1.1.5 Media types
The media type specifies the type of physical media of the volumes defined to
DFSMSrmm.
DFSMSrmm uses the volume’s media type as defined to DFSMSrmm when
requesting manual cartridge entry; you must ensure that DFSMSrmm has the
correct media type to avoid allocation and mount problems when the volumes are
later used. You use the RMM ADDVOLUME or CHANGEVOLUME
subcommands with the MEDIATYPE operand to set the media type.
Figure 1-13 shows the different media types and the terms used in SMS and
DFSMSrmm.
