You cannot claim multipath disks after installing MPIO and a third-party multipath solution in Windows Server 2016

Applies to: Windows Server 2016

Symptoms


After you install the Multipath I/O (MPIO) feature and a third-party multipath solution in Windows Server 2016, you cannot claim any multipath disks. Therefore, Windows may have multiple paths to access storage at the same time.

This situation may cause data corruption of the storage content.

Cause


This issue can occur if the server isn't restarted after you successfully install the MPIO feature.

Resolution


To avoid this issue, restart the computer after you install the MPIO feature. Then, install the third-party multipath solution.
