Oracle^® Solaris Cluster Data Service for Oracle Real Application Clusters Guide

Creating an Oracle ASM Instance and Disk Groups

Oracle ASM installation consists of installing and creating an Oracle ASM instance and configuring the required Oracle ASM disk groups. An Oracle ASM disk group is a collection of disk devices to store data files that Oracle ASM instances manage as a unit. Oracle ASM instances mount disk groups to make Oracle ASM files available to database instances.

How to Create an Oracle ASM Instance and Disk Groups

Before You Begin

• Ensure that the Oracle Grid Infrastructure software is already installed.

• Ensure that the Support for Oracle RAC framework is running on all nodes where the Oracle ASM instance is to be created.

• Ensure that the file system where the Oracle ASM $ORACLE_HOME directory will reside is already created.

1. Assume the root role on a cluster node.
2. Install and configure an Oracle ASM instance and create disk groups.

   Use Oracle ASM Configuration Assistant (ASMCA). See the appropriate Oracle ASM documentation for instructions.
