I have to convert raid dp back to raid 4, which I have some aggrs, vols, luns and data on it. So do I lost my data after converting from raid dp to raid 4 ? I'm using cluster data ontap 8
When you change an aggregate's RAID level from RAID-DP to RAID4, the extra parity disks are converted to spares. In addition, the raidsize option is changed.
So normally it does'nt affect data consistency.
