Failed Over to This Controller
Indicates whether the partner controller has failed over to this controller:
• No: The partner controller has not failed over to this controller.
• Yes: The partner controller has either failed or been shut down, and its responsibilities have
been taken over by this controller. There will be a delay between the time that the value of
Status becomes Down for one controller and the time that the value of Failed Over to
This Controller becomes Yes for the other controller. This time period is the time that it
takes for a controller to take over the responsibilities of its partner.
Fail Over Reason
If Failed Over is Yes, a reason for the failover appears; otherwise, Not applicable appears.
Health
•
OK

Health Reason
If Health is not OK, this field shows the reason for the health state.
Health Recommendation
If Health is not OK, this field shows recommended actions to take to resolve the health issue.
Position
Position of the controller in the enclosure:
• Top: The controller is in the top slot.
• Bottom: The controller is in the bottom slot.
Phy Isolation
Shows whether the automatic disabling of SAS expander PHYs having high error counts is enabled
or disabled for this controller.
• Enabled: PHY fault isolation is enabled. This is the default.
• Disabled: PHY fault isolation is disabled.
Controller Redundancy Mode
Shows 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.
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.
Controller Redundancy Status
• 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.
