Configuring Interface Bonding
In a High Availability vSHARE configuration, management traffic and cluster
traffic must both share the same physical links. The Gigabit interfaces on each HP
VMA SAN Gateway, eth1 and eth2, should be configured as a bonded interface,
eth0. A bonded network interface provides port/cable redundancy.
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 gateway node to enable bonding:
This creates 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.
There are many types of bonding modes available, see Network Bond Commands
on page 150 for more information on these modes.
Configuring Multipath I/O on vSHARE Clients
In a High Availability configuration, host servers access the LUNs via multiple
paths (in Figure 4.5 below, two paths vian HP VMA SAN Gateway 1 and two paths
