The EVA3000 2C2D can be expanded out to a 2C4D by adding 2 additional 5414R disk shelves.<BR /><BR />If you look around the forms a bit, there are some posts pertaining to adding shelves and procedures, best practices, etc..<BR /><BR /><BR />Basicly, it is best to plan for some downtime.... shut the unit down, install/connect the shelves, power it back up. Once your shelves are online and confirmed working, I would then add your disks.<BR /><BR /><BR />Steven Tue, 26 Oct 2004 10:57:32 GMT https://community.hpe.com/t5/disk-enclosures/adding-disk-to-eva-3000/m-p/3408177#M14066 Steven Clementi 2004-10-26T10:57:32Z https://community.hpe.com/t5/disk-enclosures/adding-disk-to-eva-3000/m-p/3408178#M14067 ... and note that since 1. september there are new rules for SOM licensing.
