This read-create RowStatus object controls creation and deletion of a VSAN-to-WWN mapping row, and per the desc it cannot be set to active unless the corresponding wwnmVsanWwn column already holds a valid WWN value. It enforces that an admin must supply the actual WWN before the row can be brought into service. For example, an admin attempting to activate a new VSAN-WWN row without first writing a valid wwnmVsanWwn value would find the row rejected by wwnmVsanWwnRowStatus until that value is properly set.
