  Yes, it can be done and your original data should be available as the the hard disk still have the meta-data related to the original VD from the controller.   If a similar VD is configured  with the new hard drives, yes; once re-installed, the old hard drives will appear in a foreign configuration because they don't have association with the new VD. In this situation, you will have to import the configuration. Because the PERC 5/i controller supports disk roaming where you can move hard drives within different slots, you don't have to worry about disk numbering. The disks have the meta-data which is associated with the original VD. All you have to do is to put the original hard drives to the given slots and then proceed to import the foreign configuration. Let me know how it works out.
I have a perc 5/i in a poweredge server configured for raid 5. I have removed the original disks in the array and replaced with fresh disks.  now I want to put the original disk back in the array but I was also hoping to retain the data that is spread across the original disks. can this be done? when I put the original disks back in will I need to import the foreign configuration from them? when I removed the original disks I numbered them so I know what position they should be in if it matters. what are the steps to achieve this? if it's possible. thanks
