MD3220 and Hyper-V CSV problem

Question

Hi, all...

I have the following cluster:

2 x R610, Windows Server 2008 R2, each with one 2-port 6Gb SAS HBA card

1 x MD3220 DAS with 2 controllers

I have set up the cluster fine (this is my 3rd using MD3xxx boxes), failover is working properly, etc. The problem arises when I try to use Cluster Shared Volume to set up a HA Virtual Machine. I can add a disk to Cluster Shared Volumes in the Cluster Manager, but it does not behave like a CSV should. It is only accessible from one node at a time.

Does anyone know if the MD32xx DAS models support CSVs? I have not found any info either way, but all the Microsoft documentation says that using a DAS should work fine. The only 'problem' I can find (using Google) with MD32xx DAS models and CSV is in reference to problems with VSS provider and backups. Any help or hints would be greatly appreciated.

Thanks!

Accessibility of a CSV volume from the non-owning node requires a heartbeat with IPv4 (or IPv6 I guess), the Microsoft client for networks, and File and Printer sharing enabled on the heartbeat network link.

Once both nodes can 'see' the disk (as reserved), the SAN plays no factor in CSV working or not.

Thanks a bunch, DEV MGR! That did it...instantly. It's a bit counter intuitive, because I'd read previous recommendations to disable MS Client and F+P Sharing on a heartbeat network to limit unnecessary traffic.

Have a great weekend!

You're welcome.

The disabling of the MS client and F+P sharing is valid for any type of cluster (Exchange, SQL, fileshare, etc), except a CSV (hyper-v) cluster.
