Multiple NIC cards can cause problems during System Management
 Technote (troubleshooting)
 
Problem(Abstract)
Multi-homed machines fail during certain System Administration functions, throwing an error: ADMU0036E: The Deployment Manager cannot lookup by name.
 
Cause
When a machine has multiple network interface cards (NIC), each with it is own IP address, it is called "multi-homed". During certain System Administration functions, such as addNode, the function InetAddress.getByName might be called to resolve the IP address of the machine in which the administration is taking place.

This can cause a conflict if the IP address returned is different from what the Deployment Manager is expecting. If this happens, the IP address comparison will fail and we will throw an AdminException:

ADMU0111E: Program exiting with error com.ibm.websphere.management.exception.AdminException:
ADMU0036E: The Deployment Manager cannot lookup by name
 
Resolving the problem
Change the real host name in the deploymentManager serverindex.xml file. This can be done by using the adminconsole.

Click on System Administration > DeploymenManager > end points >
BOOTSTRAP_ADDRESS. Modify the multi NIC hostname to the real hostname.

Save the changes and stop all servers. Then stop all nodeagents.
Then restart the dmgr and bring back up the nodeagents and servers.
