Post Installation Tasks 43Automatic Configuration Using the Modular Disk Configuration UtilityNOTE: If MDCU is not installed, it can be installed from the MD3600i Seriesresource media.The MDCU provides a consolidated approach for configuring the iSCSI networkof host servers and iSCSI-based storage arrays using a wizard-driven interface.This utility also enables the user to configure the iSCSI sessions of the host serveraccording to the best practices and to achieve load-balanced paths with thestorage array iSCSI host ports.NOTE: MDCU is only applicable to iSCSI-based MD3600i Series storage arrays.If you select Launch the MDCU after reboot during the installation of thehost software, the utility automatically launches after the next host serverreboot. This utility can also be launched manually.The utility has a context sensitive online help to guide you through each stepof the wizard.The MDCU performs:• Storage array configuration• Host configurationStorage Array ConfigurationBefore a host iSCSI initiator and an iSCSI-based storage array cancommunicate, they must be configured with information such as which IPaddresses and authentication method to use. Since iSCSI initiators establishconnections with an already configured storage array, the first task is toconfigure your storage arrays to make them available for iSCSI initiators.This utility requires network access to the management ports of the storage arraysyou wish to configure. You must have a properly functioning networkinfrastructure before attempting to configure your storage arrays. If your storagearrays are already configured, you can skip directly to the host configuration.This configuration task generally involves the following steps:1 Discover available storage array(s) for configuration.2 Select a storage array to configure.3 Set a storage array name and password.4 Configure the IP protocols and addresses for the management ports.
