For information on how to set up and configure a redundant VMA SAN Gateway pair, see the
Configuring a Redundant Pair of VMA SAN Gateways - Process Guide .
Note: The roles of master and secondary refer to nodes for cluster configuration management. The
pairing of SAN Gateway nodes for a High Availability (HA) configuration is achieved through
physical cabling.
SAN Gateway Cluster Management
Management tasks can be performed either in the HP VMA Web Interface or in the CLI. This
chapter explains the tasks with CLI examples and gives references to CHAPTER 2, “ Manage,
Monitor, and Administer with the HP VMA Web Interface” on page 23, where the same tasks are
described using HP VMA Web Interface tools.
Master Node Parameters
All global cluster parameters are defined on the master node, and then are automatically inherited
by the secondary node added to the redundant pair. It is recommended that you become familiar
with the following information before performing cluster management tasks.
Public interface name This specifies the Ethernet port used for gateway management. If
only a single Ethernet cable is used to connect the Gateway node,
then eth1 should be used. If both eth1 and eth2 are cabled to the
network, then they should be bonded as eth0, and eth0 should be
used as the public interface.
Public interface IP address The public interface IP address.
Note: DHCP is not recommended, instead use the zeroconf utility
after configuring a VLAN. For more information, see Network
Interface Commands on page 182.
Public interface netmask The public interface netmask
Default gateway The Default Gateway is set on a per/node basis. When a node is
part of a redundant pair, the Global Default Gateway takes
precedence. The Default Gateway is recommended for access to a
node in a cluster from outside of the local network.
Global default gateway Enable or disable. The Global Default Gateway is set and used for
the redundant pair. HP recommends that you enable the global
default gateway.
DNS server name(s) Specify a primary and, optionally, a secondary DNS server.
DNS Domain name The name of your local domain.
Hostname A local hostname for the HP VMA SAN Gateway.
