What is the correct first step for configuring RAID 1 in a Dell EMC PowerEdge server?

The correct first step for configuring RAID 1 in a Dell EMC PowerEdge server is to start by selecting the Controller from the Device Settings. This step is essential because you need to access the specific RAID controller that manages the physical disks in the server. By selecting the controller, you can then navigate to various settings that pertain to RAID configurations. This foundational step ensures that you are working within the correct environment to set up and manage RAID arrays effectively.

Once the controller is selected, you can proceed to configuration management, choose the RAID level, and select physical disks involved in the RAID 1 setup. However, without initially selecting the correct controller, you lack access to the necessary tools and options needed to configure RAID settings properly, making this a critical first move in the process.
