HP Proliant ML350 G5 Boot Issues

Hello,

We are trying to have a HP Proliant ML350 G5 Server boot and install Windows onto a SATA hard drive that we have connected directly to the motherboard.  This is so we don't use any room on the RAID 5 setup that is for storage, and if the drive fails, we can simply replace it with a backup of the drive with no fuss.

However, when we try to install, it says, "This computer's hardware may not support booting to this disk" with details indicating that the disk's controller may not be enabled in the BIOS."

How do I get around this issue?

You can't

The server will always boot from the raid controller rather than the Sata ports and it should have 2 drives for the mirror.

Installing an OS on a RAID5 array is a disaster waiting to happen.

alexgreen312,

The server will have 8 1TB NAS drives in RAID 5.  That is already set up and working.  We are trying to avoid installing the OS on the array.


Manjunath,

I have gone into the BIOS looking for an enable for the SATA, but I have not found one.  When I go to install Windows though, it DOES see the hard drive.  I will take a closer look to see if I can find an option such as the one you posted.  By the way, the Array controller is the E200i I believe.

Can't you add the SATA drive to the RAID controller, and configure it as a single disk (maybe you need to set it up as a single disk RAID 0 array)? Or much better, if there is a further free disk-bay available, add another same disk, and setup RAID 1 to install your OS to.

rindi,

My Boss wants (if possible) all 8 drives in the array to be used for storage only.  So, we are trying to make this work without having to sacrifice a hard drive in the array for the OS.

Here's some pictures of the BIOS.  I couldn't find any helpful settings Manjunath.

What I mean, is the RAID controller already fully used up? can't you add the 2 (or 1) OS disks to the RAID controller and add a 2nd array?

rindi,

Sorry.  Let me try to make it easier.

This has 8 bays in the front for 2.5" HDD's.  My boss has 8x1TB NAS drives installed in the bays and has all 8 drives set up as 1 logicial drive (RAID 5).

He's trying to use a 120GB 3.5" SATA HDD hooked up to the motherboard directly.

Does that mean you RAID controller has 8 ports maximum? Or does it have more than that? If it only has 8 ports, then you must check whether you can change the boot order so the IDE/SATA port has priority over the RAID controller. Many BIOS's also allow you to change the first harddisk to boot from, and in that case you should see the RAID array and the single disk, which probably is after the RAID array.

But if the RAID controller has more than 8 ports, you should connect your boot disk to the RAID controller, and not the internal SATA port. That disk should then appear in your RAID controller's setup utility, and you should be able to set it up as an Array and be able to boot from it.

alexgreen312,

Sounds like my boss wants to go with just installing the OS on the RAID, and partitioning one part for the OS, and the rest for storage.  You mentioned that is 'a diaster waiting to happen'.  Why is that?

Because if you have a drive failure the RAID5 array will then move over to it's parity section of the array, the windows OS doesn't like that at all and even when you replace the disk the OS has a tendency to BSOD until you reinstall it.

I've had it happen 3 times to me, no I didn't build said servers :)

Thank you for your help, but we ended up added a PCI SATA controller board and installed Windows onto a hard drive on there.  Not the solution I was looking for, but at least it means we can leave the RAID as 8X1TB in RAID 5.  Thank you for your help!
