Hi all,

@

Pre-Requisites Test(s) failed with the following message(s) :

Older version "1.0.9-60.el5.x86_64" of "nfs-utils" is installed, "1.0.9-60.0.2" or higher is required

Short hostname demo appears in /etc/hosts more than once

This systems fully qualified domain name demo.rsa_lg.local is not valid

Forward (A record) DNS record is not correct or non-existent ;

nsf-utils issue is fixed but I can not seem to solve the two following problem:

@

This systems fully qualified domain name demo.rsa_lg.local is not valid

Forward (A record) DNS record is not correct or non-existent ;

The Configuration of  /etc/hosts worked with RSA via L&G 7.0.

Any ideas?

Thanks by advance.
