Array Setup and iSCSI Configuration

To use the storage array, you must configure iSCSI on both the host server(s) and the storage array. Step-by-step instructions for configuring iSCSI are described in this section. However, before proceeding here, you must have already installed the Microsoft iSCSI initiator and the MD Storage Manager software. If you have not, refer to Software Installation and complete those procedures before attempting to configure iSCSI.

NOTE: Although some of these steps shown in this section can be performed in MD Storage Manager from a management station, the iSCSI initiator must be installed and configured on each host server.

Before You Start

Before you begin configuring iSCSI, you should fill out the iSCSI Configuration Worksheet (Table 4-2 and Table 4-3). Gathering this type of information about your network prior to starting the configuration steps should help you complete the process in less time.

NOTE: If you are running Windows Server 2008 and elect to use IPv6, use Table 4-3 to define your settings on the host server and storage array controller iSCSI ports. IPv6 is not supported on storage array controller management ports.

Terminology

The table below outlines the terminology used in the iSCSI configuration steps later in this section.

CHAP (Challenge Handshake

An optional security protocol used to control access to an iSCSI

Authentication Protocol)

storage system by restricting use of the iSCSI data ports on both

 

the host server and storage array. For more information on the

 

types of CHAP authentication supported, see Understanding

 

CHAP Authentication.

host or host server

A server connected to the storage array via iSCSI ports.

host server port

iSCSI port on the host server used to connect it to the storage

 

array.

iSCSI initiator

The iSCSI-specific software installed on the host server that

 

controls communications between the host server and the storage

 

array.
