sujit kumar singh — Wed, 23 Dec 2009 09:34:15 GMT

the location of the file is

/etc/cmcluster/nodelist

and the entries are:

You may want to add a comment such as the following at the top of the file:
###########################################################
# Do not edit this file!
# Serviceguard uses this file only to authorize access to an
# unconfigured node. Once the node is configured,
# Serviceguard will not consult this file.
###########################################################
The format for entries in cmclnodelist is as follows:
# For example: gryf root #cluster1, node1 sly root #cluster1, node2 bit root #cluster1, node3 This example grants root access to the node on which this cmclnodelist file resides to root users on the nodes gryf, sly, and bit. or you can try setting /.rhosts or /etc/hosts.equiv regards sujit regards sujit

The format for /etc/cmcluster/cmclnodelist is the same as that of .rhosts
You need to make sure all relevant entries are inserted to allow this to work.
Take a read of:

and

I get the same error again, where else do I need to make changes please

Re: Node is refusing Serviceguard communication

firstly, you have the wrong filename, it should be cmclnodelist.
You also need to make sure that this file is duplicated onto the other node

Secondly, start of simple by just inclduing your local host to see if that works, then add in the second node.

you also need to make sure that the identd entry in /etc/inetd.conf is not commented out

and then when I do cmviewcl I get the following error

[rx86-1p0]/
# cmviewcl
cmviewcl: Cannot view the cluster configuration: No such file or directory.
Either this node is not configured in a cluster, user doesn't have
access to view the cluster configuration, or there is some obstacle
to viewing the configuration. Check the syslog file for more information.
For a list of possible causes, see the Serviceguard manual for cmviewcl.
