Joni,
        In the past, I have always just run migration down to an empty disk
pool, removed the volumes from TSM and formatted new ones and added them to
TSM.  One note on that is that the MOD 9 must be 2 VSAM files.   It would
not let me allocate 1 file that covers a whole MOD 9.

Subject: DASD Volume on os/390- use VSAM extended?


Hello all MVS TSM users!

The TSM server is on os/390 2.10 and the DASD being used would be HDS MOD
9's.  Right now we have all of our disk storage pools on MOD 3's, but would
like to move it to MOD 9's.  Does anyone know if it is possible to use VSAM
extended which would allow the VSAM to be greater than 4GB?  Thanks!
