Using Serviceguard Extension for RAC, 5th Edition, June 2007

Serviceguard Configuration for Oracle 10g RAC
Creating a Storage Infrastructure with CFS
Chapter 2 93
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.
In the example below, both the Oracle RAC software and datafiles reside
on CFS. There is a single Oracle home. Three CFS file systems are
created for Oracle home, Oracle datafiles, and for the Oracle Cluster
Registry (OCR) and vote device. The Oracle Cluster Software home is on
a local file system.
/cfs/mnt1 – for Oracle Base and Home
/cfs/mnt2 – for Oracle datafiles
/cfs/mnt3 - for OCR and Vote device
Initializing the Veritas Volume Manager
Use the following steps to create a two node SGeRAC cluster with CFS
and Oracle:
1. Initialize the Veritas Volume Manager
If not already done, install the VxVM license key on all nodes. Use
the following command:
# vxinstall
(For each question raised when running the vxinstall command to
install the VxVM licence key, respond with “n”.)
NOTE CVM 4.1 or later does not require rootdg
2. Create the Cluster ASCII file:
# cd /etc/cmcluster
# cmquerycl -C clm.asc -n ever3a -n ever3b
Edit Cluster file
3. Create the Cluster
# cmapplyconf -C clm.asc
4. Start the Cluster
# cmruncl
