By default, when you install opensaf, the default value in /etc/opensaf/node_name will be the output of the command 'hostname -s'.
The value in /etc/opensaf/node_name represents the rdn of the CLM node name.

[Mathi]
The first column is node_type, second column contains rdn value of AMF node name, and The 3rd column represents the rdn value of the CLM node name.
Typically the CLM node name would be the hostname. 

The nodes.cfg is generated with default values set to SC-1, SC-2 etc. **This value should match The value that you specify in /etc/opensaf/node_name**. 

In your case, if you  want safNode=WR20-64_25,safCluster=myClmCluster as your CLM node name, And if you want the AMF node name as safAmfNode= WR20-64_25,safAmfCluster=myAmfCluster, THEN You should configure /etc/opensaf/node_name with the value WR20-64_25 And your nodes.cfg should look like For eg:- 

SC WR20-64_25 WR20-64_25
