Boot order of LSI MPT Fusion devices controllable?

Hello,

I am running mdk 10.0 with kernel 2.6.3-16 out of box on a dual opteron
250 system.  The system has a LSI logic U320 controller with 7 internal
disks on two channels.

We are upgrading our system by adding an identical server and a small
SAN so we can have an active passive failover cluster for MySQL.

I purchased quad port 2gbps fc cards from LSI as I have been very happy
with the performance of the SCSI cards we already own.  Upon install,
dmesg shows:

Well, the difference is that the fiber channel card seems to boot first,
and thus reorders the scsi bus.  If I attach the fiber channel cables to
the switch (making all of our storage visible) and re-probe the scsi bus
by hand using the /dev interface, access to the SAN is fine etc.  Upon
reboot with the fc connected, my system panics because now the root
drive is no longer where it thinks it should be (sda is now a device on
the fiber channel switch fabric).

Is there a way to control this process or to mitigate the problem?  I
really need the system to boot properly off of local disk whether or not
the fc is connected or the devices available.

Thanks,

Richard F. Rebel
