Selection[0]: 7
The Cache Dirty flag on the indicated LUN is cleared, and the LUN is assigned to the current SP. In a dual SP environment, this parameter will only be accepted on the SP that is the default owner of the LUN. The LUN will then be available, but will contain inconsistent data. Some data blocks that have been acknowledged to the host have having been written will in face be unmodified. It is the customer's responsibility to perform whatever data recovery or repair operations are needed by the customer's application.
