•For redundancy in a dual controller (duplex) configuration, ensure each host network interface is configured to connect to both storage array controllers.
•For optimal load balancing, ensure each host network interface that is used for iSCSI traffic is configured to connect to each storage array controller.
•It is recommended that each host network interface only establishes one iSCSI session per storage array controller.
NOTE: The utility tries to follow the guidelines for the host connectivity whenever possible based on the available host network interfaces and their connectivity with the iSCSI host ports of the storage array.
Configure The Storage Array Using PowerVault MDCU
To configure the
1.Launch the utility (if it is not launched automatically) from the server with access to the management ports of the storage array(s) to be configured.
–For Windows, click Start → All Programs → Dell → MD Storage Software → Modular Disk Configuration
Utility.
–For Linux, click the MDCU icon on the desktop or navigate to the /opt/dell/mdstoragesoftware/ mdconfigurationutility directory in a terminal window and run PowerVault MDCU.
The MDCU automatically discovers all the available storage arrays.
2.In the Discover MD Arrays window, select the iSCSI storage array you want to configure.
3.In the Selected Array window, review current port and session information.
4.Click Config Wizard, to start the iSCSI configuration wizard.
5.Complete the steps in Config Wizard to configure your iSCSI storage array.
6.In the Array Configuration Summary window, review and apply your configuration settings.
7.Click Create iSCSI Sessions, to create
8.Verify that communication is established between the storage array and host server.
NOTE: For more information on MDCU, see the MDCU online help.
Post Connection Establishment Steps
After iSCSI connectivity is established between the host server(s) and the storage array, you can create virtual disks on the storage array using MD Storage Manager and these virtual disks can be utilized by the host server(s). For more information about storage planning and using MD Storage Manager, see the Administrator's Guide at support.dell.com/ manuals.
