  • Page 37: Configuring The Shared Storage System

    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.
  • Page 38 Using Internet Storage Naming Service Server Internet Storage Naming Service Server (iSNS) eliminates the need to manually configure each individual storage array with a specific list of initiators and target IP addresses.

  • Page 43 NOTE: If you elect to use CHAP authentication, you must configure it on both the storage array (using MD Storage Manager) and the host server (using the iSCSI initiator) before preparing virtual disks to receive data. If you prepare disks to receive data before you configure CHAP authentication, you will lose visibility to the disks after CHAP is configured.
  • Page 44 NOTE: If you choose to configure mutual CHAP authentication, you must first configure target CHAP. Remember, in terms of iSCSI configuration, the term target always refers to the storage array. Configuring Target CHAP Authentication on the Storage Array 1 From MD Storage Manager, click the iSCSI tab and then Change Target Authentication.
