On behalf of Horst Sinram, IBM Boeblingen: I think there is a single misunderstanding. FBA devices always contain a single partition. They can NEITHER be formatted NOR partitioned. Formatting and partitioning is currently only supported for ECKD devices. This means that one has just to make a file-system on the partition and the device is ready for use (dasdfmt, fdasd, fdisk,.... don't work on FBA devices). You can also have a look into the Device Drivers book for more info on how to get a FBA device working.
