I have two node servers with SAN storage. Each node have RHEL 6.9 with HA and the partition are mapped from the storage using fiber cables with clustered resources.
The thing is when the two nodes are working everything is fine. When one node is completely removed and the other node rebooted the clustered service will not work if there is no ping to the other node with the managment port.
Then after starting the second node the cluster start ok.
Fencing are configured ok.
Dell emc R640
What is this? Misconfiguration??
