The SUNW.rac_svm resource type represents the Solaris Volume Manager for Sun Cluster component of the Sun Cluster framework for Oracle RAC.
Instances of the SUNW.rac_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.rac_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 one of the following means:
Sun Cluster Manager
The clsetup(1CL) utility, specifying the option for configuring Sun Cluster Support for Oracle Real Application Clusters
The following sequence of Sun Cluster maintenance commands:
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 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 Oracle RAC 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 Oracle RAC framework, the node must be rebooted.
The SUNW.rac_svm resource type is only valid in a resource group that uses the SUNW.rac_framework resource type. Do not use this resource type in a SUNW.vucmm_framework resource group.
The extension properties of the SUNW.rac_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 Sun Cluster framework for Oracle RAC. 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 Sun Cluster Support for Oracle RAC. 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 Sun Cluster Support for Oracle RAC. 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 Sun Cluster Support for Oracle RAC. 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 Sun Cluster Support for Oracle RAC. 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 Sun Cluster Support for Oracle RAC. 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 Sun Cluster Support for Oracle RAC. 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 Sun Cluster Support for Oracle RAC. 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 Sun Cluster Support for Oracle RAC. You can modify this property at any time.
This example registers the SUNW.rac_svm resource type and creates an instance of the SUNW.rac_svm resource type that is named rac_svm-rs. The example assumes that the following Sun Cluster objects have been created:
A resource group that is named rac-framework-rg
A resource of type SUNW.rac_framework that is named rac_framework-rs
phys-schost-1# clresourcetype register SUNW.rac_svm phys-schost-1# clresource create -g rac-framework-rg \ -t SUNW.rac_svm \-p resource_dependencies=rac_framework-rs rac_svm-rs |
This example sets the timeout for step 4 of a reconfiguration of the Solaris Volume Manager for Sun Cluster component of Sun Cluster Support for Oracle RAC to 300 seconds. The example assumes that an instance of the SUNW.rac_svm resource type named rac_svm-rs has been created.
phys-schost-1# clresource set \ -p svm_step4_timeout=300 rac_svm-rs |
For examples to create a new SUNW.vucmm_svm resource, see SUNW.vucmm_svm(5).

Sun Cluster Data Service for Oracle RAC 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.
