Using Serviceguard Extension for RAC, 7th Edition, September 2008

If you are installing CFS 4.1 or 5.0 with either the Storage Management Suite (SMS) bundle or
Mission Critical Operating Environment (MCOE), use the appropriate product number as
described below:
• SGeRAC and CFS 4.1 are included with the HP Serviceguard SMS bundle or MCOE.
• SGeRAC and CFS 5.0 are included with the HP Serviceguard Storage Management Suite
bundle or MCOE.
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
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.
# cfscluster config -s
The following output will be displayed:
