5.8.2 Dual-Redundant Controller Configurations
Subsystem configuration and code patch information is stored in the NVMEM
of both controllers of a dual-redundant configuration. If one of the two
controller modules in a dual-redundant configuration needs replacing, no
configuration information is lost because the other controller has it. There is no
need to use the CLI command: INITIALIZE container-name
SAVE_CONFIGURATION, in fact, its use is discouraged.
The method of saving the configuration in dual-redundant controller
configurations is by using the CLI command: SET FAILOVER
COPY=controller (refer to HSZ50 Array Controller HSOF V5.1 CLI Reference
Manual for additional information). The act of placing the two controllers into
failover mode with this command ensures that the configuration in the primary
controller (the one that had the configuration placed in it) is copied to the
companion controller in the dual-redundant pair.
NOTE
Ensure you know which controller has the good configuration
information before entering this command. The device configuration
from the controller specified in the CLI command: SET FAILOVER
COPY=controller overwrites the information on the companion
controller.
