Sorry for the delay in responding. My old PC was disposed of and I got a new one. I don't know that they use CPFORMAT to format the DASD before telling me it's available. Should they? Anyway. I found this excerpt from the DFSMSdss Storage Administration Guide, from the chapter on Linux Dump and Restore. The disk label, VOL1, indicates that a z/OS system can process this volume Mine all have VOL1 as their Disk Label, so I guess I'm still confused.

Because for mini-disks, the z/VM systems programmer does not allocate cylinder 0 to the Linux guest. So, when Linux writes the VTOC on what it thinks is cylinder 0, it is really writing it somewhere else. > How can I get it on the Z/OS side for the mini-disks? It should have been created by z/VM when it was CP formatted by the z/VM systems programmer. If it was not, they need to look at how they're initializing the volumes.
