Enabling Cluster Support in VxVM
NOTE Cluster management software such as MC/ServiceGuard must be installed on the nodes of your cluster
system.
VxVM includes an optional cluster feature that enables VxVM to be used in a cluster environment.
The cluster functionality in VxVM allows multiple hosts to simultaneously access and manage a set of
disks under VxVM control. A cluster is a set of hosts sharing a set of disks; each host is referred to as
a node in the cluster.
Enable the cluster functionality in VxVM as follows:
Step 1. Obtain a license for the Volume Manager cluster feature from your Customer Support channel.
Step 2. Install the software packages onto each system (node) to be included in the cluster as described in
Chapter 2, “Installing VERITAS Volume Manager,” on page 25.
Step 3. Initialize VxVM using the vxinstall procedure.
Step 4. Set up and start the VEA as described in “Starting the VEA Service” on page 54.
Step 5. Configure shared disks as described in “Configuring Shared Disks” on page 58.
