Storage Planning with CFS
With CFS, the database software and database files (control, redo, data files), and archive logs
may reside on a cluster file system, which is visible by all nodes.
The following software needs to be installed in order to use this configuration:
• SGeRAC
• CFS
NOTE: For specific CFS Serviceguard Storage Management Suite product information refer to
your version of the HP Serviceguard Storage Management Suite Release Notes.
Configuration Combinations with Oracle 9i RAC
The following configuration combinations show a sample of the configuration choices (See
Table 3-1):
• Configuration 1 is for Oracle software and database files to reside on CFS.
• Configuration 2 is for Oracle software and archives to reside on CFS, while the database files
are on raw volumes either SLVM or CVM.
• Configuration 3 is for Oracle software and archives to reside on local file system, while
database files reside on CFS.
• Configuration 4 is for Oracle software and archive to reside on local file system, while the
database files are on raw volumes either SLVM or CVM.

NOTE: Mixing files between CFS database files and raw volumes is allowable, but not
recommended. RAC datafiles on CFS requires Oracle Disk Manager (ODM).
Using Single CFS Home or Local Home
With a single CFS home, the software installs once and all the files are visible on all nodes.
Serviceguard cluster services needs to be up for the CFS home to be accessible. For Oracle RAC,
some files are still local (/etc/oratab, /var/opt/oracle/, /usr/local/bin/).
With a local file system home, the software is installed and copied to every node’s local file
system. Serviceguard cluster services does not need to be up for the local file system to be
accessible. There would be multiple homes for Oracle.
