Using Serviceguard Extension for RAC, 6th Edition, April 2008

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
# cmviewcl
The following output will be displayed:
CLUSTER STATUS
ever3_cluster up
NODE STATUS STATE
ever3a up running
ever3b up running
