Redhat 7.2 on the LSI u320 (PE1750) Jason_Mick at

This looks like it should get it done for you.  The SCSI chip is LSI53C1030
Ultra320 SCSI controller.  I checked on LSI Logic's site and there is a
driver for the card. I have never attempted to use it so I have no idea as
to how well it will work.  
Driver file:

Description : Driver update disks for:Red Hat 7.0, 7.1, 7.2 (32 bit and 64
bit), 7.3 and 2.1ASE SuSE 7.2, 7.3 and 8.0 Caldera 3.1 and 3.1.1 For Red Hat
8.0 and SuSE 8.1, the user must install using the bundled driver. Upgrades
may be performed using the appropriate RPM. 

Available at when you have to select a product just choose
the LSI22320 (320).  That should take you to the driver.  The read me shows
for the 53c1030 controller and has extensive instructions on getting it

Right.  You need the 'mptfusionh' driver, which is the LSI SCSI adapter
driver, not 'megaraid', which is the RAID driver (since you don't have the
RAID controller).

Now the hard part - finding a copy of mptfusionh for RHL7.2 that knows about
the IDs on a PE1750... We've got a driver disk for RHEL2.1 AS posted to (search for R56758), but not for 7.2.

And so far, no one has generated a DKMS package for mptfusionh, so building
that driver disk by hand is time-consuming.  Can you run RHEL2.1 instead?
