Onboard Administrator module replacement and stored settings
When replacing an Onboard Administrator or if a failure occurs when using redundant Onboard
Administrators:
Removing an Onboard Administrator module in a Superdome 2 enclosure with a redundant
Onboard Administrator module installed results in the other Onboard Administrator module
immediately becoming the active Onboard Administrator if it was the standby Onboard
Administrator. Only the network settings of the replaced Onboard Administrator network
settings are lost.
If Onboard Administrator complex firmware versions are identical, manually update the
replaced Onboard Administrator network settings using the Insight Display. The replaced
Onboard Administrator module gets automatically synchronized on all enclosure settings by
the active Onboard Administrator.
NOTE: If the enclosure IP mode is enabled, then both Onboard Administrators have the
same network settings and no manual update is required.
If the complex firmware versions are not identical, the Onboard Administrator GUI and
Onboard Administrator CLI can be used to synchronize the firmware versions to the most
recent version in the modules, followed by synchronization of the active Onboard Administrator
configuration settings to the new standby Onboard Administrator module.
