The problem may have originated with the VTOC IBM shipped on cyl 0 of the VM5.1 System DDR of 510RES. It says 3340 cyls. CP doesn't care, it knows the pack is 3339 cyls.
You CMS ACCESS-ed the device and CMS's Q DISK reported that the VTOC says the size is 3340 cyls. This 510RES VTOC bit me when our MVS folks ran a MVS tool to migrate our VM dasd to a DS8000 storage box; their dasd migration tool compared the VTOC size info against the actual pack size and quit if they didn't match. All of our VM5.1 systems had this VTOC discrepancy on 510RES and the tool wouldn't migrate them until I fixed cyl 0. Anyway, as Dave Kreuter pointed out, when you re-formatted cyl 0 you trashed the active-directory pointer. Hopefully you're in a position to run DIRECTXA with the source directory file and update that cyl 0 pointer. -------------------------------------------------------- This e-mail, including any attachments, may be confidential, privileged or otherwise legally protected.

The zVM 5.1 res volume is on a 3390 mod 3 pack. This volume should be 3339 cylinders. It is on DASD carved from a DS6800 as 3339 cylinders. When I attach this volume and access it, I get the following: LABEL VDEV M STAT CYL TYPE BLKSZ FILES BLKS USED-(%) BLKS LEFT BLK TOTAL 510RES 001 Z R/W 3340 3390 OS I have tried the following: DDR to a new volume CPFMTXA FORMAT cylinder 0 CPFMTXA ALLOCATE system areas DRCT 1-20 PARM 21-38 PARM 39-128 PARM 129-188 SALIPL for the IPL data When this new volume (same name) is IPLed it says the directory is invalid... Any ideas as to what I should try next to get the res volume to see itself as a 3339 cylinder volume? Thank you. Cecelia Dusha
