Data access to any of the corresponding virtual disk or caching its partitions may lead to data corruption.

To obtain the values for controller ID and virtual disk ID, type `omreport storage controller` to display the controller IDs and then type `omreport storage vdisk controller=ID` to display the IDs for the virtual disks attached to the controller.
