Registering and Configuring the Oracle ASM Resource Group

Oracle Automatic Storage Management (Oracle ASM) manages the storage that used by the Oracle database. This wizard creates an Oracle ASM instance resource for the Oracle database.

This section contains the following information about registering the Oracle ASM resource group:

Tools for Registering and Configuring the Oracle ASM Resource Group

Oracle Solaris Cluster software provides the following tools for registering and configuring the Oracle ASM resource group in the global cluster or in a zone cluster:

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

The clsetup utility and Oracle Solaris Cluster Manager each provide a wizard for configuring resources for the Oracle ASM resource group. The wizards reduce the possibility of configuration errors that might result from command syntax errors or omissions. These wizards also ensure that all required resources are created and that all required dependencies between resources are set.

Note - Oracle Solaris Cluster Manager and the clsetup utility run only in a voting node of the global cluster.

How to Register and Configure the Oracle ASM Resource Group by Using `clsetup`

When you register and configure the Oracle ASM resource group for a cluster, the Oracle ASM resource group is created.

Perform this procedure from one node only.

Before You Begin

Ensure that Oracle ASM disk groups are configured. For more information, see Using Oracle ASM.

Ensure that you have the following information:

The name of the Oracle ASM home directory.
The list of Oracle ASM systems identifiers (SID).
The name of the file-system mount point to use.
The names of the Oracle ASM disk groups to use.

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 a RAC framework running only in the global cluster. For ongoing administration of a 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 the location of the Oracle RAC cluster and press Return.
- If you select the global cluster option, the clsetup utility displays the list of components of Oracle RAC to configure. Skip to Step 9.
- If you select the zone cluster option, the clsetup utility prompts you to select the required zone cluster. Proceed to Step 8.
Type the option number for the required zone cluster and press Return.
The clsetup utility displays a list of components of Oracle RAC to configure.
Type the option number for Automatic Storage Management (ASM) and press Return.
The clsetup utility displays a list of the cluster nodes to select.
Select the nodes where you require Oracle ASM to run.
- To accept the default selection of all listed nodes in an arbitrary order, type a and press Return.
- To select a subset of the listed nodes, type a comma-separated or space-separated list of the option numbers for the nodes you choose and press Return.
  Ensure that the nodes are listed in the order in which the nodes are to appear in the RAC framework resource group's node list.
- To select all nodes in a particular order, type a comma-separated or space-separated ordered list of the option numbers for the nodes you choose and press Return.
  Ensure that the nodes are listed in the order in which the nodes are to appear in the RAC framework resource group's node list.
If needed to end the selection of nodes, type d and press Return.
The clsetup utility displays a list of Oracle ASM instance resources.
Type the option number that corresponds to the Oracle ASM instance resource to use.
If no Oracle ASM instance resource is available and you are prompted to create a resource, press Return. Skip to Step 14.
To confirm your selection of an Oracle ASM instance resource, type d and press Return.
The clsetup utility displays the selection screen for the Oracle ASM home directory.
Type the option number to choose a listed directory or to specify a directory explicitly and press Return.
The clsetup utility displays a list of Oracle ASM system identifiers (SID) that are discovered in the cluster.
Review the list of SIDs.
- If the list is correct, type d and press Return.
- If the list is not correct, type the option number for the SID to change and press Return.
The clsetup utility displays a list of discovered storage resources.
Review the list of storage resources to manage the file-system mount point where the Oracle ASM home is installed.
- If the list is correct, type d and press Return.
- If no storage resource is listed, type d and press Return.
  The clsetup utility will create a new resource when you complete Oracle ASM configuration.
- If the list is not correct, type the option number for the incorrect storage resource and press Return.
The clsetup utility displays a list of Oracle ASM disk-group resources that manage Oracle ASM disk groups.
If no suitable disk-group resources exist, or if no resource exists for an Oracle ASM disk group that you are using, add a resource to the list.
1. Type y and press Return.
  The clsetup utility discovers Oracle ASM disk groups.
2. Type a comma-separated or space-separated list of the option numbers for the Oracle ASM disk groups to use and press Return.
3. To confirm your selection of disk groups, type d and press Return.
  The clsetup utility returns you to the list of Oracle ASM disk-group resources. The resource that you are creating is added to the list.
Type the option numbers for the resources that you require, if not already selected.
You can select existing resources, resources that are not yet created, or a combination of existing resources and new resources. If you select more than one existing resource, the selected resources must be in the same resource group.
To confirm your selection of resources for Oracle ASM disk groups, type d and press Return.
The clsetup utility displays a list of discovered underlying disk sets or disk groups.
Type a comma-separated list of the option numbers for the global-device paths to use and press Return.
To confirm your selection of global-device paths, type d and press Return.
The clsetup utility displays the names of the Oracle Solaris Cluster objects for Oracle ASM that the utility will create or add to your configuration.
If you need to modify an Oracle Solaris Cluster object, modify the object.
1. Type the option number for the object to modify and press Return.
  The clsetup utility prompts you for the new value.
2. At the prompt, type the new value and press Return.
The clsetup utility returns you to the list of properties that are set for the object.
When you have modified all the Oracle Solaris Cluster objects that you need to change, 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.
