Checking Controllers

Checking Controllers

Controllers of the storage device are responsible for running storage applications, implementing storage mechanisms (StoragePool, LUN mapping, and striping), and managing alarms. You can learn about the health and running status of a controller by checking its status information on the DeviceManager.
