Issues in Failover Cluster Disk

Osama Mansoor 86 Reputation points

Hi Experts,

We have recently installed Three HP DL360 Servers with SAN.

Now my target is to run HYPER-V (Windows Server 2019 Std) therefore i do following steps

  1. Network Configuration (Ethernet, Teaming)
  2. Installed Failover Cluster, MPIO and Hyper-V
  3. Configured Virtual Switch (IP Assignment)
  4. Failover Cluster

Validate Three Servers (Successful)
Add Quorum Disk (Attached with One Server)
Configured Cluster Shared Volume (Two Different Volume)

Issue: After Configuring CSV I am getting cluster error regarding CSV however i am re tried to Validate Cluster but it also shows error.

Servers become unresponsive, unable to open disk management (Take loading), When go to C: Drive in ClusterStorage Folder it takes too much time to load and hangs.

All Errors and Screen-Shots are attached please help me.
