Once the required Ethernet switch and network configurations and settings are made and in effect,
proceed with the remainder of the pairing process.
Configure Primary Gateway to expect Secondary Gateway
Set the number of ‘cluster expected-nodes’ on the ‘primary’ gateway to ‘2’ so that later it will pair
with the ‘secondary’ gateway and synchronize the configuration database. To do this, issue the
following commands on the ‘primary’ gateway:
> enable
# config term
# cluster expected-nodes 2
# show cluster global
hp-gateway1 [hp-redundant1: master] (config) # cluster expected-nodes 2
*hp-gateway1 [hp-redundant1: master] (config) # show cluster global
Cluster ID: 00600-0008-6090
Cluster name: hp-redundant1
Management IP: 0.0.0.0/0
Cluster master IF: eth1
Cluster node count: 1
Node Status:
Node ID: 1 <--- (local node)
Host ID: e4111da840b0
Hostname: hp-gateway1
Node Role: master
Node State: online
Node internal address: 10.61.184.238, port: 60102
Node external address: 10.61.184.238
Recv. Heartbeats from: -1
Send Heartbeats to: -1
At this time, only the primary gateway should be displayed with the ‘show cluster global’ command.
The ‘primary’ gateway will be shown as ‘master’ status. Also note that even though ‘cluster expected
nodes’ was set to ‘2’, that because membership only includes the current primary gateway the
current node count is only 1.
Configure Ethernet Port Bonding on Primary Gateway
Network settings to establish port bonding will now be made on the ‘primary’ gateway. Please refer
to the ‘Configuring Interface Bonding’ and ‘Gateway Management Network Configuration’ sections
of ‘HP VMA SAN Gateway Installation and Configuration Guide (P/N AM456-9025A) for additional
detail. Configure bonding of the eth1 and eht2 ports on the ‘primary’ VMA SAN Gateway using the
gateway CLI as follows:
On the ‘primary’ gateway, bond the network interfaces eth1 and eth2 to form the bonded interface
eth0 by issuing the following commands:
# network bond eth0 mod
e <agg-mode>
interface eth1 interface eth2 # write memory
Where <agg-mode> is the link aggregation bonding mode. It is recommended for simplicity and
most widely accepted bonding mode to use the ‘balance-rr’ mode; however, additional bonding
modes that could be used with redundant gateway pairs are:
• balance-rr - Round robin balancing
