Post Installation Tasks 39Automatic Configuration Using the Modular Disk Configuration UtilityNOTE: If PowerVault MDCU is not installed, it can be installed from the PowerVaultMD series resource media.PowerVault MDCU provides a consolidated approach for configuring the iSCSInetwork of host servers and iSCSI-based storage arrays using a wizard-driveninterface. This utility also enables the user to configure the iSCSI sessions of thehost server according to the best practices and to achieve load-balanced pathswith the storage array iSCSI host ports.NOTE: PowerVault MDCU is only applicable to iSCSI-based PowerVault MD3200iseries storage arrays. It does apply to SAS-based PowerVault MD3200 seriesstorage 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 PowerVault 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.
