Get the wwn of multipatch luns linux3/15/2023 ![]() ![]() If you are deploying a cluster, configure MPIO on all nodes. To make sure that MPIO has been installed on your Windows Server, run this command: Run the PowerShell console as an administrator and use the following command to install the Windows Server feature: Finish MPIO installation and restart the server.Find and check the Multipath I/O in the Features list.From a graphical interface using Server Manager console.There are two ways to install it in Windows Server 2016: Microsoft MPIO provides high availability and load balancing using multiple connections to a storage, doesn’t depend on any protocols and supports disk array and storage connection using iSCSI, Fiber Channel and SAS.īy default, MPIO module is disabled on Windows Server. Windows Server supports multi-path input output (MPIO) starting from Windows Server 2008 R2. Installing MPIO Installation on Windows Server 2016/2012R2 So, MPIO is an important component of a fail-tolerant storage and data access system, and MPIO modules can distribute the load on the same LUN across different paths. MPIO may use an alternative logical path if one or more components fail, thus making an operating system use another route to access a logical disk (LUN) maintaining data access consistency. If MPIO is enabled, a server may access data on a storage using multiple paths that makes access to a connected LUN faster and allows using multiple network or HBA adapters. If the OS supports MPIO, it will see each of the disks presented to it in one copy. The following screenshot shows that Windows without MPIO sees 2 drives with different paths, which are in fact the same LUN (the list of presented disks may be displayed using the Get-Disk PowerShell cmdlet). If a server can access a logical disk (LUN) using multiple iSCSI initiator adapter or multiple Fibre Channel ports, the Device/Disk Manager without the MPIO module will show more LUNs than there actually are (= the number of paths to a LUN * the number of presented LUNs) if an MPIO module is not installed.
