Hardware RAID Guidelines
 | Caution - When you create a RAID volume using the on-board disk controllers, all data currently on the disks you include in the volume will be lost. |
The following points are important to understand when configuring RAID volumes on a server:
Before configuring and using RAID disk volumes on a server, ensure that you have installed the latest SRU or patches available for your OS. Review the most recent product notes provided for your server for further guidance in keeping your OS up to date.
Volume migration (that is, relocating all RAID volume disk members from one server to another) is not supported. If you must perform this operation, contact your authorized Oracle service provider.
