The Management Agents Could Not Establish a Domain


The HADB management system is dependent on UDP Multicast messages on multicast address If these messages cannot get through, the createdomain command fails with the following message:

The management agents could not establish a domain, please check that the
hosts can communicate with UDP multicast.

Possible causes include:

Solution 1

If the hosts have several network interfaces on different subnets, the management agent must be configured to use one of the subnets. Set the ma.server.mainternal.interfaces attribute.

Solution 2

Configure the needed network infrastructure to support multicast messages.
