You must use Sun StorEdge QFS shared file system with hardware RAID support.
For detailed instructions for installing, configuring, and using Sun StorEdge QFS shared file system, see Sun StorEdge QFS and Sun StorEdge SAM-FS Software Installation and Configuration Guide and Sun StorEdge QFS and Sun StorEdge SAM-FS File System Administration Guide.
Ensure that the Sun StorEdge QFS software is installed.
Ensure that each Sun StorEdge QFS shared file system is correctly configured for use with Sun Cluster Support for Oracle Real Application Clusters.
Ensure that each Sun StorEdge QFS shared file system is mounted with the correct options for use with Sun Cluster Support for Oracle Real Application Clusters.
For the file system that contains binary files, configuration files, alert files, and trace files, use the default mount options.
For the file systems that contain data files, control files, online redo log files, and archived redo log files, set the mount options as follows:
In the /etc/opt/SUNWsamfs/samfs.cmd file or the /etc/vfstab file, set the following options:
stripe=width sync_meta=1 mh_write qwrite forcedirectio nstreams=1024 rdlease=300Set this value for optimum performance. wrlease=300Set this value for optimum performance. aplease=300Set this value for optimum performance.
Ensure that settings in the /etc/vfstab file do not conflict with settings in the /etc/opt/SUNWsamfs/samfs.cmd file. Settings in the /etc/vfstab file override settings in the /etc/opt/SUNWsamfs/samfs.cmd file.
Register and configure the data service for the Sun StorEdge QFS metadata server.
The next step depends on whether you are using the Sun StorEdge QFS file system for Oracle binary files and Oracle configuration files.
If you are using the Sun StorEdge QFS file system for Oracle binary files and Oracle configuration files, go to Creating Node-Specific Files and Directories for a Shared File System.
Otherwise, go to Installing Sun Cluster Support for Oracle Real Application Clusters Packages.
