Notes:
1. The tape does not have to be ready when a Prevent command is issued. The
Prevent Medium Removal command disables only the unload switch. Unload
commands from the host are still permitted.
2. Allow Medium Removal returns status to the host only after all buffered data is
written on tape (the tape must be loaded and ready).
3. Medium removal is allowed only after all initiators that issued a Prevent have
issued an Allow Medium Removal command.
4. A reset condition clears the prevent condition.
