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.

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. show controllers 211

Failed Over to This Controller

Indicates whether the partner controller has failed over to this controller:

•

: 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

Failed Over to This Controller

Yes

, a reason for the failover appears; otherwise,

Not applicable

appears.

Health

•

Fault

•

Unknown

Health Reason

If Health is not

, this field shows the reason for the health state.

Health Recommendation

If Health is not

, 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.

•

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.

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.
