About this task

Multipath software provides a redundant path to the storage array in case one of the physical paths is disrupted. Before you can use multipathing, you need to install the Lenovo ThinkSystem DSM Installer for DE Series. This installer contains the multipath software for Windows.

Windows installations use the native MPIO Device Specific Module(DSM) driver for failover. When you install Lenovo ThinkSystem DSM Installer for DE Series, the DSM driver is installed and enabled.

When installing the DSM for Windows, you must first install optional Microsoft multipath I/O (MPIO) feature through the Server Manager console or by following the command under PowerShell with administrator privilege:

Enable-WindowsOptionalFeature -Online -FeatureName MultiPathIO

Once completed, you must reboot system and install the DSM by installing the Lenovo ThinkSystem DSM Installer for DE Series package. The Microsoft multipath I/O feature must be installed prior to installing the DSM for MPIO to work properly.
