Configuring a Redundant Pair of VMA SAN Gateways - Process Guide

19
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. Note that even though ‘cluster expected
nodes’ was set to ‘2’, 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 ‘Network Configuration Commands’ sections of HP VMA-
series SAN Gateway Installation and User Guide (P/N AM456-9007B-Rev 2) 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 mode <link-agg> interface eth1 interface eth2
# write memory
Where <link-agg> is the link aggregation bonding mode. It is recommended for simplicity and most
widely accepted LACP mode to use the ‘balance-rr’ bonding mode; however, additional bonding
modes that could be used with redundant gateway pairs are:
• balance-rr - Round robin balancing
• link-agg - Link Aggregation mode
• balance-alb - Adaptive load balancing
• link-agg-layer2+3 - Link aggregation layer 2 + 3 mode
• backup - Active/Backup mode
The above commands perform the bonding of Ethernet ports eth1 and eth2 to create the bonded port
eth0 and then saves the configuration changes. For many switches, if ‘balance-rr’ mode is used,
explicit switch port trunking of the bonded gateway ports is not needed; however, if any of the other
link aggregation modes are used, you will need to have configured port trunking on the switches
accordingly.
*hp-gateway1 [hp-redundant1: master] (config) # network bond eth0 mode balance-rr
interface eth1 interface eth2
Are you sure you wish to change networking modes? All cached content will be
lost, the cache modules will leave the cluster to set up networking, and remote
cli connections may be terminated. Continue? [no] yes
