|So you have a hardware raid controller which you appear to be using but not using for a hardware raid. You are doing software mirror instead.|
Clearly someone did not understand proper server setups. This resulted in the waste of a raid controller.
"My point was if Windows recognises Hard Discs why does recovery console ask for Hard Disk Drivers when no OS is present in dialogue box during recovery test."
Recovery console is a bare engine. Any special parts like a sata raid controller driver will need to be added during the first phase of recovery which is when you are seeing all of the hardware drivers being loaded. You usually do this by hitting f6 and giving the system the driver via floppy disk.
If a hard drive controller driver is needed and not supplied recovery ends with no drives found. Which sounds exactly like what you are encounting with no OS.
Note: you can slipsteam the OS version you have now with the driver and burn a new server cd that will not need you to add the driver.
Does this answer your question?
