Vista - High availability with FC-HBA

We are trying to test a dual Hyper-V configuration and its failover
capabilities. Each blade is running Hyper-V/Windows 2008(Core). They are
connected via a 4GB fiberchannel HBA to a FC-switch and then to our SAN. Each
Hyper-V also has two GB-Enet cards.

For our test, we have a two VM (Vista) running on the first server with
their VHD files on the SAN on LUN #12. Only the first CORE has that disk
enabled and mapped to a volume (V but the second CORE does see the disk.

Can you point me towards a process to set up an environment where I can
easily shutdown one of the VMs on Core #1 and start it on Core #2. The risk,
obviously, is that both Cores have to talk to the same LUN on the same SAN.

Thanks in advance for any help.

Welcome to Windows Clustering.

Yes, you can cluster Core.

You need to first create a quorum disk and cluster the two core nodes. Then
you can bring the LUNs into the cluster management as cluster storage
resources. Clustering manages multi-connected storage and handles the
failover/failback implementation.

If you want more than one VM per LUN and you want them to fail over
independently, you need to run Windows 2008 R2. If you don't mind them
failing over together and always being on the same host, then you can stay
with Windows 2008
