After upgrading the version from 11.13 to 11.16 getting error

[JUGAL KISHORE MAHESHWAR]

I have upgraded the Service Guard version from 11.13 to 11.16 , after upgrade I am getting following error while running below commands.

root@iran:>cmviewconf
cmviewconf: Either binary file does not exist, or the user doesn't
have access to view the cluster configuration.

root@iran:>cmviewcl
Error: Permission denied to 127.0.0.1
cmviewcl : Cannot view the cluster configuration.
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.

Check the permission of the /.rhosts file on the node on which you are running the commands.

It should be like
-rw------- 1 root sys 229 Feb 11 21:04 .rhosts
