• Identifying and Using Existing Oracle Database Disk Groups on Oracle ASM
  Identify existing disk groups and determine the free disk space that they contain. Optionally, identify failure groups for the Oracle ASM disk group devices.
• Creating Disk Groups for Oracle Database Data Files
  If you are sure that a suitable disk group does not exist on the system, then install or identify appropriate disk devices to add to a new disk group.
• Creating Directories for Oracle Database Files
