Discovering systems with multiple IP addresses on SIM 5.0

[Ben Lye]

I run several Linux servers with more than one IP address. Each IP address has a valid DNS entry for the server, and each IP address is in subnets that are configured for automatic discovery.

How do I get SIM 5.0 to identify the IP addresses as belonging to one system, rather than creating orphan systems?

Strangely, it has worked automatically for one server, but has failed for three others. All the systems are running the latest agents.

I have tried deleting all the systems, and using manual discovery to add them (adding each IP address), but I end up with three correctly identifed systems, which the automatic discovery then reverts back to orphans.

I want one system, with three IP addresses, how can I do it?

If the SNMP community strings are properly configured and Insight Management Agents/Server Agents are running properly on the managed nodes then running a Fresh automatic dicovery (after deleting the orphans...) should associate all the IP addresses to the correct server.

Hi,

I've tried repeated Automatic Discoveries, with the same result - the orphas just stay there.

Obviously as the IP addresses all point to the same machine the SNMP/agent settings are all the same.

When you browse to the SMH (NIC Agent)of the managed node, are you able to see all the IP addresses listed in there?

No, each orphan system just lists the IP address it was discovered with, although sometimes they don't list an IP address at all.

The one system that got discovered correctly shows all three IP address.

I'm experimenting with SIM 5.2 and came across the same issue. Actually my goal was to make SIM think that a system has two IP addresses when in fact the second IP address belongs to a different machine. This is how I did it:

1) Create an XML file like the one in the example attached (replace "example" with the system name as it appears in SIM) and put all IP addresses that you want for this system in the file.

2) Run "mxnode -m -f example.xml" in a command window.

3) Wait about a minute before the changes appear in the SIM web interface.
