Who ever told you it is not possible for TSM to have access to two tape management systems is wrong. We have a Memorex ATL that uses 3490 carts with LMS as it's Tape Manager. We recently added a Magstar 3494 that uses 3590 carts with CA-1 as it's Tape Manager. We are an MVS/OS390 2.10 TSM server. Right now I have both defined in TSM, the archives go to the Memorex, while Backups(collocation shut-off) & Offsites go to the Magstar to take advantage of the bigger size tapes. You just define a new storage pool with a different device type, in my instance the archive device type is CARTRIDGE(old) while the Magstar is CART3590(new). I did have to 'move' data from the (old) Backups in the old ATL to the tapes in the new MAGSTAR and then the offsite copy just picked up that data as I moved it. When I did an Offsite copy each day I first copied the DISKPOOL, then NEWBACKCART, then OLDBACKCART until all the data was moved. When the data was all moved there was no longer a OLDBACKCART, I was able to delete the old OFFSITE as all the data from both ATL's was now in the new OFFSITE and I still leave the ARCHIVES in the old until I am ready to start bringing them over to the new. TSM has been great for managing these tapes during the change. You are welcome to email me if you would like specifics or have questions.
