EFMT3 and EEFMT3 support for ALTER VOLUMEENTRY

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

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

EFMT3 subparameter indicates READ/WRITE on an EFMT3 track device.
EEFMT3 subparameter indicates READ/WRITE on an EEFMT3 track device.
EFMT3 subparameter of RECORDING is only allowed with media types MEDIA5, MEDIA6, MEDIA7, MEDIA8, MEDIA9, or MEDIA10. The use of MEDIA1 through MEDIA4 will produce an IDC3266I error message being generated twice. Once for EFMT3 and once for the media type. The generation of the two IDC3226I error messages indicates an incompatibility between the EEFMT3 subparameter and the media type displayed.
