I have a Hyper-V failover cluster with 2 nodes on 2012R2 with SAS directly attached storage.
Cluster uses 3 LUNs:
- 1st for CSV
- 2nd for Quorum disk
- 3rd for Path-through LUN to 1 virtual machine.
Before this cluster runs with 2012 and i have upgraded it to 2012R2 with update.
Both nodes can see and access all attached LUNs.
But when I tried to add 3rd LUN as availiable storage I got message "No disks suitable for cluster disks were found"
Why did this happens?
