Hi!

I'm currently prepairing a SQL Server Cluster on Virtual Server 2005
according the documentation on
http://www.sql-server-performance.com/installing_sql_clustering_virtual_server1.asp

But when I've added the shared SCSI disk as described I can only start the
first node in the cluster.
When I want to start the second node I get the following error message from
Virtual Server 2005:

"SQLClusterNode2"encountered an error when attempting to use one of its
virtual hard disks.

"The virtual hard disk "D:\SQL Server 2005 Cluster\Shared
Data\SharedArray.vhd" for the slave device of IDE bus 1 of "SQLClusterNode2"
could not opened with read-write access. You need read-write access to the
virtual hard disk to boot a virtual machine. Another virtual machine or the
Virtual Disk Manager might be using this disk right now."

Any suggestions?

Thanks

Double check your steps against this -

Hi Rodney!

As far as I have seen from this article, I must configure the Cluster
Services on each node before I can use the shared disk?

Thanks

Correct! Microsoft clustering uses the shared nothing model.

Cheers,

Ah yes, you need to use virtual SCSI interfaces, not IDE for cluster
quorum disks. Virtual Server 2005 (and, indeed, real servers) won't
support running shared disks on an IDE bus. You're more than welcome to
try it though - I'm intrigued to see the results ;-)
