using built on raid for intell s3200shv with rhel 5.1
the intel sh3200shv has both integrated intel and lsi setup for 6 sata drives.
first I tried the LSI. set up my vol as a raid 10 on four drives.
initialized the drives and set the boot.
installed rhel using a intel driver for rhel 5.1
everything went well
system reboots to message the two drives I'm not even using are bad and can not read them
since I have four drives they should be sda0 and sda1 in one raid and the mirror should be sdb0 and sdb1. rhel is complaining that drives sdb2 and sdb3 can not be read.
so we crash.
if I do the intel raid set up
again rhel loads fine
but when the computer reboots all I see is the word "grub" and the computer never loads.
never had a problem with add in cards from LSI before
any suggestions.

I followed instruction that are for the intel board on getting the drivers.
the dud file has every type of raid card that is acceptable to intel and rhel.
if you use one that is not correct rhel says no device for this driver so I would assume that when it excepts one and shows the type of raid to install it to this is the correct one.
rhel finds the volume I created and installs to it.
rhel seems happy on the install but not on the boot.

You are confusing two issues:
1) Do you have a SATA RAID where during boot you have an option to go into the bios of the LSI controller and setup the RAID 10?
2) Or Are you setting up Software RAID within the RHEL setup (mkraid)?
The confusion is when you mention intel drivers and LSI drivers.
From the description of your issue, it seems that after the install, the RAID 10 volume is not seen during boot.

intel cards come with two ways to hardware raid the built in raid card. Intel and LSI, when you choose one in the bios then you get the setup for the type you have choosen.
cntrl e for lsi
cnrtl i for intel
either way they are hardware raid
the lsi setup crashs because it can not read the mirror
intel setup will not go past the grub stage on boot up.
but I do think that rhel 5.0 can not see the raid correctly. like it does on a external raid card.
rhel will not tell you if there are any raid cards they do like, there response is that they no longer check any compatible devices only complete systems.
personally I'm beginning to wish we had never bought into the rhel system.
I would go with solaris but it refuses to see any part to the built on raid system.
trying to get a straight answer from rhel if there is any built in hardware support for raid cards is like pulling teeth from a chicken.
I do know that LSI sas cards load with no problem, but then I have sata drives on this system.

Here is the confusion, which option did you choose to setup the hardware RAID?
LSI or Intel?
If you choose to use LSI to create the RAID 10, do not use intel drivers to install the rhel.
When you installed the grub boot loader, on which drive was it installed?
Pull the undesignated SATA drives for the purpose of the install of the OS.
RHEL either sees the volume (raid 10) or it does not. The existance of the unafiliated SATA drives could be what is causing this difficulty i.e. the boot loader is installed on the MBR of the unsued drives.
Check the device boot order.
In RHEL, do you let it partition and setup the filesystem, or do you manually setup the partitions?
Is it possible that the HW RAID 10 and the two remaining drives are grouped into an LVM volume?
LSI or Intel?

the intel setup only works for microsoft
the built on lsi does not support raid 5 even though intel sells it as a raid 5 card
rhel50 crashes unless you install the lsi drivers from intel.
if you set it up as raid 10 rhel sees the raid volume just fine,
formates the drives
installs grub on the first drive of the first raid
there are no unaffiliated drives in the computer.
rhel sets up the drives
as for the lvm volume I will have to look

when you use the built in raid the bios shows the raid as a boot option.
rhel 5 finds the raid says it is installing the grub boot and formats the dirves
the system will not boot
called intel, who ever they are paying to do there tech support doesn't know there ass from a hole in the ground.
abandoned the built on raid for a 3ware card, rhel is happy, I'm happy.
the only conclusion I can come to this mess is never buy an intel board. I have three of them, they boot so slow that you swear they didn't come on at all, windows xp works fine on them, intel sucks when it comes to linux.

Oh, don't say that. Those are very fine mobos - but raid - it's fake raid, what have You expected?

I am awarding arnold the points because he tried and for anything but a intel built on raid probably was on the right track.
When you were configuring the install, was the RAID 10 drive available? Was the RAID 10 drive the destination to which you installed the OS?
The issue is that you used LSI to setup the RAID 10, but you are loading/installing RHEL 5.1 using the Intel Drivers which likely only see the two remaining drives.
Regarding the drives, you should actually see only three drives within the OS sda (raid 10) and sdb and sdc (sdc and sdc are the remaining pair).
you may run into a problem that the grub is installed on the pair rather than on the RAID 10.
