At any one time, there can only be one active master node and one standby node in a cluster.
Note:
Prerequisites
You should have already successfully completed the following tasks.
• Configured the master HP VMA SAN Gateway node, defining the global cluster parameters in
the process.
• Set up HP VMA-series Memory Array nodes, as described in the
Installation and Service Guide
• Configured a secondary HP VMA SAN Gateway, taking on the global cluster parameters of
the master VMA SAN Gateway node.
For more information on these topics, see
page 15.
Configuring Interface Bonding
To form a management cluster, the Gigabit interfaces on each Gateway (eth1 and eth2) must be
configured as the bonded interface eth0.
Redundant gateway pair configurations require that the management traffic and cluster traffic
Note:
both share the same physical links. You can configure a bonded network interface to provide port/
cable redundancy. For more information, see
page 49.
Interface bonding is the bundling of several physical ports together to form a single logical channel.
One bonding method is Link Aggregation Control Protocol (LACP), which can be used to allow
network devices to negotiate the automatic bundling of links with other devices that implement
LACP.
Guidelines for Interface Bonding
When implementing interface bonding, follow these guidelines:
• Bond one or more network interfaces together using the
For interface bonding, eth0 is defined as a bonded interface consisting of two or more network
interfaces. All bonded interfaces share the same subnet. The Integrated Lights Out (iLO)
management port cannot be configured for general gateway management tasks. For more
information on interface bonding see HP VMA SAN Gateway User's Guide.
