IEHINITT can be used to write BCDIC labels on 7-track tape volumes and EBCDIC or ASCII (ISO/ANSI format) labels on 9, 18, 36, 128, and 256 track volumes. Any number of tape cartridges or tape volumes can be labeled in a single execution of IEHINITT.

IEHINITT is supported in all IBM 3494 and 3495 Automated Tape Library Dataserver environments, as well as the 3495-M10 environment. Special considerations apply when using IEHINITT in the 3494 or 3495 Automated Tape Library Dataserver.

Multiple tape volumes initialized via a single INITT command are labeled in sequential order by specifying a serial number to be written on the first tape volume. The serial number must be specified as six numeric characters, and is incremented by 1 for each successive tape volume. If only one tape volume is to be labeled, the specified serial number can be either numeric or alphanumeric.

You must supply all tapes to be labeled, and must include with each job request explicit instructions to the operator about where each tape is to be mounted.

IEHINITT writes 7-track tape labels in even parity (translator on, converter off).

Previously labeled tapes can be overwritten with new labels regardless of expiration date and security protection. SAF/RACF is invoked to determine the proper level of access to a tape volume for drives in a Tape Library Dataserver.

If errors are encountered while attempting to label a tape, the tape is left unlabeled. IEHINITT tries to label any tapes remaining to be processed.
