redundancy This basetype is used by show redundancy-mode. Table 54 redundancy properties Name Type Description redundancy-mode redundancymode-numeric redundancystatus redundancystatus-numeric controller-astatus controller-astatus-numeric controller-aserial-number controller-bstatus controller-bstatus-numeric controller-bserial-number string uint32 string uint32 string uint32 string string uint32 string The system's operating mode, also called the cache redundancy mode. • Active-Active ULP: Both controllers are active using ULP (Unified LUN Presentation). Data for volumes configured to use write-back cache is automatically mirrored between the two controllers to provide fault tolerance. • Single Controller: The enclosure contains a single controller. • Failed Over: Operation has failed over to one controller because its partner is not operational. The system has lost redundancy. • Down: Both controllers are not operational. Numeric equivalents for redundancy-mode values. • 2: Active-Active ULP • 3: Single Controller • 4: Failed Over • 5: Down • Redundant: Both controllers are operational. • Operational but not redundant: In active-active mode, one controller is operational and the other is offline. In single-controller mode, the controller is operational. • Down: This controller is not operational. • Unknown: Status information is not available. Numeric equivalents for redundancy-status values. • 1: Redundant • 3: Operational but not redundant • 4: Down • 5: Unknown • Operational: The controller is operational. • Down: The controller is installed but not operational. • Not Installed: The controller is not installed. Numeric equivalents for controller-a-status values. • 0: Operational • 1: Down • 2: Not Installed • Controller module serial number • Not Available: The controller is down or not installed. • Operational: The controller is operational. • Down: The controller is installed but not operational. • Not Installed: The controller is not installed. Numeric equivalents for controller-b-status values. • 0: Operational • 1: Down • 2: Not Installed • Controller module serial number • Not Available: The controller is down or not installed. redundancy 431
