In a word I think the answer is NO. In a modern DASD subsystem, you are using RAID of some sort at the device level. This means that any given data is spread across several physical disk volumes, unless a particular file is small enough to fit within one data block on the disk volume. But finding out where it is, and depending on the RAID setup, any other copies, would be impossible except possibly by scanning the physical disks for the data.
That's my opinion anyway.

For example userid ABC001 has minidisk 201. What is the serial number of the storage frame minidisk 201 resides? Ideally we would like to have this ability from zLinux (map linux device to storage frame serial) but would be happy if we could do so from CP. Need this capability on IBM, EMC, HDS storage.
