LUN
Any of the legacy DSFs can be used to access the I/O device. Care must be taken to prevent the simultaneous use of multiple DSFs for conflicting purposes. For example, two DSFs for the same LUN might be used for different volume or disk groups.
Agile view concepts
Starting with
Agile view I/O addressing logic looks like Figure 17.
