ALTER VOLUMEENTRY

Use the AMS ALTER VOLUMEENTRY command to modify the attributes for an existing tape volume entry.

Enterprise format 4 (EFMT4) and enterprise encrypted format 4 (EEFMT4) are new recording technologies used by the TS1140 tape drive. EFMT4 is the non-encrypted recording format and is the default recording format for the TS1140. EEFMT4 is used to specify that the data on the tape is recorded in the encryption format.

The ALTER VOLUMEENTRY command allows recording fields in the volume records of a tape library to be altered with the following rules:

EFMT4 subparameter indicates READ/WRITE on an EFMT4 track device.
EEFMT4 subparameter indicates READ/WRITE on an EEFMT4 track device.
EFMT4 subparameter of RECORDING is only allowed with media types MEDIA9, MEDIA10, MEDIA11, MEDIA12, or MEDIA13. The use of MEDIA1 through MEDIA8 will produce an IDC3226I error message being generated twice, once for EFMT4 and once for the media type. The generation of the two IDC3226I error messages indicates an incompatibility between the EFMT4 subparameter and the media type displayed.
