The status elements are updated only on EOP and not every SGL element. This section describes the status updates and suggests use of UserHandle field to associate multiple SRC or DST-Q elements to a single STAS or STAD-Q element update.


TIP:   The DMA does not use the UserHandle or UserID fields. To utilize the UserHandle field, you can implement the same relationships entirely in software layer and use the UserHandle and UserID fields in your custom environment.
