Preparing Your Systems for Clustering 37
Configuring the Shared Storage System
Before you begin configuring iSCSI, you must fill out the "iSCSI
Configuration Worksheet" on page 73. Gathering this type of information
about your network prior to starting the configuration steps helps you
complete the process faster.
Terminology
The following table outlines the terminology used in the iSCSI configuration
steps later in this section.
