EFMT3

Data has been written to the volume in EFMT3 (enterprise format 3) recording format. A recording format of EFMT3 is valid with MEDIATYPE(MEDIA5, MEDIA6, MEDIA7, MEDIA8, MEDIA9, and MEDIA10) only.

EEFMT3

Data has been written to the volume in EEFMT3 (enterprise encrypted format 3) recording format. A recording format of EEFMT3 is valid with MEDIATYPE(MEDIA5, MEDIA6, MEDIA7, MEDIA8, MEDIA9, and MEDIA10) only.

To use the EFMT3 and the EEFMT3 recording technology, you must specify the MEDIATYPE(MEDIA5|ETC, MEDIA6|EWTC, MEDIA7|EETC, MEDIA8|EEWTC, MEDIA9|EXTC, or MEDIA10|EXWTC) operand of the CHANGEVOLUME TSO subcommand.
