RE: Expand a virtual drive on a Dell Perc 6/i Raid 6?
This needs to be done one drive at a time. your RAID5 controller set can only function properly with the loss of one drive. This means that if you replace one drive your RAID array will be in a critical state. Replacing the drive with a larger capacity will then require you to reconfigure your VD aforementioned.
If you were to remove all 5 drives and replace them with larger drives the array has no way to understand the configuration changes since you have removed your parity drive. Put all 5 drives back and replace them one by one. Remove one, insert new and then reconfigure VD - repeat.
Never remove/replace more than one disk at a time in a RAID environment.
