As z Systems environments have grown, and configurations have become more complex, FICON fabric issues can result in unacceptable I/O service times.  Various RMF/SMF records may show several abnormalities, but it typically has been very problematic to identify a single root cause for the issue(s), especially if the issue is in the FICON SAN fabric.  FICON CUP Diagnostics helps solve this challenge.
