Sixothree, With that controller the only way for you to do it is to backup the data, then delete and recreate the Virtual Disk with the new larger drives. If you were to rebuild each drive with the larger drive it would designate the larger drive as the same size as the previous drives. Then once you rebuilt the final drive you can  create a new virtual disk with the left over space on the drive. The other issue you have is that you also can't migrate a Raid 5 to a Raid 10, you can only convert a Raid 5 to Raid 0,5, or 6 . So you would need to backup the data, delete and recreate the Virtual Disk, reinstall the OS, then restore the data. Let me know if this helps.
We have an R510 with SAS RAID-5 that I would like to upgrade with some larger/faster disks. I would like to migrate the volume to the new set of disks that will be in a RAID 10. Is this possible without too much trouble? Thanks in advance
