Hi Hung-Sheng, In discussing my problem with various engineers, this mistake keeps coming up. We plan on running the Sunray server software in the global zones of each cluster member, in a non-clustered configuration. We only want to cluster the Solaris 10 branded zones/containers, not the Sunray server software. Sorry if I hadn't explained that clearly.
