Figure 8-56 PREVENT/ALLOW MEDIUM REMOVAL CDB
This command enables or disables the unloading of the tape cartridge.
Prevent
If this bit is set, the Unload button on the drive front panel is effectively disabled, and
the UNLOAD command will not unload the media or the cartridge. The Prevent/Allow
status in the device is maintained separately for each initiator.
When the Prevent bit is set to zero, then the Prevent state corresponding to that initiator
is cleared. Only when all initiators have cleared their Prevent state are the Unload
button and Unload commands enabled again. By default after power up, hard reset, or
Bus Device Reset message, the Prevent Medium Removal function is cleared.
If a Media Loader is present, the Move Medium command will not be allowed to
remove a cartridge if PREVENT has been selected.
