Configuring your cluster with hostnames

You must ensure that your computer hostname is configured correctly before you set up Telco Network Cloud Manager - Performance clusters.

About this task

Make sure that all nodes can resolve all cluster addresses.

Procedure

Make sure all the hostnames of the servers in your cluster are DNS resolvable.
Run the following command with your server name to check that the server is configured correctly:
```
nslookup myserver-worker01.ibm.com
Server:         10.60.90.206
Address:        10.60.90.206#53

Name:   myserver-worker01.ibm.com
Address: 10.210.117.34
```
Note: If you do not see name of the server in the output, it is not DNS resolvable.
Repeat for all servers in the clusters.
