I have 2 problems


When i try to check the sharding status from demo1 db on server1 i get below error 



  use demo1
  switched to db demo1
  sh.status()
  printShardingStatus: this db does not have sharding enabled. be sure you are connecting to a mongos from the shell and not to a mongod.



I have inserted couple of records which did not get replicated to server2. what am i doing wrong?
sh.status() can only be executed on your mongos. As you posted your "sharding status" with sh.status() in your question yourself. You can't do that on the separate shards.
Sharding is for distributing your documents. For example documents ABC on shard0000 and documents DEF on shard0001. So Sharding is not Replication. If you want to replicate your documents then you need to look at 'How to setup a mongodb replica set' : http://docs.mongodb.org/master/tutorial/deploy-replica-set/
