NAME

SUNW.rac_svm, rac_svm – resource type implementation that represents the Solaris Volume Manager component of Sun Cluster Support for Oracle Real Application Clusters (RAC)

Description

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:
1. To register this resource type, use the clresourcetype(1CL) command.
2. 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 extension properties of the SUNW.rac_svm resource type are as follows.

debug_level: 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.
svm_abort_step_timeout: 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.
svm_return_step_timeout: 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.
svm_start_step_timeout: 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.
svm_step1_timeout: 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.
svm_step2_timeout: 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.
svm_step3_timeout: 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.
svm_step4_timeout: 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.
svm_stop_step_timeout: 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.

Examples

Example 1 Creating a `rac_svm` Resource

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

Example 2 Changing a Property of a `rac_svm` Resource

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
