This CucsFsmFsmStageStatus field reports the current lifecycle status of the FSM that tracks state transitions of that FC SAN border uplink as it comes up or is reconfigured — for instance whether it is in progress, has completed, or has failed. This is the primary field an admin watches to know at a glance whether an operation on this object is still running or has reached a terminal state. For example, an admin polling this OID during a fabric reconfiguration would expect to see the status move from in-progress to completed, and would investigate if it instead reports a failure.
