The SUNW.vucmm_framework resource type represents the framework that enables different clustered volume managers in a Sun Cluster configuration. This resource type enables you to monitor the status of this framework.
The SUNW.vucmm_framework resource type is a single instance resource type. You can create only one resource of this type in the cluster.
To register this resource type and create instances of this resource type, use the following means:
To register this resource type, use the clresourcetype(1CL) command.
To create instances of this resource type, use the clresource(1CL) command.
When a resource of this type is brought offline on a node, the transition from the online state to the offline state requires a finite time to complete. During the transition to the offline state, the resource continues to participate in reconfiguration processes. However, when the resource is offline on a node, changes to resource properties are not effective on the node until the resource is brought back online. Sun Cluster software displays a warning message to this effect when a resource of this type is disabled.
The transition to the unmanaged state of a resource group that contains a resource of this type requires a finite time to complete. During the transition to the unmanaged state, the framework continues to participate in framework reconfiguration processes. However, when the resource group is unmanaged, changes to resource properties are not effective on the node. To stop the framework, you must reboot the node.
The extension properties of the SUNW.vucmm_framework resource type are as follows:
Type integer; minimum 100; maximum 99999; defaults to 325. This property specifies the timeout (in seconds) for the reservation step of a reconfiguration of the framework. You can modify this property at any time.
This example registers the SUNW.vucmm_framework resource type and creates an instance of the SUNW.vucmm_framework resource type named vucmm_framework-rs. The example assumes that a resource group named vucmm_framework-rg has been created.
phys-host-sc1# clresourcetype register SUNW.vucmm_framework phys-host-sc1# clresource create -g vucmm_framework-rg \ -t SUNW.vucmm_framework vucmm_framework-rs |
This example sets the timeout for the reservation step of a reconfiguration of the framework to 350 seconds. The example assumes that a resource of type SUNW.vucmm_framework that is named vucmm_framework-rs has been created.
phys-host-sc1# clresource set -p reservation_timeout=350 vucmm_framework-rs |

Sun Cluster Data Services Planning and Administration Guide for Solaris OS
On the Solaris 10 OS, if you are using only Oracle RAC, you can optionally configure an additional resource group that uses the SUNW.vucmm_framework resource type, in addition to the resource group that uses the SUNW.rac_framework resource type. If you use this SUNW.vucmm_framework resource group, it must include the VUCMM version of any storage resource types that you need, SUNW.vucmm_svm and SUNW.vucmm_cvm, instead of using the SUNW.rac_svmand SUNW.rac_cvm resource types in the SUNW.vucmm_framework resource group. You can then use the SUNW.vucmm_framework resource group to configure other data services.
If you configure any applications other than Oracle RAC to use a Sun QFS shared file system, you must use the SUNW.vucmm_framework resource group to contain all storage resource types that are used by the applications, including Oracle RAC. However, to support Oracle RAC you still need the separate resource group that is based on the SUNW.rac_framework resource type but does not contain the SUNW.rac_svm or SUNW.rac_cvm resource type.
At some future time you might decide to configure other data services to use a Sun QFS shared file system. To avoid the possible need to migrate an Oracle RAC configuration to accommodate such use, configure Oracle RAC to use a SUNW.vucmm_framework resource group that includes any needed VUCMM storage resource types.
