Name
Type
Description
redundancy-mode
string
The system’s operating mode, also called the cache redundancy mode.
•
Independent Cache Performance Mode
: For a dual-controller system,
controller failover is disabled and data in a controller’s write-back cache is
not mirrored to the partner controller. This improves write performance at the
risk of losing unwritten data if a controller failure occurs while there is data
in controller cache.
•
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-mode
values.
•
1: Independent Cache Performance Mode
•
2: Active-Active ULP

redundancy-
status
string
•
Redundant with independent cache
: Both controllers are
operational but are not mirroring their cache metadata to each other.
•
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.
