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.

Physical Disk Is Offline Or Displays An Error Status
A physical disk may display an error status if it has been damaged, is offline, or was a member of a virtual
disk that has been deleted or initialized. The following actions may resolve the error condition:
• If a user has changed the status to Offline, then return the disk to Online status by executing the
Online disk task.
• Rescan the controller. This action updates the status of storage objects attached to the controller. If
the error status was caused by deleting or initializing a virtual disk, rescanning the controller should
resolve this problem.
• Investigate whether there are any cables, enclosure, or controller problems preventing the disk from
communicating with the controller. If you find a problem and resolve it, you may need to rescan the
controller to return the disk to Online or Ready status. If the disk does not return to Online or Ready
status, reboot the system.
• If the disk is damaged, replace it.
