"Error: Node app6 is refusing Serviceguard communication." from cmcheckconf

Steven Farnsworth — Mon, 26 Feb 2007 04:45:18 GMT

We are using the server app6 as our master for configuring the cluster, and are copying a configuration we have working in a separate cluster.

These are all running Red Hat Linux RHEL3

We have verified that cmclnodelist contains "app6 root"

We have also verified that "ping app6" works from app6 itself.

What should we be looking at?

I would say your (x)inetd.conf & services files.. do they have the necessary ServiceGuard entries ?

Also, as described in http://forums1.itrc.hp.com/service/forums/questionanswer.do?threadId=906175 , a running identd would also be important.

Cheers,

This may be in teh link that Wouter sent but just in case:

If you get an error message when doing a cmquerycl, cmapplyconf, or cmcheckconf indicating the Serviceguard cannot communicate with a node.

1. Usually this means that the firewall is set up incorrectly. Try turning off the firewall
2. Also, identd may not have started. "identd" is the service associated with pidentd (see #2). Make sure this is set to start automatically.
3. Check that the file cmclnodelist has been created and is set up correctly.
4. After you make all of the changes, reboot both nodes.

To debug cmnodelist - use the "+" as described int eh manual.
