IBM Tape Diagnostic Tool (ITDT) v7.0 offers multiple functional capabilities that simplify the task of maintaining IBM tape products.
Perform task automation using the ITDT scripting interface.
The IBM Tape Diagnostic Tool incorporated the original “IBM Tapeutil” and offers a common interface on all platforms for the Tapeutil-interactive and -scripting functions.
Note: The term tapeutil is a synonym for the tool that was delivered with the device driver. ITDT supports and replaces the tape utility program (tapeutil) provided by the IBM Tape Device Driver.
Если вкратце, то ITDT — это такой швейцарский ножик, и одно из лезвий — tapeutil. 🙂
