If it contains the user directory, it should have a minimal VTOC. An ICKDSF FORMAT CPVOL (or simply a CPFMTXA) should place a 2 or 3 record VTOC immediately following the volume label (which is at cyl 0, track 0, record 3). Can you do a DDR TYPE or PRINT of that track to see what is really there?

My normal backup procedure for right now is to vary the DASD online to z/OS, then use FDR/Instant to snapshot them and back them up. I have created a new guest and loaded RHEL onto it. I can back up all of the volumes except for one; the snapshot for that one fails with a message "I/O ERROR READING THE VTOC." No snapshot means no backup. This volume is part of a volume group that contains the /usr directory. Is there a way I could recreate a VTOC on this volume without having to redo the logical volume? Thanks, Jon
