Description
operation-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
: There is only a single controller in the enclosure.
•
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.
