The following Solaris OS features are not supported in a Sun Cluster configuration:
Sun Cluster 3.1 8/05 software does not support non-global zones. All Sun Cluster software and software that is managed by the cluster must be installed only on the global zone of the node. Do not install cluster-related software on a non-global zone. In addition, all cluster-related software must be installed in a way that prevents propagation to a non-global zone that is later created on a cluster node. For more information, see Adding a Package to the Global Zone Only in System Administration Guide: Solaris Containers-Resource Management and Solaris Zones.
Solaris interface groups are not supported in a Sun Cluster configuration. The Solaris interface groups feature is disabled by default during Solaris software installation. Do not re-enable Solaris interface groups. See the ifconfig(1M) man page for more information about Solaris interface groups.
Sun Cluster software does not support filtering with Solaris IP Filter. The use of the STREAMS autopush(1M) mechanism by Solaris IP Filter conflicts with Sun Cluster software's use of the mechanism.
