Great. So the ones that are NOT dismounted can be accessed while the one is being defragged. Correct? _____ From: exchangelist-bounce@xxxxxxxxxxxxx [mailto:exchangelist-bounce@xxxxxxxxxxxxx] On Behalf Of Greg Herzog Sent: Wednesday, April 04, 2007 5:24 PM To: exchangelist@xxxxxxxxxxxxx Subject: [ExchangeList] Re: Performing an off-line defrag You only have to dismount one database at a time. i.e, you have 4 storage groups, with 4 databases in each, you do NOT need to dismount all the databases within a storage group. So out of the 16 databases, just one at a time.

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?
