Runtime configuration mismatch
In some cases, such as a runtime configuration mismatch between the Active Controller and
candidate Standby Controller, the Standby Controller cannot be assigned by the Active Controller
unless the candidate Standby Controller is reloaded.
As shown in the following example, the show stack command output will indicate whether there is a
runtime configuration mismatch.
