I have a filer which is connected in ISCSI to a Hyper-Cluster.
Each node of Hyper-V has one NIC, in LAN which can join de ISCSI's filer.
When I launch a manual Takeover on Netapp, the cluster loose the ISCSI and the Virtual Machines shutdown. It doesn't reconnect to the ISCSI.
I also have a second ISCSI connected to an other server which contains data. When I run a takeover, the ISCSI shutdown but it reconnects after 40 seconds. It seems that the issue appears only for Hyper-V clusters.
