◦ General Failure—The array controller has failed.
◦ Cable Problem—The array controller has a cable problem. Check all cables to the
controller.
◦ Powered Off—The array controller does not have power. Replace the controller and

◦ Unknown—Indicates that the Storage Agents are unable to determine the status of the
controller. You may need to upgrade the Storage Agents.
• Current Role—Displays the array controller's current role for duplexed array controllers. The
following values are valid:
◦ Not Duplexed—This array controller is not duplexed.
◦ Active—This duplexed array controller is the active controller.
◦ Backup—This duplexed array controller is the backup controller.
◦ Unknown—Indicates that the Storage Agents are unable to determine the role of the
controller. You may need to upgrade the Storage Agents.
• Redundancy Mode—Displays the redundancy type for the controller. The following values are
valid:
◦ Not Redundant—This array controller is not in a redundant configuration.
◦ Driver Duplexing—The array controller is using a controller duplexing algorithm
implemented exclusively in the operating system driver.
◦ Firmware Active/Standby—The array controller is using an active/standby algorithm
implemented in the controller firmware and the operating system driver.
◦ Firmware Primary/Secondary—The array controller is using a primary/secondary
algorithm implemented in the controller firmware and the operating system driver.
◦ Firmware Active/Active—The array controller is using an active/active algorithm
implemented in the controller firmware.
◦ Unknown—Indicates that the Storage Agents cannot determine the redundancy type for
the controller. You may need to upgrade the Storage Agents.
• Redundancy Error—Displays the redundancy error for the controller. The following values are
valid:
◦ No Failure—No failures have been detected.
◦ No Redundant Controller—No redundant controller is installed.
◦ Different Hardware—The other controller indicates a different hardware model.
◦ No Link—A link to the other controller could not be established.
◦ Different Firmware—The other controller indicates a different firmware version.
◦ Different Cache—The other controller indicates a different cache size.
