Support During Stack Formation, Stack Merge; And Stack Split - Dell PowerConnect B-FCXs Configuration Manual

When the Standby Controller is fully synchronized, the system will be ready for a switchover or
failover.
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 illustrated below, the show stack command output will indicate whether there is a runtime
configuration mismatch.
