Problems Associated With Using The Same Physical Disks For Both Redundant And Non-Redundant Virtual Disks
When creating virtual disks, you should avoid using the same physical disks for both redundant and nonredundant virtual disks. This applies to all controllers. Using the same physical disks for both redundant and nonredundant virtual disks can result in unexpected behavior including data loss.
NOTE: SAS controllers
do not allow you to create redundant and nonredundant virtual disks
on the same set of physical disks.
