Vista - Hyper-v Cluster

I have found some documents explaining how to set up clustering in Hyper-v
but this is for clustering the host servers. These docs talk about shared
iSCSI disks.

I would like to set up clustering, for test purposes, in a single Hyper-V
server - so would like to cluster the guest machines so I can test things
like failover clustering and Exchange 2007 clustering.

I know this could be done in Virtual Server but can it still be done in
Hyper-V ?

Thanks

Yes, but you need to use iSCSI for shared disks inside the child machines in
that case (assuming you're talking Server 2k8 guests, since you're saying
Exchange 2k7.)

Hi - thanks for the reply.

Sorry - after reading my original question, I don't think I was clear what I
was asking.

As I said, I had found documents relating to using iSCSI for the shared
storage in Hyper-V, but this was relating to failing over the hosts as well.

I wanted to know if clustering could be done in one box like Virtual Server
could, with no extra external storage. I want to familiarise myself with
clustering in W2008 and Exch2007 but don't have the hardware to set up extra
storage.

Thanks

No, it can't. BUT if you get yourself an iSCSI software package, you can do
it by creating an iSCSI server out of a basic Windows Server. Server 2k8
doesn't do clustering the same way as Server 2k3, and you can't use the
hyper-v SCSI disk (VHD) type for clustering. It's a change in the
clustering requirements for Server 2k8.

I was more than a little disappointed myself when I set up a SCSI disk and
was unable to select it as clustered storage.
I find this odd as an SCSI device *should* be capable of multiple mounting
at hardware level (by definition it's part of the SCSI language set.)
It's hardly an SCSI device if it doesn't support this...we must be missing
something.

Yeah, I was annoyed at the time, but it's been nearly 3 years now and I'm
over it. There are perfectly adequate iSCSI solutions out there. Use one
of them.

Step-by-step guide to creating an iSCSI target machine in Hyper-V using
Openfiler (Opensource Freeware)
http://searchstorage.techtarget.com....rosoft-Hyper-V

The most recent version of Openfiler has had some layout changes to the web
interface used in the walk-through but it's more or less the same process.
Be sure to scroll to the bottom of web-pages as some vital features (like
"create partition") lurk there.

Although 2008 can mount an OpenFiler volume it does not support SCSI-3
Persistant Reservations so it can't be managed by the Failover Clustering
service.
The freeware version of StarWind supports 2 nodes for cluster testing which
is OK for basic qarum based clustering.
Still need to find something suitable for Majority Node Set clusters (need a
minumum of 3 nodes for that.)

This is due to the change in clustering for Windows 2008 and above that
requires SCSI-3 Persistent Reservation support. Parallel SCSI does not
support this feature and that is what the SCSI emulator emulates.
As has been noted earlier, iSCSI is the preferred solution for guest
clustering.

You must admit though, it makes the virtual SCSI device type quite useless
though, may as well just offer virtual IDE type devices.
Maybe they will fix it later but for now it's a white elephant.
StarWind iSCSI seems to work fine though if you load it on the Hyper-V host
server using an image file device so at least it's not a complete dead end.
