P2V of a windows cluster to vmware

Hi Experts,

I have several old WIN2008 cluster running in my environment.
Also I have running VMWARE vSphere 5.5 with 3 hosts.
The storage of the VM Datastores are connected to my new NETAPP storage.

I want to virtulize all my servers to VMWARE with P2V.

My old servers with WIN2008 are connected to my old HP SAN MSA2000 over fibre channel.
But my hosts have no connectivity to the old MSA2000.

Can you help me to find a way to virtulize my all clusters with P2V ?

VMware Converter, works in the current OS, so it will capture/clone the information, e.g. disks it detects, and then converts that information and sends it to ESXi and creates a VM.

The hosts do not need connectivity to the old MSA2000.

Hi,

I know the data is then copied to my new vm.
But what about my cluster configuration on it ?

this is a Windows failover Cluster ?

if it is, you will have to re-create the Failover Cluster using other technology e.g. iSCSI RDMs

So you are going to have to think about what service this is, what cluster service this provides, and may be easier to rebuild a new Failover Cluster using your NetApp using either RAW LUNs (FC or iSCSI) or Software iSCSI.

OR, break the Cluster, evict of of the nodes, and P2V the remaining non cluster nodes.

Do you need a Failover Cluster to be completely virtual, if you do, create from new.

Yes it is a windows failover cluster.

Now my VM´s are connected to a NETAPP NAS via NFS.
Can I also use ISCSI in paralell ?

Yes, you can use FC and iSCSI.

ok now I understand.
What is recommended ?
I have a physical cluster for my file server with WIN2008.

Now I want to virtulize the machine, but a windows cluster on a vmware cluster makes no sense right ?
Is it enough when I break the mirror, and then make p2v ?
The vmware cluster is enough right ?
For the data I have to be sure the backup is running.

Or is a LUN via ISCSI recommended ?

Correct, break the cluster and P2V it.

You need to decide, do you need a Microsoft Failover Cluster for the service it provides...

VMware HA and VMware DRS will give a single VM availability...

but what happens when you need to patch the Windows VM?

Can you have downtime ?

Hi, I have one more question about this issue.

When I break the cluster and P2V the exch Server, what about my CLuster IP ?

Can I setup the Cluster IP when I P2V the machine ?

Because after P2V, the data moved from the old LUN into my new VM.
When I now activate the cluster, the resources are not available.

Which is the best P2V path in this case ?

You cannot expect to P2V an existing cluster physical cluster, toy a virtual environment, and have it all working.

But, you can break the cluster, and stop clustering, and move all the data and resources.

If you still want to have a cluster, you will have to perform, and build a new Cluster, and Migrate the resources.

When I P2V the first node, then all settings are migrated into my VM, also the failover cluster from windows, right ?
But it will not work yet, because of the resources.

But when I setup all LUNs and NICS, then I can run again this cluster , right ?

For my Exchange Cluster I have this plan:

1. stop the cluster
2. stop the EXCH databases
3. P2V the machine
4. unistall old HP software
5. check IP settings and CLuster network
6. connect all LUNs and copy data to the LUNs
7. check the correct drive letters for the LUNs
8. start the cluster with one node
9. P2V the second node

What do you think about it ?

Scrap it, I would not even attempt it.

Build a new Exchange Server, Cluster, Infrastructure etc

and Migrate mailboxes to it!

Much quicker, and Supported, in what you are attempting to do.
