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

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 scrgadm utility to set the property to its new value.

   # scrgadm -c -j resource -x property=value

   -j resource

   Specifies the name of the resource for which you are modifying an extension property. If this resource was created by using the scsetup utility, the name depends on the resource type as shown in Table 2–3.

   property

   Specifies the name of the extension property that you are changing.

   value

   The new value of the extension property.

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

   # scswitch -Z -g resource-group

   -Z

   Enables the resource and monitor, moves the resource group to the MANAGED state, and brings the resource group online.

   -g 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 scsetup utility, the name of the resource group is rac-framework-rg.
