We use CPFMTXA to format our 3390 dasd first under VM. This places a vtoc on it that our z/OS system can then see and FDR can use. I've seen the term "dummy vtoc" used. Then for linux we format the dasd with dasdfmt. We use minidisks on a volume so there are usually several mini disks for linux on a 3390 volume. We must do the CPFMTXA or FDR on z/OS will NOT do the backup correctly.

We are finally getting rolling on our Zlinux project under z/VM. It is our understanding that formating a 3390-3 with dasdfmt -d cdl should allow us to then backup this volume with FDR. That's what the man pages say and I heard it at Share. We tried it and the FDR is falling with a user abend U888 complaining about the vtoc. I used the following to format: dasdfmt -b 4096 -d cdl -f /dev/dasdk -l LNX009 -p -y What have I missed?
