I've inherited a Windows 2016 Server failover cluster, and one node was causing problems (with DISM, and with weird behaviour including failing to live migrate). So I have reinstalled Windows and added Failover Cluster Manager, MPIO and Hyper-V.
The cluster storage (SAS MSA20400) connects, but it identifies several disks and says that two cannot be distinguished. These are 2 and 5, which are clustered disks in the MSA... Is there an HP driver that should be added? The MPIO utility is not identifying the MSA manufacturer and part number, which I guess might be part of the problem.
Again, I have never done this sort of work on the cluster and it's in production so I am treading very carefully.
