Defining Cluster Name and Host Names
Names for the cluster and each HP VMA SAN Gateway may be set via the serial
console port on the Master Gateway or via the cluster management VIP address:
• Cluster name to identify the VMA-series SAN Gateway.
• Host names for each HP VMA SAN Gateway in the cluster. Typically, these
would be given obvious names such as “vmg-n1” and “vmg-n2” or something
similar.
Configuring Network Connections
The second step of Phase 2 is to configure support on the cluster and network
switches for bonded interfaces and VLANs.
Interface Bonding
Interface bonding is the bundling of several physical ports together to form a single
logical channel. One bonding method is the Link Aggregation Control Protocol
(LACP), which can optionally be used to allow, network devices to negotiate the
automatic bundling of links with other devices that implement LACP.
To utilize interface bonding, you must (1) bond together one or more network
interfaces together using the network bond command and (2) if using LACP,
ensure that the network switches are LACP-enabled. For more information, see
Network Bond Commands on page 150.
Depending on the switch’s capabilities and configuration, the port LACP settings
may be either active or passive. Active mode is recommended because no non-
aggregated traffic is expected from the HP VMA SAN Gateway.
If interface bonding is used, eth0 is defined as a bonded interface consisting of two
or more network interfaces. All bonded interfaces share the same subnet. The LOM
port cannot be configured using vCLUSTER. For more information on interface
bonding see Network Interface Commands on page 148.
Cluster VLAN Configuration
The VMA-series SAN Gateway uses a separate cluster network for low-latency,
low-bandwidth communication between HP VMA SAN Gateways in a cluster.
