cfgadm: Configuration administration not supported                  

This error will occur if the user does not have the minimum required version of Solaris OS installed.

The minimum supported configuration is Solaris 8 2/02, with the recommended patch cluster as per Infodoc 43382

To determine which version of Solaris you are running, view the /etc/release file. It should look similar to this:

# cat /etc/release
                       Solaris 8 2/02 s28s_u7wos_08a SPARC
