I am upgrading my Perc 5 to a Perc 5i (allegedly lets me have hot spares and power management). When I put the 5i card in and connect the drives, it does not recognise the previous RAID configuration. Import foreign disks is grayed out. How do I get this new card installed without having to rebuild this server. If I rebuild the array do I lose all data?

You might check with the manufacturer for guidance/support on this. – user48838 Aug 27 '11 at 23:59

Dell has instructions to do this. They're located here:

It doesn't look like these two cards are as related as they seem; they don't play nice together. Creating a disk image with Acronis and then restoring was the only option that worked.
