Hello, Running exchange 2003 and windows 2003. I need to perform off-line defrags of 4 separate storage groups. If you dismount one, do you have to dismount all of them? Meaning can I be running the defrag on one storage group and give folks access to the store group that is not having the ESEutil run against it?
