I want to confirm that both the drives in our system are correctly added to the RAID 1 array on the server. The RAID card is a Dell PERC H710 controller.
From the iDRAC interface, it shows one drive as "Online" and one drive as "Ready":
However, from the PERC H710 BIOS utility it shows both drives as "Online":
Why does the iDRAC status not show both drives as "Online"? This possibly implies that one of the drives is not active in the array, though the BIOS utility contradicts this.
