Hi,

We have some HP (and older Compaq) servers with SCSI tape decks in them,
using the HP scsi array controller ('5i', it uses the cciss driver). The
tape decks weren't recognised until we added the following to
/etc/rc.local:

  test -f /proc/driver/cciss/cciss0 && echo 'engage scsi'
              >/proc/driver/cciss/cciss0 2>/dev/null

That's all on one line. Upon rebooting you then get the

   Attached scsi tape st0 at scsi0, channel 0, id 0, lun 0

message.

There is info on SCSI tape decks in the kernel source docs, you will
need to install the kernel source rpm for these though. Then look at:

  /usr/src/linux-2.6.6-1.435/Documentation/cciss.txt

Needless to say if you have different hardware then you may need to try
and find the relevant file.
