What is the easiest way to upgrade an existing mirror to 2 new bigger drives? I currently have a production server that is a Dell Poweredge 840 with a SAS5/IR Controller card that has 4 Sata ports with only 2 being used by 2 250GB sata drives. I run Zimbra Server on this unit and the 250z are filling up quickly so I purchased 2 750GB sata drives from Dell and now I am stumped on how to smoothly and easily transfer the existing mirror to these 2 new drives. Dell is of know help with this even at Enterprise level (Silver). There has got to be a way to do this given that anybody who has a mirror config server would have to upgrade at some point to bigger drives? Any help from the Experts would be totally 100% graciously appreciated.
