We use win2012 for clustering with a SAN for different customers
We use two channels ISCSI mpio to connect to the SAN.
The ISCSI is redundant network.
The Cluster network is redundant.
When we disconnect on of the channels we noticed that the communication with the SAN goes via the cluster management network through the other HOST and not via the redundant ISCSI channel. (We see it at some customers, not all)
What can be the reason?
