Solaris 11 Syntax to Update Client

What is the correct syntax to use to update the NB client on SunOS 5.11?

I tried Solaris Solaris11 and got the error below...

Cannot update client servername
        Invalid hardware type "Solaris" and/or operating system "Solaris11"
        or client binaries are not installed on the server.

When I tried it with Solaris Solaris10 I got this errorr...

ERROR:   Detected an attempt to install incorrect platform and/or
         operating system and version client binaries on servername.
