i have created 2 node, and configured and the following error appear me in Eventview in Virtual Server 2005 when i start both node at the same time. "node1"encountered an error when attempting to use one of its virtual hard disks. The virtual hard disk "Cocuments and SettingsAll UsersDocumentsShared Virtual Machinessharedarray.vhd" attached to primary channel (1) of "node1" 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. i followed the steps of this page>http://www.sql-server-performance.com/installing_sql_clustering_virtual_server1.asp about to add hard drive named sharedarray.vhd in both node. Plz help me about failover cluster with sql server.
