The Configuration wizard enables you to change the location of a Storage Group or database that you had associated with a LUN, or local disk, if you want to change your configuration plan.
The list of available drives changes as you make choices that rule out other choices.
If the Exchange system file path for a Storage Group is on the database LUN (placed for a previous version of SnapManager), and then you use the Configuration wizard to reconfigure a database path of the Storage Group or file path of the transaction log, then the Configuration wizard automatically moves the system file path to the same LUN as the file path of the transaction log.
