Does Channel Gateway X (CGX) support multipath FICON?
Yes. CGX supports multiple FICON paths within a Channel Gateway unit, providing failover and load balancing capabilities. In conjunction with error recovery on the mainframe, switch/directors, and CGX, failed or inactivated ports will allow the remaining FICON paths to continue processing without affecting the jobs. Error recovery performance will be dependent on the mainframe platform and OS. For example, a z10 will significantly outperform a z890 with respect to its failover and recovery process.
