Skip the NOASSIGN stuff.
I guess I really was not clear, my apologies. The 4.4 and 5.2 are 2 different LPARs. 5.2 can only run in 64bit mode, and our 4.4 is 31bit, so 2nd level is out.

I don't believe it is possible for the DFSMS to mount a tape on a VTS drive without taking it. After the tape is mounted the drive gets attached to the requesting user. That was why I ran the mount in 4.4 first, and then just tried to use the drive as-is on 5.2 Thanks for all ideas! Keep them coming :-) Shimon
