In a previous version of the cluster software, the following preregistered resource types were enhanced:
SUNW.LogicalHostname, which represents a logical hostname
SUNW.SharedAddress, which represents a shared address
The purpose of these enhancements was to enable you to modify logical hostname resources and shared address resources to bypass name services for name resolution.
Upgrade these resource types if all conditions in the following list apply:
You are upgrading from an earlier version of Oracle Solaris Cluster
You need to use the new features of the resource types
For general instructions that explain how to upgrade a resource type, see Upgrading a Resource Type. The information that you need to complete the upgrade of the preregistered resource types is provided in the subsections that follow.
