I would agree. We are using both J and K carts in the same library, same stgpool same devclass...etc. IBM installed the MES to the 3494 and the 3590 E1A's. We installed a newer version of drivers(atape 5.1.3.0, atldd 4.0.8.0) on AIX (4.3.3,TSM 3.7.3). Used TSM to label the new tapes and check them in. Everything is working. Per TSM (q vol) the most we have been able to put on a tape so far is a little over 81GB.

Woah, woah woah, I think you are talking 2 different things here. I believe the question being asked is "Can the single length 3590 tapes (denoted by a 'j' on them) co-exist in a library with the new extended length tapes (denoted by a 'k' on them)?" I believe that the answer is yes, as long as your tape drives are the 3590E drives. The 3590E tape drives will know the length of the tape when it mounts it (because of the little colored tabs below the label) and write it correctly. The 3590E writes out 256 tracks regardless of the tape length. I believe that the question you have answered is, "How do I go about upgrading my 3590B or 3590Ultra drives to the 3590E drives and use the same tapes?" In this case, there is a difference in the number of tracks it is writing and the procedure that is described below is valid. We have upgraded to the 3590E drives but have yet to put in any of the extended length tapes to test this theory, so I'm not 100% sure of this, but that is the way IBM has explained it to us.
