In a routine failover to nodeB for Exchange 2007, all of the exchagne resources failed. Moved back to node A and all but one resource came back online and one database store failed to mount.Cluster error was: This action was not complete....cluster resource could not be brought up online by the resource monitor.EMC errors: Event ID 9518 Error Starting Storage group...Storage Group Intialization of Jet FailedEvent ID 1011 RPCcall to service failed to bring the cluster resource online failedand of course we cannot mount the database, because the resources won't start. Any thoughts?

Did you get a chance to have a look into this http://social.technet.microsoft.com/Forums/en-US/exchangesvravailabilityandisasterrecovery/thread/5f979140-c454-4346-8d9e-b0a9b820c1acRaj

Thanks that was helpful - we needed the dependencies on the storage group.
