If a drive is replaced it must be the same size and configuration.
Stripe sets are the most critical here.
You can not change a drive with a larger drive, set up the stripe set and format with the larger drive. The same holds true with a RAID that has a bootable partition on the first drive, you must setup the partition again. Our support people can help here, feel free to contact us.
