How to interpret nodetool status output?

Question

I run nodetool status on an instance of Cassandra 2.0.3, the output shows:

 Datacenter: eu-west =================== Status=Up/Down |/ State=Normal/Leaving/Joining/Moving -- Address Load Tokens Owns Host ID Rack UN xx.xxx.xxx.xxx 154.81 KB 256 33.8% bcfb1057-60d7-4d94-b277-a1e8c0f55cf4 1a 

I searched all the manuals available on the Internet, but none of them explain what UN means.

What does UN mean?

Answer 1

U = Up N = Normal

This is the first letter of status, followed by the first state letter.
