Manual steps after the recovery process
After you recover the backup images that were taken from the hidden MongoDB nodes, the hidden nodes become primary nodes. Update all such primary nodes in the shard list and restart the mongos process using the following command:
db.getSiblingDB('config').shards.updateOne({ "_id" : "shard1" },{ $set : { "host" : "ShardName/repl1.example.net:27018,repl2.example.net:27018,repl3.example.net:27018" } })
After the recovery process is complete, manually add the secondary nodes to the cluster.

After the recovery operation, the mongod or mongos process is started using the configuration files from the
/tmplocation. Ensure that you move the configuration files to a selected location and restart the services from that location.You can add more MongoDB configuration parameters if there are any changes from the backup data that is restored.
