Use the LABEL procedure to run the EDGINERS utility so that you can process initialize, erase, and scan requests manually. With manual processing of EDGINERS, you can initialize and erase, or scan the labels of, any specific tape volume, whether it is already defined to DFSMSrmm or not. Once you initialize a volume, it is defined to DFSMSrmm.

The LABEL procedure is supplied as EDGLABEL in the DFSMSrmm SAMPLIB data set. You must have a tape drive on which you can initialize tape volumes.

Tapes can also be relabeled by defining new resource profiles in the FACILITY class. If the user has access to the security resource, DFSMSrmm allows the tape volume VOL1 label to be created or destroyed at time of use, regardless of the status of the volume.

The tape label version for ISO/ANSI version tape labels can be specified in the EDGINERS EXEC JCL. If no tape label is specified, DFSMSrmm uses the version number in the parmlib DEVSUPxx member as the default tape label version when initializing ISO/ANSI tapes. See z/OS DFSMSrmm Implementation and Customization Guide for more information on labeling tapes using the EDGINERS utility or by defining resource profiles.
