It "probably" will work, assuming that the OS disk is not configured as a RAID or array member in the RAID cards' BIOS. Meaning, if you're using the disk on the controller purely in a "JBOD" fashion, yes, it should work. > I'm curious to know if the array could be migrated just as easily, or if > I should listen to my instinct and count on bumping into > incompatibilities due to proprietary implementations. I can absolutely guarantee you that you will lose access to all of your data once you plug those 3 disks into another controller. You need to back up all of your data from the RAID-5 array using something like rsync, cpdup, or dump, move the disks over to the non-RAID controller, format them (in whatever fashion you want), and then restore the backup. -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
