Dell CERC Raid 5 Problems
Hi all,
Having problems with a Dell PE 830 and the CERC raid controller.
Current setup was 3 x 80GB Maxtor drives in a RAID 5. We were called in to upgrade the 3 x 1TB Drives.
Process we followed, imaged using acronis true image (verified the image) backed up data using their backup veritas 9.1 (verified backup).
Took 1 80GB drive out and replaced with 1TB. Initiliased the disk however was not given the option to rebuild the array using the new drive. Could only add it as a Global hotspare.
Replaced original 80GB drive, now server 2003 won't boot. Bluescreen before login prompt. Raid status changed from degraded to failed. I can't imagine one of the other drives failing although it may be possible, both are reporting OK on smart status.
We have now built a new array using the 3 x 1TB and are restoring the image using Acronis. This has failed even though we verified the backup.
Any one got any hints as to things to try?
Are we able to put the original drives back in or are we at a complete DR point?
Thanks

server 2003 would not boot at all, bsod with 2 drives (2x80gb), 3 drives (3x80gb) and 3 drivers (2x80gb, 1x1TB)

This was the route we went down, although just one array with the 3 x 1TB drives. Restored the acronis image and then 11 hours to restore the veritas backup so all in all a long day and night but all was working. Thanks for the help guys.
If you replace one by one 80GB disk by a 1TB disk you´ll end up with 160GB in RAID5 where 2TB were possible.
