Preparing Your Systems for Clustering 39
The "iSCSI Configuration Worksheet" on page 77 helps you plan your
configuration. Recording host server and storage array IP addresses at a single
location will help you configure your setup faster and more efficiently.
Configuring iSCSI on Your Storage Array
The following sections contains step-by-step instructions for configuring
iSCSI on your storage array. However, before beginning, it is important to
understand where each of these steps occur in relation to your host
server/storage array environment.
Table 3-1. Standard Terminology Used in iSCSI Configuration
Term Definition
CHAP (Challenge
Handshake
Authentication Protocol)
An optional security protocol used to control access to an
iSCSI 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 "Creating a Host Group" on page 48.
host or host server A server connected to the storage array through 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.
iSCSI host port The iSCSI port (two per controller) on the storage array.
iSNS (Microsoft Internet
Storage Naming Service)
An automated discovery, management, and configuration
tool used by some iSCSI devices.
management station The system from which you manage your host
server/storage array configuration.
storage array The enclosure containing the storage data accessed by the
host server.
target An iSCSI port on the storage array that accepts and
responds to requests from the iSCSI initiator installed on
the host server.
