Dwight, looking at my output I notice an additional line, which is
        missing your output:

   comp avail status..........Primary library manager installed.
                              Primary library manager available.
                              Primary hard drive installed.
                              Primary hard drive available.
                              Secondary hard drive installed.
                 this -->     Secondary hard drive available.
                              Convenience input station installed.
                              Convenience input station available.
                              Convenience output station installed.
                              Convenience output station available.

Maybe is only the atldd.driver version (4.0.7), and I hope for you that
"installed" alone means also mirrored.
