Registering and Configuring Storage Resources for Oracle Files

Storage resources provide fault monitoring and automatic fault recovery for global device groups and file systems.

If you are using global device groups or shared file systems for Oracle files, configure storage resources to manage the availability of the storage on which the Oracle software depends.

Configure the following types of storage resources:

Global device groups:
- Solaris Volume Manager for Sun Cluster multi-owner disk sets
Shared file systems:
- A file system on a qualified NAS device with Oracle RAC:
  - Oracle's Sun ZFS Storage Appliance NAS device
  Note - You can configure a NAS NFS in a zone cluster with the existing tools. See Tasks for Configuring Qualified NAS Devices for Oracle Files.

This section contains the following information about registering and configuring storage resources for Oracle files:

Tools for Registering and Configuring Storage Resources for Oracle Files

Oracle Solaris Cluster provides the following tools for registering and configuring storage resources for Oracle files in a global cluster or a zone cluster:

The clsetup(1CL) utility. For more information, see How to Register and Configure Storage Resources for Oracle Files by Using clsetup.
Oracle Solaris Cluster maintenance commands. For more information, see Creating Storage Management Resources by Using Oracle Solaris Cluster Maintenance Commands.

The clsetup utility provides a wizard for configuring storage resources for Oracle files. 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.

How to Register and Configure Storage Resources for Oracle Files by Using `clsetup`

Perform this procedure from only one node of the cluster.

Before You Begin

Ensure that the following prerequisites are met:

The Oracle RAC framework resource group is created and is online. For more information, see Registering and Configuring the Oracle RAC Framework Resource Group.
The multiple-owner volume-manager framework resource group is created and is online. For more information, see Registering and Configuring the Multiple-Owner Volume-Manager Framework Resource Group.

Caution - Do not attempt to manually create the /var/run/nodelist file. Doing so can put the cluster at risk of a cluster-wide panic.
Required volumes, global device groups, and file systems are created. For more information, see the following sections:
- Installing Storage Management Software With Support for Oracle RAC
- Creating a Global Device Group for the Oracle RAC Database
Required file systems are mounted.

Ensure that you have the following information:

The name of each scalable device group that you are using for Oracle files, if any
The mount point of each shared file system that you are using for Oracle files, if any

On one node of the cluster, become superuser.
Start the clsetup utility.

If you are prompted for resources for scalable device groups, omit this step.
If you are prompted to select a Storage Management Scheme for your Oracle files, select the appropriate scheme.
- NAS Device
If no suitable resources exist, or if no resource exists for a device group that you are using, add a resource to the list.
The clsetup utility displays a list of the resources for scalable device groups that are configured on the cluster. If no suitable resources exist, this list is empty.
If resources exist for all the device groups that you are using, omit this step.
For each resource that you are adding, perform the following steps:
1. Press Return.
  The clsetup utility displays a list of the scalable device groups that are configured on the cluster.
2. Type the option number for the device group to use and press Return.
  Once you select the device group, you can either select the entire disk group or choose to specify logical devices, or disks, in the disk group.
3. Choose whether you want to specify logical devices.
  - To specify logical devices, type yes. Proceed to Step d.
  - To select the entire disk group, type no. Skip to Step e.
4. Type a comma-separated list of numbers that corresponds to the logical devices or disks you choose or type a for all.
  The clsetup utility returns you to the list of resources for scalable device groups that are configured on the cluster.
5. To confirm your selection of device groups, type d and press Return.
  The clsetup utility returns you to the list of the resources for scalable device groups that are configured on the cluster. The resource that you are creating is added to the list.
Type the numbers that correspond to 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 device groups, type d and press Return.
The clsetup utility displays a list of the resources for shared file-system mount points that are configured on the cluster. If no suitable resources exist, this list is empty.
If no suitable resources exist, or if no resource exists for a file-system mount point that you are using, add a resource to the list.
If resources exist for all the file-system mount points that you are using, omit this step.
For each resource that you are adding, perform the following steps:
1. Press Return.
  The clsetup utility displays a list of the shared file systems that are configured on the cluster.
2. Type a comma-separated or space-separated list of numbers that correspond to the file systems that you are using for Oracle files and press Return.
3. To confirm your selection of file systems, type d and press Return.

The clsetup utility displays information about the Oracle RAC framework resource group for which storage resources will be configured.
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 Oracle RAC framework resource group when you restart the utility.
Determine whether the resource groups that the wizard created are online.
```
# clresourcegroup status
```
If a resource group that the wizard created is not online, bring the resource group online.
For each resource group that you are bringing online, type the following command:
```
# clresourcegroup online -emM rac-storage-rg
```
rac-storage-rg

Specifies the name of the resource group that you are bringing online.

Resource Configuration

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

Resource Type, Resource Name, and Resource Group	Dependencies	Description
Resource type: `SUNW.ScalDeviceGroup` Resource name: `scaldg-name-rs`, where `dg-name` is the name of the device group that the resource represents Resource group: `scaldg-rg`	Strong dependency on the resource in the multiple-owner volume-manager framework resource group for the volume manager that is associated with the device group: either the Solaris Volume Manager for Sun Cluster resource.	Scalable device-group resource. One resource is created for each scalable device group that you are using for Oracle files.
Resource type: `SUNW.ScalMountPoint` Resource name: `scal-mp-dir-rs`, where `mp-dir` is the mount point of the file system, with `/` replaced by `–` Resource group: `scalmnt-rg`	Offline-restart dependency on the scalable device-group resource, if any. If you are using a file system on a qualified NAS device without a volume manager, this resource does not depend on any other resources.	Scalable file system mount point resource. One resource is created for each shared file system that you are using for Oracle files.

Note - For detailed information for the resource configuration for zone clusters, see the figures in Appendix A, Sample Configurations of This Data Service.
