Registering and Configuring the Multiple-Owner Volume-Manager Framework Resource Group

Registering and configuring the multiple-owner volume-manager framework resource group enables Oracle RAC to manage multiple-owner volume-manager resources with Oracle Solaris Cluster software.

The multiple-owner volume manager framework resource in the global-cluster voting node supports any volume manager used by Oracle RAC anywhere on the machine, including the global cluster and all zone clusters.

This section contains the following information about registering the multiple-owner volume-manager framework resource group:

Tools for Registering and Configuring the Multiple-Owner Volume-Manager Framework Resource Group

Oracle Solaris Cluster software provides the following tools for registering and configuring the multiple-owner volume manager framework resource group in the global cluster or in a zone cluster:

The clsetup utility. For more information, see How to Register and Configure the Multiple-Owner Volume-Manager Framework Resource Group by Using clsetup.
Oracle Solaris Cluster maintenance commands. For more information, see Appendix D, Command-Line Alternatives.

The clsetup utility provides a wizard for configuring resources for the multiple-owner volume manager framework resource group. The wizard reduces the possibility of configuration errors that might result from command syntax errors or omissions. This wizard also ensures that all required resources are created and that all required dependencies between resources are set.

Note - The clsetup utility runs only in a voting node of the global cluster.

How to Register and Configure the Multiple-Owner Volume-Manager Framework Resource Group by Using `clsetup`

When you register and configure the multiple-owner volume manager framework resource group for a cluster, the multiple-owner volume manager framework resource group is created.

Perform this procedure during your initial setup of Support for Oracle RAC. Perform this procedure from one node only.

Before You Begin

Ensure that all storage management software that you intend to use is installed and configured on all nodes where Oracle RAC is to run.
Ensure that you have the list of storage management schemes that you are using for Oracle files.

Become superuser on any cluster node.
Start the clsetup utility.
```
# clsetup
```
The clsetup main menu is displayed.
Type the option number for Data Services and press Return.
The Data Services menu is displayed.
Type the option number for Oracle Real Application Clusters and press Return.
The clsetup utility displays information about Support for Oracle RAC.
Press Return to continue.
The clsetup utility prompts you to select whether you are performing the initial configuration of Support for Oracle RAC or administering an existing configuration.

Note - The clsetup utility currently allows ongoing administration of an Oracle RAC framework running only in the global cluster. For ongoing administration of an Oracle RAC framework configured in a zone cluster, use instead the Oracle Solaris Cluster maintenance commands.
Type the option number for Oracle RAC Create Configuration and press Return.
The clsetup utility prompts you to select the Oracle RAC cluster location. This location can be the global cluster or a zone cluster.
Type the option number for Global Cluster and press Return.
Note - Configure a multiple-owner volume-manager framework resource group only in the global cluster.

The clsetup utility displays the list of components of Oracle RAC to configure.
Type the option number for Multiple-Owner Volume-Manager Framework Resource Group and press Return.
The clsetup utility displays an overview about this task.
Press Return to continue.
The clsetup utility prompts you to select the multiple-owner volume managers to use. Only installed volume managers are listed.
Type the option numbers for the multiple-owner volume managers to use and press Return.
To confirm your selection of multiple-owner volume managers, type d and press Return.
The clsetup utility displays the names of the Oracle Solaris Cluster objects that the utility will create.
If you require a different name for any Oracle Solaris Cluster objects, change the name.
1. Type the option number for the name to change and press Return.
  The clsetup utility displays a screen where you can specify the new name.
2. At the New Value prompt, type the new name and press Return.
The clsetup utility returns you to the list of the names of the Oracle Solaris Cluster objects that the utility will create.

Note - If, after you configure the multiple-owner volume manager framework resource group, you again run this wizard to configure another volume manager, the names of the multiple-owner volume manager framework resource group and its existing resources are not available to rename.
To confirm your selection of Oracle Solaris Cluster object names, type d and press Return.
The clsetup utility displays information about the Oracle Solaris Cluster configuration that the utility will create.
To create the configuration, type c and Press Return.
The clsetup utility displays a progress message to indicate that the utility is running commands to create the configuration. When configuration is complete, the clsetup utility displays the commands that the utility ran to create the configuration.
Press Return to continue.
The clsetup utility returns you to the list of options for configuring Support for Oracle RAC.
(Optional) Type q and press Return repeatedly until you quit the clsetup utility.
If you prefer, you can leave the clsetup utility running while you perform other required tasks before using the utility again. If you choose to quit clsetup, the utility recognizes your existing multiple-owner volume-manager framework resource group when you restart the utility.
Determine whether the multiple-owner volume-manager framework resource group and its resources are online.
Use the clresourcegroup(1CL) utility for this purpose. By default, the clsetup utility assigns the name vucmm_framework_rg to the multiple-owner volume-manager framework resource group.
```
# clresourcegroup status vucmm_framework_rg
```
If the multiple-owner volume-manager framework resource group and its resources are not online, bring them online.
```
# clresourcegroup online vucmm_framework_rg
```

Resource Configuration

The following table lists the default resource configuration that the clsetup utility creates when you complete this task.

Resource Name, Resource Type, and Resource Group	Dependencies	Description
Resource type: `SUNW.vucmm_framework` Resource name: `vucmm_framework_rs` Resource group: `vucmm_framework_rg`	None.	Multiple-owner volume-manager framework resource.
Resource type: `SUNW.vucmm_svm` Resource name: `vucmm_svm_rs` Resource group: `vucmm_framework_rg`	Strong dependency on the multiple-owner volume-manager framework resource.	Solaris Volume Manager for Sun Cluster resource. Created only if Solaris Volume Manager for Sun Cluster was selected.
