Note: If an asterisk (*) appears next to the status of a unit, there is an error on one of the drives in the unit. This feature provides a diagnostic capability for potential problem drives. The error may not be a repeated error, and may be caused by an ECC error, SMART failure, or a device error. To see if this error condition still exists, rescan the controller; rescanning will clear the drive error status if the condition no longer exists. Identify.
