[SunHELP] Emergency: can NOT unload cartridge from L9 tape !!

[L]

I have SUN L9 tape driver connect to SUN 280.  Currently, I have problem
can NOT unload tape cartridge from L9.  I have been tried following
procedures still not work:

  % mt -f /dev/rst27 offl
/dev/rst27: no tape loaded or drive offline 

  I press unload button and LED green light blinking forever.

  I power off/on and redo the procedures still same.


Does anyone know how to fix it?


Thanks.
