I have a two-node failover cluster on Windows Server 2012。And the cluster validation result is all right. But after disconnecting node"node A" from the SAN storage, the disk failed which belongs to the node "node A", and cannot be bringed online unless I manually switch it to the other node "node B". The error information is "0x8007174b failed to bring cluster disk online".
In the other hand, after rebooting node "node A", the cluster disk will failover to the node "node B" aultomatically without any error.
I have installed the recommended hotfixes and updates for window server 2012-based failover cluster, but the problem still exists.
