Lenovo ThinkServer RAID Drives Not Showing Up:

Here's the situation.
I have a Lenovo ThinkServer TS100 with ServeRAID-MR10i SAS/SATA Controller.
I put 2 x 1TB SATA hard drives in it and configured it for RAID1, then installed Windows Server 2008 without issue.
I then decided that before I put the server into production, I should use Enterprise-class HDDs instead of regular consumer drives so I ordered 2 x 1TB enterprise drives (brand new).
I took the old drives out and put the new ones in.
Upon booting it mentioned something about missing all of the disks from the previous configuration .
This seemed normal to me so I clicked C to load the RAID configuration utility and setup the 2 new drives in RAID1.
I can set them up as RAID1 without issue and before exiting the utility I can see they show in green text stating they are online. You can also see the 1 virtual drive with 930GB in green with a status of Optimal.
When I reboot the system, I get the same warning that I got before about the disks missing from the initial configuration etc.
When I click any key to go passed that and try to install the OS, the drives don't show up.
When I load the ThinkServer CD and try to install the OS that way, I get a message that no drives are detected.
When I restart and click C to go back into the RAID setup utility, the 2 drives show up in blue text as "Unconfigured Good".
I don't know what I'm doing wrong here.
Any help would be appreciated.

Go into the RAID configuration BIOS and delete the configuration (which is the step you missed first time when you just created a new array without deleting the old one). MR10i is a LSI controller and it stores the configuration on the disks and on the cad itself so you need to delete the config from the card.

Thank you.
Although I'm relatively certain I did try clearing the configuration at least once during the many attempts I made at getting this working, I did it once more and then created a new virtual drive using the "manual" method instead of the "automatic" method.
Not sure what was different this time around but when I rebooted, I saw that one virtual drive was detected which meant I was good to go.
While I wouldn't say that your comment was solution per say, it did confirm that nothing was broken or incompatible which led me to trying one more time.
Thanks!
