Problems failing an Exchange 2007 cluster

The move-clusteredmailboxserver cmdlet can move the cluster "too fast".  It is designed to get the services shutdown as quickly as possible and transfer control of the cluster to the other node.  To shut things down more deliberately, use the following cmdlets:

• Get-MailboxServer | Get-MailboxDatabase  | Dismount-Database -Verbose
• Stop-ClusteredMailboxServer clustername -StopReason "This is my reason" -Verbose
• Move-ClusteredMailboxServer clustername -TargetMachine node2 -MoveComment "Move Comment" -Verbose
• Start-ClusteredMailboxServer clustername -Verbose

Before performing any cluster failover commands, you should use the get-storagegroupcopystatus cmdlet (http://technet.microsoft.com/en-us/library/aa997246(EXCHG.80).aspx).
