UK-Mike,

It sounds like there is indeed an issue with the settings. When you boot the server currently, with a RAID 1 Mirror configuration it should display a message, as illustrated below,  just after the Dell logo screen during POST. Are you seeing the Raid 1 you configured in the Raid Volumes section?

If so, is the Status showing as Normal, like it does in the picture? If not, what is shown?

If it shows nothing below the Raid Volumes, then the array hasn't been configured. To ensure that the system is in in Raid Enabled Mode, follow the instructions below.

  1. Enter System Setup by F2 when you see DELL logo after starting the computer.
  2. Select System Configuration, and press .
  3. Select SATA Operation.
  4. Press key and then select the RAID On button. Click Apply.
  5. If the setting was changed from RAID AHCI or ATA to RAID On, a pop-up window displays. If the pop-up window displays, select 'Yes'. If the setting didn't change, the pop-up window will not display. 
  6. Press or select Exit. If prompted 'Are you sure you want to exit?' Select 'Yes'

After that then you can access the CTRL-I and configure the 2 drives. 

Let me know if any of this helps, or if I am misunderstanding what you are seeing.

Hi Dell-Chris H, thank for yours answer.

Yes, my Raid have normal status like in a picture, in BIOS choice "Raid on" mode.

Today i test  server with two other HDDs, Seagate 1Tb and everything is ok.

after install server 2008 r2, system going reboot and boot from raid. i don`t have problem with this HDDs.

I think problem with Compatibility Intel® RAID Controller and Western Digital HDDs.

Because a disk failed at first, a disk of the same model size was replaced and displayed as follows after configuration: After that then you can access the CTRL-I and configure the 2 drives.  Disk status shows rebuild. Let the CTRL +I interface after the rest of the night. Still rebuild state

Hello thanks for choosing Dell.

You can not mix those two, I'm afraid.
