention to which screen you were on, since all four would look alike. I think it is a lot of key clicks for each tape mount, too, since the Web interface isn't meant to be a regular operator's interface, and doesn't have speed or ease-of-use in mind.

Re: Desperation, DR, and four TS3100 libraries...
Here are my thoughts: Since this is a DR instance, all TSM data should be read-only. With that said, you can restore the production TSM instance four times, so that you'll essentially have 4 identical TSM instances running. Each TSM instance should have its own tape library. Mark all copy volumes readonly or unavailable to start off with. To determine which tapes should go where, you can run off of one instance and run volumeusage or content selects for specific DR nodes. That'll get you a tape list and you can more accurately load/checkin tapes to balance the restores across all 4 instances. Since these tapes probably aren't collocated, there will inevitably be some tape swapping between libraries, but at least you'll be able to run restores off of 4 drives and you'll minimize the number of tape swaps you'll need to do (if you balanced correctly). Invariably, you'll be doing some amount of tape swaps, so maybe your just better off running the one instance with manual drives. Oh well, I tried.

Re: Desperation, DR, and four TS3100 libraries...
Wanda, This is Tom Wright from Gresham and Nick is correct. Our Clareti Storage Director can manage the 4 small libraries off of the back-end and present one virtual TS3500 (3584) to TSM. That would solve your problem but would require our product to be in the mix. If that is of interest or if you would like more information please let me know.

Re: Desperation, DR, and four TS3100 libraries...
Wanda, My solution isn't much better, but here goes: 1) Like you said, define 1 manual library, 1 device class, with 4 LTO4 drives, and get them all working and defined to the DR environment. 2) You will be using the IBM drives, of course, so I am presuming the IBM drivers will be installed by you or your DR vendor. 3) Start a TSM administrator window in -console mode, so you can see the tape mount requests. 4) When your tape operator sees a tape mount request, he puts the appropriate tape in the I/O door belonging to that tape drive's library. 5) You didn't say if you were Unix, Linux, or Windows. I will explain it as if it is AIX, and you can transpose. From a Unix shell window, your tape operator uses tapeutil, the linemode library manager that comes with the IBM drivers, to do the tape mounts for you. He can issue the commands to move the tape from the element number of the I/O door straight to the tape drive. 6) When he sees an unmount request, he issues the tapeutil command to move the tape from the drive to the I/O door, and puts the tape back in the stack. If it were me tackling this one, I would write two short ksh scripts called "tape_mount" and "tape_unmount" where the tape operator just puts in which tape volser he is mounting, and which drive it should go in, and let the ksh scripts translate that into the actual device name, and tapeutil syntax, so there would be fewer mistakes. Also if it were me, I would build this experimentally using a tape library or libraries and drives while still back home, so I could build the script and debug it, then bring it with me to the DR exercise, and all I would have to change would be the /dev/smcX and /dev/rmtX device names, and start mounting tapes. Do you see any fatal flaws in this? It is a lot like your original idea, but typing the mounts and unmounts on the faceplate of four different TS3100's would drive me buggy. Hopefully this would be less tedious. Best Regards, John D.
