I looked around the forum and did not see anything that answers my question. If you can help, please chime in...
New HP Proliant ML150 G5 which is setup and running SME 7.3 just fine. Installation went very well. In fact I did an AFFA Rise installation which worked impressively.
The server has (2) SATA drives which are mirrored in a RAID1 via SME standard setup.
The problem I am having, or think I am having, is the drive operations appear to be slow. Both drives are recognized as hda and hdc respectively. I had expected them to be recognized as sca and scb. I did NOT load SATA controller drivers. The SATA controller is a SATA E200. Do I need to load the driver, which ships on a CD and is a RHEL4 RPM (I assume that is compatable with SME 7,3).
If I load the rpm, will it affect the installation and data???
The server has an embedded SATA RAID RAID controller which I am not intending on using. Any advantage in using it over the SME software RAID??
This is a production box and I prefer to minimize risk.
Thanks for any assistance.

if you are not using the raid controler the drivers do not need to be loaded
you mean sda and sdb or sdc they should be sda and sdb you must have one of the drives as a slave and the dvd/cdrom as a master for it not to be that way
hda for ide and sda for sata or scsi you may have it setup if the bios has it as sata setup in ide mode
by the way the onboard sata raid controler works fine as i have setup a few ML150 with both centos and sme
PS the rel drivers should work ok as sme is based on centos 4.6 which is REL4 but as you are not using the raid controler you don't need them
when you say slow can you explain a bit more

That's an indication, I believe, that the drives are configured in the BIOS as PATA or legacy mode. If so, I suspect you may not be able to fix it without a re-install.

as i said and charlie said would be correct if the bios has that in it if it does and you switch back to sata mode not share the wording as i have never really had to play the the HP ML BIOS chralie is right you will need to do an reinstall
use the raid on the ml150 it is quite good
and make sure that one hard disk is connected to sata 0 or 1 and the second one is connected to sata 1 or 2 and the cdrom if sata is on number 3 or make it a slave if it is ide
so you will ger sda sdb and sdc setup up plenty of the ML150 and the ML110 they are fine serversshould give you many years out of them we have a few that are still fine after 5 or more years

Thank you for the information. I will do a reinstall and report back.
You have confirmed what I thought, but I was only guessing.

Report Back: The server really rocks....
Changed the HD's to SATA in the BIOS. Utilized the embedded RAID. It really screams now.
Thank you both for your quick responses and sage advice.
I did an affa transfer to a temporary machine, reconfigured the ML350 and did another affa transfer. Almost no downtime. It took a bit of time, most of which was building the RAID and doing the intial affa save. Actual downtime was less than 5 minutes while "rising" affa each time.
SME is working as advertised. Tip of the hat!!!
