The SUNW.vucmm_svm resource type represents the Solaris Volume Manager for Sun Cluster component of the Sun Cluster volume manager reconfiguration framework.
Instances of the SUNW.vucmm_svm resource type hold Solaris Volume Manager for Sun Cluster component configuration parameters. Instances of this type also show the status of a reconfiguration of the Solaris Volume Manager for Sun Cluster component.
The SUNW.vucmm_svm resource type is a single-instance resource type. Only one resource of this type may be created 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.
The SUNW.vucmm_svm resource type is only valid in a resource group that uses the SUNW.vucmm_framework resource type. Do not use this resource type in a SUNW.rac_framework resource group.
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 volume manager reconfiguration 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 volume manager reconfiguration framework, you must reboot the node.
The extension properties of the SUNW.vucmm_svm resource type are as follows.
Type integer; minimum 0; maximum 10; defaults to 1. This property specifies the debug level for the Solaris Volume Manager for Sun Cluster module of the volume manager reconfiguration framework. When the debug level is increased, more messages are written to the log files during reconfiguration. You can modify this property at any time.
Type integer; minimum 30; maximum 99999; defaults to 120. This property specifies the timeout (in seconds) for the abort step of a reconfiguration of the Solaris Volume Manager for Sun Cluster module of the volume manager reconfiguration framework. You can modify this property at any time.
Type integer; minimum 30; maximum 99999; defaults to 120. This property specifies the timeout (in seconds) for the return step of a reconfiguration of the Solaris Volume Manager for Sun Cluster module of the volume manager reconfiguration framework. You can modify this property at any time.
Type integer; minimum 30; maximum 99999; defaults to 120. This property specifies the timeout (in seconds) for the start step of a reconfiguration of the Solaris Volume Manager for Sun Cluster module of the volume manager reconfiguration framework. You can modify this property at any time.
Type integer; minimum 30; maximum 99999; defaults to 120. This property specifies the timeout (in seconds) for step 1 of a reconfiguration of the Solaris Volume Manager for Sun Cluster module of the volume manager reconfiguration framework. You can modify this property at any time.
Type integer; minimum 30; maximum 99999; defaults to 120. This property specifies the timeout (in seconds) for step 2 of a reconfiguration of the Solaris Volume Manager for Sun Cluster module of the volume manager reconfiguration framework. You can modify this property at any time.
Type integer; minimum 30; maximum 99999; defaults to 120. This property specifies the timeout (in seconds) for step 3 of a reconfiguration of the Solaris Volume Manager for Sun Cluster module of the volume manager reconfiguration framework. You can modify this property at any time.
Type integer; minimum 100; maximum 99999; defaults to 120. This property specifies the timeout (in seconds) for step 4 of a reconfiguration of the Solaris Volume Manager for Sun Cluster module of the volume manager reconfiguration framework. You can modify this property at any time.
Type integer; minimum 30; maximum 99999; defaults to 120. This property specifies the timeout (in seconds) for the stop step of a reconfiguration of the Solaris Volume Manager for Sun Cluster module of the volume manager reconfiguration framework. You can modify this property at any time.
This example registers the SUNW.vucmm_svm resource type and creates an instance of the SUNW.vucmm_svm resource type that is named vucmm_svm-rs. The example assumes that the following Sun Cluster objects have been created:
A resource group that is named vucmm_framework-rg
A resource of type SUNW.vucmm_framework that is named vucmm_framework-rs
phys-schost-1# clresourcetype register SUNW.vucmm_svm phys-schost-1# clresource create -g vucmm_framework-rg \ -t SUNW.vucmm_svm \ -p resource_dependencies=vucmm_framework-rs vucmm_svm-rs |
This example sets the timeout for step 4 of a reconfiguration of the Solaris Volume Manager for Sun Cluster component of the volume manager reconfiguration framework to 300 seconds. The example assumes that an instance of the SUNW.vucmm_svm resource type named vucmm_svm-rs has been created.
phys-schost-1# clresource set \ -p svm_step4_timeout=300 vucmm_svm-rs |

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.
