Table 55 redundancy properties
Name Type Description
redundancy-mode 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.
redundancy-

uint32 Numeric equivalents for redundancy-mode values.
• 2: Active-Active ULP
• 3: Single Controller
• 4: Failed Over
• 5: Down
redundancy-
status
string • 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.
