Configuring The Ha Pair - IBM N Series Hardware Manual

Node requirements
The following are the requirements for the nodes:
The nodes must be one of the following system models 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 FC-VI (Fibre Channel/Virtual Interface) adapter. The slot
position is dependent on the controller model. The FC-VI adapter is also called a VI-MC or
VI-MetroCluster adapter.
Tip: For information about supported cards and slot placement, see the appropriate
hardware and service guide on the IBM NAS support site.
The 8-Gbps FC-VI (Fibre Channel/Virtual Interface) adapter is supported only on the
following systems:
– N6210 and N6240
License requirements
The following licenses must be enabled on both nodes:
cf (cluster failover)
syncmirror_local
cf_remote
Consideration: Strict rules apply for how the back-end switches are configured. For more
information, see the IBM System Storage N series Brocade 300 and Brocade 5100 Switch
Configuration Guide found at:
http://www.ibm.com/storage/support/nas
Strict rules also apply for which firmware versions are supported on the back-end switches.
For more information, see the latest IBM System Storage N series and TotalStorage NAS

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 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.
