How to Modify a Logical Hostname Resource or a Shared Address Resource

By default, logical hostname resources and shared address resources use name services for name resolution. You might configure a cluster to use a name service that is running on the same cluster. During the failover of a logical hostname resource or a shared address resource, a name service that is running on the cluster might also be failing over. If the logical hostname resource or the shared address resource uses the name service that is failing over, the resource fails to fail over.


Note -  Configuring a cluster to use a name server that is running on the same cluster might impair the availability of other services on the cluster.

To prevent such a failure to fail over, modify the logical hostname resource or the shared address resource to bypass name services. To modify the resource to bypass name services, set the CheckNameService extension property of the resource to false. You can modify the CheckNameService property at any time.


Note -  You can also use the Oracle Solaris Cluster Manager browser interface to edit logical hostname or shared address resources. For Oracle Solaris Cluster Manager log-in instructions, see How to Access Oracle Solaris Cluster Manager in Administering an Oracle Solaris Cluster 4.4 Configuration.

Before You Begin

If your version of the resource type is earlier than 2, you must upgrade the resource type before you attempt to modify the resource. For more information, see Upgrading a Preregistered Resource Type.

  1. On a cluster member, assume the root role that provides solaris.cluster.modify RBAC authorization.
  2. Change the resource property.
    # clresource set -p CheckNameService=false resource
    -p CheckNameService=false

    Sets the CheckNameService extension property of the resource to false.

    resource

    Specifies the name of the logical hostname resource or shared address resource that you are modifying.
