installed.
A medium-access command has been sent to the drive
while a cleaning cartridge was loaded.
Action: 1. Terminate the current I/O, and return the appropriate
error.
2. Send a message to the console indicating that a
cleaning cartridge is in the drive and a cleaning
cycle is being performed.
3. Prompt the user to wait for the cartridge to be
ejected. In a library, the cartridge will be ejected
when requested by the library or host. In an internal
or external single drive, the cartridge will be ejected
automatically.
4. Prompt the user to proceed with the next
application-specific activity.
5. Log the cleaning cycle in the system log.
3A 00 Medium not present A medium-access command has been received when no
cartridge is in the drive.
Action: As a minimum, issue a message to the console
indicating that a drive is present but no tape is loaded.
3A 04 Medium not present,
Media Auxiliary Memory
accessible
A media access command has been received when the
tape has been loaded but not threaded. This will be
reported if the hold bit of the
LOAD CDB was set or the
Autoload field in the Control mode page is non zero.
3E 00 Logical unit has not
self-configured yet
This is set during power-up when it is not possible to
send medium-access commands to the drive because
mechanism tests are being executed. When the tests are
complete, the additional sense changes to 3A 00h,
04 01h or 04 02h depending on whether a cartridge
was present at power-on.
Action: 1. Issue a message to the console indicating that the
drive is powering up.
2. Effectively poll the drive until the drive transitions to
another state, at which point either execute the
command or terminate the I/O.
