John is almost right, but you will only need one manual library. Once a tape is SMS managed, he can tell the difference between the different tape technologies. I have done exactly what you are doing. If you want to talk offline, I'll be happy to help. Scott Rowe

Now, if you're using an ATL, then make one library for the old drives and another library for the new drives. If the new drives are not in a library, then create a new library (and storage group) for the new drives. Change the IODF to say that the TS1120s are in a "Manual Tape Library" (MTL) and simply make up a LIBRARY-ID and LIBPORT-ID which doesn't conflict with anything else in the IODF. Also create a new storage class. In the storage class ACS routine, look for UNIT=TS1120 and assign the new storage class to the allocation. In the storage group ACS routine, look for the new storage class and assign it to a new storage group. Use ISMF to create a tape library with the LIBRARY-ID and associate it with the new storage group. Now, when z/OS detects that the volume serial to be mounted is defined in OAM as being in the MTL, it will ask that the volume be mounted on one of the drives assigned to the MTL (one of the new drives). I cannot think of any other way to do this. -- John ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html CONFIDENTIALITY/EMAIL NOTICE: The material in this transmission contains confidential and privileged information intended only for the addressee.
