Hi,
I have a multi site Hyper-V cluster 2008 R2, 3 hosts in site A and 3 hosts in site B connected by a 10GBps link. The hosts are each in a Dell blade chassis.
We have a problem on the Heartbeat/ CSV network in site A that affects two of the hosts.
We currently do not have any VM's running on these two nodes, we do on the other node however.
To troubleshoot this issue, we need to change the port channel (Blade chassis networking) of the CSV VLAN so it's CSVB NIC will drop for approx 3 seconds.
I'm hoping someone can advise when this happens will VM's on the running host be affected?
So in simple terms, host 6 in a cluster has 15 VM's running, it's CSV NIC will drop for 3 seconds, will this cause all VM's to crash or should it cope with this CSV network drop?
Thaqnks
Alan
