Using Serviceguard Extension for RAC, 9th Edition, September 2010

IMPORTANT: Creating a rootdg disk group is only necessary the first time you use the Volume
Manager. CVM 5.0 or later does not require a rootdg.
Using CVM 5.x or later
This section has information on how to prepare the cluster and the system multi-node package
with CVM 5.x or later only, without the CFS filesystem (on HP-UX releases that support them).
See “About Veritas CFS and CVM from Symantec” (page 18).
For more detailed information on how to configure CVM 5.x or later, refer the latest edition of
the Managing Serviceguard user guide.
Preparing the Cluster and the System Multi-node Package for use with CVM 5.x or later
1. Create the cluster file.
# cd /etc/cmcluster
# cmquerycl -C clm.asc -n ever3a -n ever3b
Edit Cluster file.
NOTE: To prepare the cluster for CVM configuration, you need to be sure
MAX_CONFIGURED_PACKAGES to minimum of 3 (the default value for
MAX_CONFIGURED_PACKAGES for Serviceguard A.11.20 is 300) cluster configuration file.
In the sample, set the value to 10.
2. Create the cluster.
# cmapplyconf -C clm.asc
• 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
3. Configure the Cluster Volume Manager (CVM).
To configure and start the CVM stack, configure the system multi-node package,
SG-CFS-pkg. Unlike VxVM-CVM-pkg, the SG-CFS-pkg does not restrict heartbeat subnets
to a single subnet, and supports multiple subnets.
# cmapplyconf -P /etc/cmcluster/cfs/SG-CFS-pkg.conf
# cmrunpkg SG-CFS-pkg
When CVM starts up, it selects a master node. From this node, you must issue the disk group
configuration commands. To determine the master node, issue the following command from
each node in the cluster:
# vxdctl -c mode
The following output will be displayed:
