20 HP VMA SAN Gateway Installation and Configuration Guide AM456-9025A
Defining the Configuration Type
Before you begin the configuration process, you should have defined a configuration type and be
familiar with its parameters.
•
Standalone—Consists of one SAN Gateway with between one and two attached SAN
Gateways, as shown in the
Single HP VMA SAN Gateway with 1–2 HP VMA-series Memory
Arrays, Non Redundant on page 12.
Note:
A standalone SAN Gateway is considered to be a single node cluster. For this reason, you
can configure the same parameters for a standalone SAN Gateway node as you would for the
master node in a several node cluster.
•
High-Availability (Redundant) Pair—Consists of two SAN Gateways, a designated master and
standby node, and one or two HP VMA-series Arrays, as shown in the
Redundant Pair of
VMA-series SAN Gateways with 1–2 HP VMA-series Memory Arrays, Highly Available on
page 12. Additional SAN Gateway nodes are designated as normal nodes.
Note:
The pairing of two HP VMA SAN Gateway nodes for a High Availability (HA) or redundant
configuration is achieved by following the Redundant Gateway Pairing Process documented in the
Redundant Gateway Pairing Process Guide
.
Master and Standalone Node Parameters
The first HP VMA SAN Gateway added to a HP VMA SAN Gateway cluster becomes the master
node. A standalone SAN Gateway node is in effect a single master node cluster. For this reason, you
are prompted to answer the same configuration questions for a standalone node as you would for
the master node of a multi-node cluster. For an initial gateway bring-up, use the provided defaults
for cluster interface name, cluster id, cluster management IP, and netmask values.
The master node is the default gateway for all cluster management tasks, such as analyzing
performance for containers, LUNs, and targets; creating and exporting LUNs, or creating and
deleting initiator groups.
Cluster Management IP Address
(VIP for MG cluster access for redundant
gateways.)
Cluster Management IP Netmask
Cluster Expected Nodes (Initially "1".
Change the value after following
instructions in the
Redundant Gateway
Pairing Process Guide.
