This document provides the steps necessary to perform Dynamic RAID Migration (DRM) for a given VDisk, using Common Array Manager (CAM) or the sscs CLI (Command Line).
The requirements for this are as follows:
- There can be only one VDisk in a Pool, if you are changing the level at the pool level.
- There can only a single volume in a VDisk, if you are changing the level at the volume level.
- Migrations to a RAID 1+0 require an even number of drives.
- The volume sizes remain unchanged, so a migration from a RAID 5+1 to 3+3 would
require that the volumes can be contained within the space of 3 drives of the
original 5+1 VDisk.
