I am in the process of migrating data from our existing FAS2040 to a new FAS2240-4, some of the volumes I need to migrate are fairly large (1.5Tb+) so I am thinking the best way to do this is to create a SnapMirror between the two and replicate the volume(s). All the volumes contain LUNs accessed via FC rather than CIFS etc. As a new comer to this I have been testing this by creating a test volume/LUN and then SnapMirroring this to the new FAS2240. My question is relating to the best way to present this SnapMirrored LUN to the servers (which are all Windows 2003/2008 systems with SnapDrive installed). I can break the mirror using System Manager and then configure the initiators on the LUN and the server does then see the LUN however I wanted to check this is the "best practise" way of presenting the LUN to the server as I know it can all be done via SnapDrive which can perform the breaking off of the SnapMirror as part of connecting the disk? Sorry if the question isnt clear, I am just looking for some guidance on how you guys would proceed in this task!
