zcs clustering error

[riju123]

Hi,
I'm following Zimbra multi-node cluster guide for setting up zcs cluster in my work environment.I'm using CentOS5.5 OS and ZCS-NE-6.0.8 for the installation.I have installed Cluster packages on the server.When I started RHEL cluster suite deamons,I'm getting following error-

[root@mbx2 opt]# /etc/init.d/cman start
Starting cluster:
Loading modules... done
Mounting configfs... done
Starting ccsd... done
Starting cman... failed
cman not started: CCS does not have a nodeid for this node, run 'ccs_tool addnodeids' to fix /usr/sbin/cman_tool: aisexec daemon didn't start
[FAILED]
Before this step,everything was successfully completed.

Appreciate if anyone could help me out to resolve this error.
