Subject: mptspi only sees first LUN

I'm not subscribed; please Cc me if you reply.

I've got an Arena Maxtronic SA-6640S RAID cabinet that exports
four array slices as "virtual" disks (same SCSI ID, but a different
LUN for each slice).  However, the mptspi driver in Linux is only
seeing the first LUN.

I am running Debian, and I have tried with etch kernel 2.6.18-6-k7
and with lenny kernel 2.6.24-1-686.  Both give me the same results.

I'm confident that the LUNs are there, because when the computer is
booting, I can see them as devices in both the BIOS setup ("press F2")
and in the LSI SCSI controller's scan (if I don't "press Ctrl-C").
This is all before GRUB loads.

The computer itself is a Sunfire server.  I don't have the model number
handy, but I can find out if needed.

Here are the details from the 2.6.24 kernel.  2.6.24 shows the first
LUN of the RAID array as sda, and then the two internal SATA disks
as sdb and sdc.  2.6.18 found the SATAs as sda and sdb, and then the
first LUN of the array as sdc.  Neither one sees the other three LUNs.
