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

Serviceguard Configuration for Oracle 9i RAC
Creating a Storage Infrastructure with CFS
Chapter 3 161
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 following example, both the Oracle software and datafiles reside
on CFS. There is a single Oracle home. The following three CFS file
systems are created for Oracle home, Oracle datafiles, and SRVM data:
/cfs/mnt1 – for Oracle Base and Home
/cfs/mnt2 – for Oracle datafiles
/cfs/cfssrvm - for SRVM data
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”.
IMPORTANT Creating a rootdg disk group is only necessary the first time you use
the Volume Manager. CVM 4.1 or later does not require a
rootdg.
2. Create the Cluster 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
