Volume formats

You can use DFSMSdss with the following DASD volume formats:

Volumes with indexed VTOCs, see Indexed VTOC for details.
Volumes with nonindexed VTOCs
OS/VS minivolumes in a VM environment
VM-formatted volumes (full or mini) with an OS-compatible VTOC beginning on track zero, record five.

All DASD volumes used by DFSMSdss must be initialized by Device Support Facilities (ICKDSF) and be mounted and online.

Note: You cannot use concurrent copy on minivolumes of any format unless they are on an RVA. However, you can use concurrent copy on full VM-format volumes that contain minivolumes to the extent that they are supported by IBM® Extended Facilities Product (IXFP) device reporting.
