redundancy
This basetype is used by show redundancy-mode on page 232.
Table 91. redundancy properties
Name Type Description
redundancy-mode string The operating mode of the system, also called the cache redundancy mode.
● Independent Cache Performance Mode : For a dual-controller system,
controller failover is disabled and data in the write-back cache of a controller
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.
