Creating Storage Management Resources by Using Oracle Solaris Cluster Maintenance Commands

The tasks in this section are alternatives for the resource-configuration steps in How to Register and Configure Storage Resources for Oracle Files by Using clsetup. The following information is in this section:

• Resources for Scalable Device Groups and Scalable File-System Mount Points

• Resources for the Sun QFS Metadata Server

• How to Create a Resource for a Scalable Device Group in the Global Cluster

• How to Create a Resource for a Scalable Device Group in a Zone Cluster

• How to Register and Configure Resources for the Sun QFS Metadata Server in the Global Cluster

• How to Register and Configure Resources for the Sun QFS Metadata Server for a Zone Cluster

• How to Create a Resource for a File-System Mount Point in the Global Cluster

• How to Create a Resource for a File-System Mount Point in Zone Cluster

The following resources to represent storage for Oracle files are required:

• Resources for scalable device groups and scalable file-system mount points

• Resources for the Sun QFS metadata server

Resources for Scalable Device Groups and Scalable File-System Mount Points

If you are using Solaris Volume Manager for Sun Cluster or VxVM, configure storage resources as follows:

• Create one scalable resource group to contain all resources for scalable device groups.

• Create one resource for each Solaris Volume Manager for Sun Cluster multi-owner disk set or VxVM shared-disk group that you are using for Oracle files.

If you are using Sun QFS or qualified NAS devices, configure storage resources as follows:

• Create one scalable resource group to contain all resources for scalable file-system mount points.

• Create one resource for each Sun QFS shared file system or NFS file system on a qualified NAS device that you are using for Oracle files.

The resource that represents a Sun QFS shared file system can start only if the file system's Sun QFS metadata server is running. Similarly, the resource that represents a Sun QFS shared file system can stop only if the file system's Sun QFS metadata server is stopped. To meet this requirement, configure a resource for each Sun QFS metadata server. For more information, see Resources for the Sun QFS Metadata Server.

Resources for the Sun QFS Metadata Server

If you are using the Sun QFS shared file system, create one resource for each Sun QFS metadata server. The configuration of resource groups for these resources depends on the version of Oracle that you are using:

• Configuration of Sun QFS Resource Groups With Oracle 9i and Oracle 10g Release 2 or 11g

• Configuration of Sun QFS Resource Groups With Oracle 10g Release 1

Configuration of Sun QFS Resource Groups With Oracle 9i and Oracle 10g Release 2 or 11g

If you are using Oracle 9i, Oracle 10g release 2, or Oracle 11g, the configuration of resource groups depends on the number of file systems in your configuration.

• If your configuration contains a small number of file systems, create one resource group for all resources for the Sun QFS metadata server.

• If your configuration contains a large number of file systems, configure resources for the Sun QFSmetadata server in several resource groups as follows:

  • Distribute resources among the resource groups to ensure optimum load balancing.

  • Select a different primary node for each resource group to prevent all the resource groups from being online on the same node simultaneously.

Configuration of Sun QFS Resource Groups With Oracle 10g Release 1

If you are using Oracle 10g, Oracle Clusterware manages Oracle RAC database instances. These database instances must be started only after all shared file systems are mounted.

You might use multiple file systems for database files and related files. For more information, see Sun QFS File Systems for Database Files and Related Files. In this situation, ensure that the file system that contains the Oracle Clusterware voting disk is mounted only after the file systems for other database files have been mounted. This behavior ensures that, when a node is booted, Oracle Clusterware resources are started only after all Sun QFS file systems are mounted.

If you are using Oracle 10g release 1, the configuration of resource groups must ensure that Oracle Solaris Cluster mounts the file systems in the required order. To meet this requirement, configure resource groups for the metadata servers of the file systems as follows:

• Create the resources for the metadata servers in separate resource groups.

• Set the resource group for the file system that contains the Oracle Clusterware voting disk to depend on the other metadata resource groups.
