Tape Library Dataserver Considerations

To run IEHINITT in a library dataserver environment you would use JCL similar to:

//anyname   DD  UNIT=(,,DEFER),
//              VOLUME=SER=volser,
//              DISP=(OLD,KEEP)

'anyname' is the name on the INITT utility control statement.

'volser' is the volume serial number of a volume which meets all of the following requirements:

The volume resides in the tape library containing the volumes to be initialized.
The volume has the PRIVATE use attribute.
The volume is recorded in the tape recording technology - either 18, 36, 128, or 256-track - that is to be used in labeling the tapes.
The volume does not have the read compatible special attribute.
The volume is NOT one of those that will be labeled.

Note: No unit name is required, provided that 'volser' is a library-resident volume.

Additional considerations for running IEHINITT in an Automated Tape Library Dataserver are:

IEHINITT is not cognizant of library categories and will mount and initialize tapes in a Tape Library Dataserver without regard to whether they reside in a SCRATCH or PRIVATE category.
Message IEC701D, the normal WTOR permission message issued to the tape/operator's console does not appear on the console when processing on drives in an Automated Tape Dataserver.
