AM456-9007B Rev 02 HP VMA SAN Gateway Installation and User Guide 235
The following is an example of configuring simple round-robin balance mode for
the bonded interface, which does not require any switch changes.
These commands must be entered on each node to enable bonding:
This will create a round-robin bond called eth0 using interfaces eth1 and eth2 and
should move the IP address configured for eth1 to eth0. You will need to verify that
this IP address move occurred. A reboot of the HP VMA SAN Gateways may be
required after all nodes have been changed for the cluster to reconnect.
If bonding cannot be used, then set the cluster interface to the same port as the
management (cluster master) interface, which must be done from the CLI on each
node:
Note: Many of the G5.0.x configurations were installed using eth2 as the cluster
interface. These configurations will need to change to either use bonding on eth0
or switch to using eth1.
To hide the cluster multicast traffic, a VLAN can be used for the cluster interface.
This requires changing network settings on your network switch. Refer to the
administration guide for your network switch.
Multiple Gateways with 1–2 3000-Series Arrays Each, Highly Available
Figure D.3 on page 237 shows an example configuration of five HP VMA SAN
Gateway nodes and twelve VMA Arrays. There are two HA pairs and one Single
HP VMA SAN Gateway configuration. Up to 16 HP VMA SAN Gateway nodes
can be configured in a vCLUSTER configuration.
