Solaris 10 and OpenSolaris : Web Based Management tools and Sun Cluster installation

Gurus,

I have several questions :

  1. Does Solaris 10/OpenSolaris has some kind of web based management tools ?
    Currently I am using WebMin. It worked fine, however I am very curious to use
    the tools provided by Sun Microsystem.
    Please advise for package name and how to activate.

  2. I also found out that ZFS also has the same Web Based Management tools.
    As the documentation said, it can be accessed on http://localhost:6789
    As checked, I suspect the package for this feature is not installed.
    Please advise for package name and how to activate.

  3. I tried to install both Sun Cluster 3.2 and Open HA Cluster from source.
    For Sun Cluster 3.2, there were a long error generated by the java program
    when installed. Sorry, I havent capture the screen when the error occured.
    For Open HA cluster, compilation also failed.
    FYI: I used OpenSolaris 2008.11 version.
    Please advise for websites that can provide step-by-step procedure to
    install these cluster software.

Many thanks in advance.
