Configuring and Managing Clusters
vCLUSTER Overview
Cluster management software provides for the central management of multiple HP
VMA SAN Gateways and VMA Arrays as nodes within a single system. Using
vCLUSTER, multiple HP VMA SAN Gateways and VMA Arrays may be
managed from the CLI or VMA Web Interface.
An HP VMA SAN Gateway cluster consists of one or more HP VMA SAN
Gateways (nodes), one of which is designated as the master node, and a second (in
a cluster of more than one node) is designated as the standby node. Any other nodes
in the cluster are designated as normal nodes. Should the master node fail, the
standby node replaces it and becomes the master node, and cluster management
traffic is automatically redirected to the new master node.
Cluster management activities include monitoring the HP VMA SAN Gateways
(nodes) in the HP VMA SAN Gateway cluster, stopping or rebooting nodes, and
upgrading the vSHARE running on the cluster. Every node in the cluster may be
managed using controls in the CLI or VMA Web Interface.
Cluster Network Configuration
Phase 2, System Network Configuration, includes the following procedures:
• Configuring Network Switches: The first step of Phase 2, System Network
Configuration, is to set up and define the network switches for the HP VMA
SAN Gateway cluster. During this phase you must configure the following IP
addresses, parameters, and names: the public interface IP address and netmask
