Initialize Tape (option 4.12)

Use Initialize Tape (option 4.12) to initialize a labeled or unlabeled tape. The tape is rewound, and the appropriate header information is written.

When you select Initialize Tape, the Initialize Tape panel shown in Figure 1 is displayed.

To initialize with labels, File Manager writes a volume label set in either IBM® standard format or ANSI type 3 or 4 (ASCII) format. For NL initialization, File Manager writes a single tape mark.

Specify a DDNAME for the tape. If the DDNAME is not allocated, you are asked for allocation information. To check existing labels on the output tape before creating the new label set, specify the appropriate label value on the tape allocation panel. Specifying BLP initializes the tape unconditionally.

When Initialize Tape has finished, the tape remains positioned after the label set.

It is recommended that you unload the tape and reallocate it with the new volume serial number, to make your system aware of the new volume serial number.

You can initialize a tape with ANSI type 3 or 4 labels to be used with ASCII files. You can also specify a file identifier to be used for the file header label. Omit the volser to initialize an NL tape.

You can add a scaling capacity to the tape provided the function is supported by the hardware. The scaling capacity limits the amount of the tape actually used.
