Type Description
The system's operating mode, also called the cache redundancy mode.
string
• 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.
• Fail 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.
string

2: Active-Active ULP
•
3: Single Controller
•
4: Fail Over

5: Down
• Redundant: Both controllers are operational.
string
• 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.
