We've got a Dell Poweredge T420 with PERC H710 RAID Adaptor.
It has 5x drives with the status' as shown below: - 2x RAID1 (Boot) Device0: OFFLINE Device1: Online - 3x RAID 5 (Data) Device2: Online Device3: Online Device4: Online
Initially it stated 'Forign configuration found' on boot & no boot device could be found. I imported the forign configuration & now it tries to boot into Windows but bluescreens after a few seconds & reboots.
If I boot into Windows (2008) Recovery mode, it does not list any disks initially. I tried loading the driver for the RAID controller and then the reocvery console says: "The device is not ready for use: its door may be open. Please check the drive \Device\Harddisk2\DR1 and make sure it is inserted and that the drive door is closed"
I can't be 100% sure I'm using the correct driver though as there seem to be several different versions/variations.
It seems strange that Windows tries to boot and then bluescreens (so I presume it's reading the boot drive to some extent) but in the recovery console it can't seem to see the drive at all.
Also, when I reboot, the RAID controller looses the imported forign configuration and gives the same 'Forign configuration found' message as before.
The LED on Device0 is flashing orange/green slowly The LED on Device0 is flashing orange more quickly
