FICON with CUP activation is designed to provide in-band management of the supported SAN b-type switch and director products by System Automation for OS/390 or z/OS from IBM 9672 Parallel Enterprise G5 and G6 servers, and IBM zSeries 900 and 990 servers.To enable in-band management on multiple switches and directors, each chassis must be configured with the appropriate FICON CUP feature. This support is designed to provide a single point of control for managing connectivity in active FICON I/O configurations. System Automation for OS/390 or z/OS can now concurrently manage IBM 9032 ESCON Directors as well as supported SAN b-type switch and director products with FICON.
