DFSMShsm can only dump and recover from dump those Linux volumes that are formatted with dasdfmt and partitioned with fdasd. All other DFSMShsm functions are unsupported for Linux volumes. No data sets should be migrated off or recalled to Linux volumes. Backup is not supported for Linux volumes or partitions. Use Linux volumes only as PRIMARY volumes and use them with the NOAUTOBACKUP, NOAUTOMIGRATION, and NOAUTORECALL options. For the dump class that you use with Linux, use the option VTOCCOPIES(0). VTOCCOPIES is not supported for Linux volumes.
