0In

The data cartridge is unloaded.* If there is data in

the write buffer, the data is written to tape. Then,

the tape is rewound to PBOT and unloaded from

the tape path, and the data cartridge is ejected

from the CTS.

1In

The data cartridge is loaded and positioned at

LBOT. If the data cartridge is already loaded and

there is data in the buffer, the data is written to the

tape before the operation is performed.

Note: If the tape is already loaded, positioned at

LBOT, and there is no data in the buffer, no tape

motion occurs.

* The unload operation is performed even if the PREVENT/ALLOW MEDIUM REMOVAL

command was issued with the Prevent bit set to 1; however, the data cartridge is not

ejected from the CTS.
