In Sun Cluster 3.1 9/04, the following preregistered resource types are enhanced:
SUNW.LogicalHostname, which represents a logical hostname
SUNW.SharedAddress, which represents a shared address
The purpose of these enhancements is 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 Sun 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.
The relationship between the version of each preregistered resource type and the release of Sun Cluster is shown in the following table. The release of Sun Cluster indicates the release in which the version of the resource type was introduced.
Resource Type |
Resource Type Version |
Sun ClusterRelease |
---|---|---|
SUNW.LogicalHostname
|
1.0 |
3.0 |
2 |
3.1 9/04 |
|
SUNW.SharedAddress
|
1.0 |
3.0 |
2 |
3.1 9/04 |
To determine the version of the resource type that is registered, use one command from the following list:
clresourcetype list
clresourcetype list -v
This example shows the command for registering version 2 of the SUNW.LogicalHostname resource type during an upgrade.
# clresourcetype register SUNW.LogicalHostname:2 |
The information that you need to migrate an instance of a preregistered resource type is as follows:
You can perform the migration at any time.
If you need to use the new features of the preregistered resource type, the required value of the Type_version property is 2.
If you are modifying the resource to bypass name services, set the CheckNameService extension property of the resource to false.
This example shows the command for migrating the logical hostname resource lhostrs. As a result of the migration, the resource is modified to bypass name services for name resolution.
# clresource set -p CheckNameService=false -p Type_version=2 lhostrs |
