I am setting up replica set.
On master:
replSet = rs2 added to config file
~~~
> rs.initiate()
{
"info2" : "no configuration explicitly specified – making one",
"info" : "Config now saved locally. Should come online in about a minute.",
"ok" : 1
}
rs2:PRIMARY> db.unicorns.find(

{name: 'Horny'}

);
<', dob: new Date(1992,2,13,7,47), loves: ['carrot','papaya'], weight: 600, gender: 'm', vampires: 63});
rs2:PRIMARY> db.unicorns.find(

{name: 'Horny'}

);

{ "_id" : ObjectId("4e723bcffa1ff8e3080494cf"), "name" : "Horny", "dob" : ISODate("1992-03-13T12:47:00Z"), "loves" : [ "carrot", "papaya" ], "weight" : 600, "gender" : "m", "vampires" : 63 }

Ping SD2QVQ01VL shows
64 bytes from SD2QVQ01VL.SAKSDIRECT.COM (10.32.150.82): icmp_seq=2 ttl=64 time=0.194 ms

What is wrong in my setup?
Thanks in advance.
