We used to run tape decks on all our HP servers via the cciss scsi
controller, but now only have one. For them we had to 'engage' the tape
deck before it became visible to the system. We modified
the /etc/rc.local file so that this would occur at each system boot.
Below is the script we used for this, you may well need to do something

   test -f /proc/driver/cciss/cciss2 && \
     echo 'engage scsi'  >/proc/driver/cciss/cciss2 2>/dev/null
