This display was originally created to help customers tune their OSA read buffers. Since they could only tune the values to 16, 32, or 64...there wasn't a need to display the 32-63 buffers, since you couldn't increase the value any more. OSA read buffers being full is not an indication of whether the card is approaching max capacity. OSA read buffers fill when TPF cannot service the OSA cards (call OSA polling) in a timely manner. For example during system dumps.
Determining if more cards are needed should be done by analyzing OSA statistics and OSA utilization. The utilization of the card is displayed in TPF data reduction in the Channel Path Utilization Report for the CHIPID of the card and that is what should be used to determine maximum capacity of the card. Or using OSA/SF which is a statistical tool for OSA that runs on z/OS or z/VM.
We recently added warning messages when buffers fill (PJ42415), and seeing these warnings increase over time is a better way to determine if some action needs to be taken. This request is being rejected as we see little to no value in showing the additional buffers.
