We have windows 2012 R2 Hyper-V cluster (@ Node with FC CSV storage) and we have noticed that some VMs are not responding and VMs are not reachable along with host for few seconds. This is affecting application within VM. After moving the VM to another Host, its working fine.
We have tried following till now-
- All drivers and firmware are updated to latest , Tried multiple drivers for FC/ Network adapters
- Enabled /Diabled VMQ
- Cluster Validation result is fine
Now, we have only option to reformat the system and need your advise before doing that.
