Amazon is scheduling instance retirement for instance used to host usrcmd-mongod-01. To prevent disruption / degradation of availability we'll stop-start the instance prior to the instance retirement scheduled by Amazon on July 10th. No other actions should be needed since usrcmd-mongod-01 is currently acting as a secondary db.
