LoadMaster cannot retrieve the servers' hostname

 

Information

 

Summary:

LoadMaster is not able to resolve the hostname of the RS's.

Environment:

Product: LoadMaster.

Version: Any.

Platform: Any.

Application: Any.

Question/Problem Description:

The LoadMaster cannot do a reverse DNS lookup to get the server's hostname.

Steps to Reproduce:  
Error Message:  
Defect Number:  
Enhancement Number:  
Cause: Servers don't have a PTR record on the DNS server.
Resolution:

The most commom reason of the LoadMaster not being able to do a reverese DNS lookup is because a PTR record doesn't exist for the servers.

To confirm this, you can run nslookup <Server's IP> against your DNS server and this should return the server's hostname.

Once verified, from the LoadMaster's WUI, go to System Configuration > Network Setup > Host & DNS Configuration > DNS NameServer and make sure you're using the correct DNS servers.

Then, enter your Domain under Add Search Domain. Once done, click on Run Resolver Now under DNS Resolver Options and this should solve the issue.
