Hello guys, I have a question about Hyper-v clustering subject.
I have 3 notes Hyper-v cluster, with 6 NICS.
1 NIC For Management, 192.x.x.x
2 NICs for SAN communication, 10.x.x.x. both are in the same 10.x.x.x subnet 255.0.0.0
1 NIC for the Heartbeat 172.x.x.x 255.255.0.0
2 NICs Just for VMs assignments.
All these connections are connected in a 2 switch stack. Cables are alternated accordantly to have redundancy. node1 to SAN on Nic1>switch1. node1 to SAN on Nic2> switch2. All three have the same configuraton.
Last week we had a failure on switch 1 and we lost connection on all VMs. I checked and under the Cluster manager, we are missing one NIC on each server dedicated for the SAN communication. I guess that explains why we lost connection to the VMs. The SAN never went down because it has two controllers and it was working on the second switch.
Cluster and failovers are working fine with live migrations, but as long as we have failures on any node, but when we had a power failure on the first switch we lost connection the vms. That tells me that the connection from the host to the vhd on the SAN was lost. All three nodes lost connection to the SAN.
My question is, how can I add or make the second NIC on each NODE to join the group of “SAN Connect” group. In this group, only one NIC with 10.x.x.x shows in there. Do you guys know if I need to assign another subnet to the second NIC in order to make it available on the cluster? Exam: 11.x.x.x.if so, I will have to reconfigure the SAN to include the 10.x.x.x and 11.x.x.x. Thank you in advance and any help will be very appreciated.
