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

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
# cmviewcl
The following output will be displayed:
CLUSTER STATUS
ever3_cluster up
NODE STATUS STATE
ever3a up running
ever3b up running
5. Configure the Cluster Volume Manager (CVM)
Configure the system multi-node package, SG-CFS-pkg, to configure and start
the CVM/CFS stack. Unlike VxVM-CVM-pkg, the SG-CFS-pkg does not restrict
heartbeat subnets to a single subnet and supports multiple subnets.
