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. Rescanning the controller will clear the
drive error status if the condition no longer exists.
