I've got a Compaq DL380G1 with a Smart 5300 card (ciss).  I've got an

array plugged into port 1, and a tape plugged into port 2.  The BIOS

setup for the card sees everything, but OpenBSD doesn't see the tape,

nothing in dmesg.  I don't even see the second scsibus for ciss.  Any

suggestions?

[ message continues ]

talking to tape drives and such things behind raid controllers typically

takes a lot more work, and few of our drivers have support for that.

IIRC (and thats debatable as this is old memory) a number of the compaq

array cards do *not* support tape devices behind the scsi bus. it was

only intended for connecting further disks to.
i think its expected to see it in the bios though even if it can't be

used in pass-through configuration.
if this applies to your device, it will be documented in the 5300

technical info.
