- resource type implementation for the Oracle Solaris Cluster volume manager reconfiguration framework
The SUNW.vucmm_framework resource type represents the framework that enables different clustered volume managers in an Oracle Solaris 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. Oracle Solaris 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.
Example 1 Creating a vucmm_framework Resource
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
Example 2 Changing a Property of a vucmm_framework Resource
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
