EMC VNX VG2/VG8 Gateway Configuration Setup Guide

Introduction

EMC CONFIDENTIAL

Table 1 shows the final octets (nnn) of the private LAN address for each component.

It is best to change the internal IP addresses of the VNX gateway from the system

defaults during installation. Changing the private IP addresses after the installation is

a complex process that involves blade downtime. Appendix B, “Change IP

Addresses,” provides steps to change the VNX gateway internal IP address after

installation.

If the customer is already using these default subnets in their public network, the

private LAN addresses should be changed at the installation time. Even though the

private LAN does not connect to the customer’s public LAN, the blades and Control

Station connect to both networks.

Note: If a customer has multiple VNX gateways, each system can have the same set of private

LAN addresses. A conflict occurs only if the same network exists in both the public and private

LANs. All VNX gateways attached to the same VNX array must have unique network

addresses in the Initiator Record Host IP Address field in the Unisphere interface to ensure that

the Host display for those VNX gateways appears correctly.

During the Control Station configuration, you can accept the defaults or enter

different addresses for the Control Station private LAN ports. The other components

are automatically configured to match. The new private LAN addresses must:

◆ Use a subnet mask of 255.255.255.0.

◆ Be in a subnet that is not used in the customer’s public network.
