When you configure your Sun NAS device for use with Oracle Real Application Clusters (RAC), you must meet the following requirements.

• You must create a volume on each Sun NAS device for storing Oracle database files, namely:

  • Data files

  • Archived redo log files

• You must create a quota tree (qtree) for the each directory in the following list:

  • The directory that contains Oracle data files for the cluster

  • The Oracle home directory that is to be mounted on each node

• On each Sun NAS device, you must add an entry to the /etc/exports file for the root of the volume that you created for storing Oracle database files.

• You must ensure that the volume is exported without the nosuid option.
