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.
