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.
