82 IBM System Storage N series Hardware Guide

Node requirements

Nodes include the following requirements:

򐂰 The nodes must be one of the following system models that are configured for mirrored

volume use. Each node in the pair must be the same model:

– N5000 series systems, except for the N5500 and N5200 systems

– N6040, N6060, and N6070 systems

– N7600, N7700, N7800, and N7900

– N6210 and N6240 systems

򐂰 Each node requires a 4 Gbps Fibre Channel/Virtual Interface (FC-VI) adapter. The slot

position depends on the controller model. The FC-VI adapter is also called a VI-MC or

VI-MetroCluster adapter.

򐂰 The 8 Gbps FC-VI adapter is supported only on the N6210 and N6240 systems.

License requirements

The following licenses must be enabled on both nodes:

򐂰 cf (cluster failover)

򐂰 syncmirror_local

򐂰 cf_remote

7.3 Configuring the HA pair

This section describes how to start a new standard HA pair configuration for the first time. It

also describes how to enable licenses, set options, configure networking, test the

configuration, and address the modes of HA pair configurations.

The first time that you start the HA pair, ensure that the nodes are correctly connected and

powered up. Then, use the setup program to configure the systems. When the setup program

runs on a storage system in an HA pair, it prompts you to answer questions specific for HA

pairs.

Consider the following questions about your installation before you proceed through the setup

program:

򐂰 Do you want to configure VIFs for your network interfaces?

򐂰 How do you want to configure your interfaces for takeover?

Tip: For more information about supported cards and slot placement, see the

appropriate hardware and service guide on the IBM NAS support site.

Consideration: Strict rules apply for how the back-end switches are configured. For more

information, see IBM System Storage N series Brocade 300 and Brocade 5100 Switch

Configuration Guide, which is available at this website:

http://www.ibm.com/storage/support/nas

Strict rules also apply for which firmware versions are supported on the back-end switches.
