If I currently have a two disk hardware mirror or RAID 1 can I migrate the data from them to a RAID 5 array by adding 4 more drives? Do I need all 6 drives in the array or can I make one of them hot swappable in case something goes wrong? Will it fail over automatically? I am using a Windows Server 2008 and a Perc3 RAID card. I have all 146GB Seagate drives.

Thanks. We'll let you know when a new response is added.

Not usually. You have to rebuild the array into a RAID 5 array which will probably require that the RAID 1 array be destroyed before the disks can be used in a new RAID 5 array.

You can setup a hot spare when you build a new RAID 5 array.

    Backup the disks..... kill the raid (this will wipe the disks) Then restore the data
