Creating a Storage Infrastructure with CVM
Chapter 254
Preparing the Cluster for Use with CVM
In order to use the VERITAS Cluster Volume Manager (CVM), you need
a cluster that is running with a special CVM package. This means that
the cluster must already be configured and running before you create
disk groups.
NOTE Cluster configuration is described in the previous section.
To prepare the cluster for CVM disk group configuration, you need to set
MAX_CONFIGURED_PACKAGES to 1 or greater in the cluster ASCII
configuration file, and ensure that only one heartbeat subnet is
configured. Then use the following command, which creates the special
package that communicates cluster information to CVM:
# cmapplyconf -P /etc/cmcluster/cvm/VxVM-CVM-pkg.conf
WARNING This file should never be edited.
After this command completes successfully, you can start the cluster and
create disk groups for shared use as described in the following sections.
When you start the cluster, it will now run with a special system
multi-node package named VxVM-CVM-pkg, which is on all nodes. This
package is shown in the following output of the cmviewcl -v command:
CLUSTER STATUS
