Normal Unload Button
If the CTS’s EEPROM image includes the “normal” unload button
setting (default), the following actions occur when you press the
unload button. (These steps assume that a data cartridge is loaded
and that the CTS is ready.)
Note: If you have prevented media removal with a PREVENT/
ALLOW MEDIUM REMOVAL command, the CTS performs
no action when you press the unload button.
1. Any command or operation currently in progress is completed.
2. Any buffered information is written to tape, and an EOD mark
is written to indicate the end of data.
Note: In 8200 format, no EOD mark is written.
3. The tape is rewound to the physical beginning of tape (PBOT).
4. The tape is unloaded from the tape path.
5. The data cartridge is ejected.
Fast Unload Button
If the CTS’s EEPROM image includes the “fast” unload button setting
(optional), the following actions occur when you press the unload
button (assuming that a cartridge is loaded and that the CTS is ready).
Note: If you have prevented media removal with a
PREVENT/ALLOW MEDIUM REMOVAL command, the
CTS performs no action when you press the unload button.
1. Any command or activity currently in progress is aborted.
Note: If the CTS is performing a write operation when you
press the “fast” version of the unload button, the CTS
will abort the command after it writes to tape the last
logical block that was completely transmitted from the
initiator. However, any partially transmitted logical
blocks will be lost.
2. If necessary, an EOD mark is written to the tape to indicate the
end of data.
Note: In 8200 format, no EOD mark is written.
