CTTTPI – Tape Initialization, Information Mapping, and Tape Erasure

The CTTTPI utility provides the following major functions:

Table 391 CTTTPI Functions

Function	Description
Safe Tape Initialization (INITT)	Initializes tapes and cartridges. Checks that a volume is not active before initializing it, thereby ensuring that active volumes are not accidentally initialized.
Media Information Mapping (TAPEMAP)	Produces a detailed report about the logical and physical content of a volume including logical files, labels, tape marks and unreadable areas (I/O errors).
Safe Tape Erasure (TAPERAS)	Physically erases the contents of a volume. Checks that a volume is not active before erasing it, thereby ensuring that active volumes are not accidentally erased.

These functions are described in detail below.

Multiple jobs or started tasks can run the CTTTPI utility in parallel on separate tape drives for distinct ranges of volume serial numbers.
