That's probably the problem. VM was never taught how to deal with indexed volumes. If you're sharing disks between OS/390 and VM, you should initialize them with DSF CPVOL FORMAT on the VM side (to make sure that OS/390 is told that a) the volume is full and it shouldn't try to allocate anything there, and b) that it's not a indexed volume). > I was able to successfully do this with a volume that was DEDICATED to a > LINUX GUEST.. > but not this MDISK situation. With dedicated volumes, the Linux system is dealing with real cyl 0, so it was able to correctly set up the VTOC as a non-indexed volume. > I'm a VM newbie...so I guess I know I'm doing something wrong here... > WHAT STEPS DID I MISS or DO WRONG? Also make sure that the volumes are marked shared in SYSTEM CONFIG, in the IOCP, and in the OS/390 config.
