Hyper V 2008 R2 Stand Alone Failover Cluster IP change

Hey,
I have 3 computers configured with Hyper V 2008 R2 Stand alone server. I
initially configured them with DHCP addresses, and now would like to change
them to static IP's. Whats the process to do this, without breaking
anything?

Hi James,

this depends on your hyper-v network implementation. But generally ff you
want to change the IP of your host this is totally independent from your VMs
network connectivity. To make it a bit clear, you can change the IP of the
parent parition without having an impact on the VMs network connectivity.
This applies only if you will stay on the same physical network segment
(VLAN), but if the VLAN / subnet changes as well then of course the VM will
loose the connectivity and you need to set them new IP adresses as well.

Also think about, hyper-v networks should have at minimum 2 network cards
(best practice). 1 x parent parition (Host) management interface and min. 1
x DEDICATED for hyper-v only.
More details around Hyper-V Networking and best practices can be found here

THanks for the info
I basically just want to change from the servers, so instead of getting
their IPs through DHCP they will get a static IP (same subnet, vlan, etc)
Right now each node (node1, node2, and node3) are getting DHCP IP's, and the
cluster HyperVCluster, is also getting a DHCP IP.

So Do I just need to change each node to a static IP? This won't break the
cluster? How about the Cluster, how do I change its IP to static?

Just to clarify, each Node does have multiple nics
One for cluster communication/remote management (this is the one I want to
change) , one reserved for the VM's and 2 connected to SAN.

Normally in a well configured cluster environment a short network
connectivity timeout should be covered by different network routes (a.e.
Heartbeat) for cluster comm to stay up. I'm not sure if you MUST change ALL
nodes to static IP to be supported. But I would change node-by-node from
DHCP to static IPs. Ideally you move first all ressources to a other node
:-) Also think about DNS here, if you provide any services other than VMs
(client access points) they will possibly run into an timeout. And all
active connections on this mgmt adapter will be resetted (RDP). At the end
you should run a cluster validation wizard to stay compliant with your
configuration ;-)
