Connecting Multipath LUN SHD to Windows Server 2008 and Windows Server 2012

    In the previous article, we looked at “Connecting Multipath LUN storage systems to VMware ESXi and Debian GNU / Linux”. This article continues. Let me remind you that the configuration with two SAN switches is used, to each of which, the storage system is connected with two links.

    Connecting Multipath LUN storage to Windows Server 2012

    Multipath Input Output is a multi-path connection system for block devices. It is required to duplicate connection channels in order to increase fault tolerance and performance due to the fact that the server can access the device through several channels.

    This is how the system sees LUNs without MPIO support:

    If MPIO is disabled for any reason, you need to enable it. To do this, in the “Dashboard” select the “Management” menu and the “Add Roles and Components” item.

    In the “Add Roles and Components Wizard”, go to the “Components” item and select “Multipath I / O” from the list, then press the “Install” virtual button.

    After that, go to the disk array management system in the “Server Manager” and through the “tools” menu we call the MPIO dialog:

    On the “Multipath devices detection” tab, we see the LUNs we need and click the “Add” button.

    The system prompts you to reboot. We agree. After rebooting, all LUNs are available as MPIO devices:

    Now they need to be connected to the system, after which you can create volumes:

    Done. Now the created volumes are available in the system:

    Connecting Multipath LUN DSS to Windows Server 2008

    Above, we looked at how to connect LUN to Windows Server 2012. In Windows Server 2008, the procedure is somewhat different.

    After the system has booted, we launch the Server Manager:

    In the "Action" menu, select the item "Add components":

    In the list, activate the switch "Multi-path I / O" and go through all the installation steps:

    Done. Now you need to activate the recognition of paths. To do this, go to the “Control Panel” and switch to the “Small icons: View mode:

    Call up the“ MPIO ”configuration panel:

    Where go to the“ Multipath devices detection ”tab. The list of “Equipment Code” will display the necessary LUNs. Press the virtual button "Add":

    The system prompts you to reboot. We agree:

    After rebooting in the Server Manager, go to the “Storage” → “Disk Management” and see the LUNs as a Multipath device:

    Now you can create volumes and connect to the system:

    Is done. Now the disk is available in the system. To make sure, you can open "My Computer":
