How to Modify an Extension Property That Is Tunable Only When a Resource Is Disabled

Restrictions apply to the circumstances in which you can modify an extension property that is tunable only when a resource is disabled. Those circumstances depend on the resource type as follows:

• SUNW.rac_udlm – Only when the Oracle UDLM is not running on any cluster node

• SUNW.rac_cvm – Only when VxVM is not running in cluster mode on any cluster node

This procedure provides the long forms of the Sun Cluster maintenance commands. Most commands also have short forms. Except for the forms of the command names, the commands are identical. For a list of the commands and their short forms, see Appendix A, Sun Cluster Object-Oriented Commands, in Sun Cluster Data Services Planning and Administration Guide for Solaris OS.

1. Disable each resource that the RAC framework resource group contains and bring the RAC framework resource group into the UNMANAGED state.

   Disable the instance of the SUNW.rac_framework resource only after you have disabled all other resources that the RAC framework resource group contains. The other resources in the RAC framework resource group depend on the SUNW.rac_framework resource.

   For detailed instructions, see Disabling Resources and Moving Their Resource Group Into the UNMANAGED State in Sun Cluster Data Services Planning and Administration Guide for Solaris OS.

2. Reboot all the nodes that are in the node list of the RAC framework resource group.

3. Use the clresource command to set the property to its new value.

   # clresource set -p property=value resource

   property

   Specifies the name of the property that you are changing.

   value

   The new value of the property.

   resource

   Specifies the name of the resource for which you are modifying an extension property. If this resource was created by using the clsetup utility, the name depends on the resource type, as shown in Automatically Generated Names for Sun Cluster Objects.

4. Bring the RAC framework resource group and its resources online.

   # clresourcegroup online resource-group

   resource-group

   Specifies the name of the RAC framework resource group that is to be moved to the MANAGED state and brought online. If this resource group was created by using the clsetup utility, the name of the resource group is rac-framework-rg.
