SUNW.rac_svm

, rac_svm

- resource type implementation that represents the Solaris Volume Manager component of Oracle Solaris 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 Oracle Solaris 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:

• Oracle Solaris Cluster Manager

• The clsetup(1CL) utility, specifying the option for configuring Oracle Solaris Cluster Support for Oracle Real Application Clusters

• The following sequence of Oracle Solaris 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. Oracle Solaris 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.

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 Oracle Solaris 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 Oracle Solaris 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 Oracle Solaris 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 Oracle Solaris 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 Oracle Solaris 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 Oracle Solaris 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 Oracle Solaris 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 Oracle Solaris 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 Oracle Solaris 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 Oracle Solaris 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 Oracle Solaris 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
