The resource types SUNW.LogicalHostname and SUNW.SharedAddress are preregistered. All of the logical hostname and shared address resources use these resource types. You never need to register these two resource types, but you might inadvertently delete them. If you have deleted resource types inadvertently, use the following procedure to reregister them.
If you are upgrading a preregistered resource type, follow the instructions in Upgrading a Preregistered Resource Type to register the new resource type version.
Perform this procedure from any cluster node.
Reregister the resource type.
# scrgadm -a -t SUNW.resource-type
