Specify to write to the end of the tape

On the Unload Job Select window, you can specify to write to the tape until the end of the device with the Write/read to/from tape until end of device check box. When a tape device is full, you are prompted to provide the next tape, until the unload job is complete.

Important: If you select this option, you must also select it when loading from the Load Job window or specify the -Z option from the command line; otherwise, the loaded and unloaded data might be inconsistent.

If you check this check box, it supersedes any tape size information you enter in the Device-Array Definition window or at the command line.

Important: You must provide the same tapes in the same order on the same devices for both unload jobs and load jobs to ensure consistency.
