IEHINITT utility
IEHINITT is a system utility used to place standard volume label sets onto any number of
magnetic tapes mounted on one or more tape units. They can be ISO/ANSI Version 3 or
ISO/ANSI Version 4 volume label sets written in American Standard Code for Information
Interchange (ASCII) or IBM standard labels written in EBCDIC.
Attention: Because IEHINITT can overwrite previously labeled tapes regardless of
expiration date and security protection, IBM recommends that the security administrator
use PROGRAM protection with the following sequence of RACF commands:
RDEFINE PROGRAM IEHINITT ADDMEM(‘SYS1.LINKLIB’//NODPADCHK) UACC(NONE)
PERMIT IEHINITT CLASS(PROGRAM) ID(users or group) ACCESS(READ)
SETROPTS WHEN(PROGRAM) REFRESH
(Omit REFRESH if you did not have this option active previously.)
IEHINITT should be moved into an authorized password-protected private library, and
deleted from SYS1.LINKLIB.
To further protect against overwriting the wrong tape, IEHINITT asks the operator to verify
each tape mount.
