Hi Jon,
SYSVIEW is reporting these devices as they have been defined by IBM.
The MVS command DEVSERV display also shows these devices as model 9 (33909).
In the case of a model 27 , the model 27 is a concept and not a physical device.
There is no model 27 DASD, it is a model 9 with additional tracks.
