MC/ServiceGuard Problem: cmcld

Hi All,

I have two N class systems running MC/ServiceGuard and one node is up and running and I can't get the other node to join the cluster. Here is the output from running cmrunnode and syslog.log. Any help would be appreciated.

cmrunnode : Waiting for cluster to form...........
cmrunnode : Node systemname unable to join cluster. Check syslog
on that node for information.

Output from syslog:

Mike, You have a network disconnection problem. Trouble shoot on the cable connections.

Re: MC/ServiceGuard Problem: cmcld


From the syslog you supplied, cmcld is complaining about the loss of IP address Is this configured as a heartbeat address on the server that fails to join the cluster?

If so, have you changed anything regarding the network configuration such that this address is no longer configured?

Check your serviceguard configuration file for HEARTBEAT and /etc/rc.config.d/netconf for your network settings. You can also run netstat -in to check how your what IP addresses are configured


Re: MC/ServiceGuard Problem: cmcld

Sounds like you have a configuration problem.
There are two useful commands to help here.
1. do a cmquerycl -v -C /tmp/testascii -n -n and see what the cluster services actually see out there. Also sompare this with your cluster ascii file.

2. use the cmscancl command, which will output a file to /tmp/scancl.out, and then review this file for info on the networks, and what is in the cluster binary.

3. you should check and confirm all of your network configurations for inconsistencies or changes.

Re: MC/ServiceGuard Problem: cmcld

Thank you all. You pointed me in the right direction. Some how someone changed the IP address on one of the nodes lan cards. I am the only admin but a few developers have some root capability. Will have to go to the logs and find out who did that.

All is working fine now.
