You could just try the various commands available to see what you get. D IOS,FICON D M=SWITCH(ss) D M=DEV(aaaa,(cc)),ROUTE=BOTH D M=DEV(aaaa,(cc)),LINKINFO=COMPARE
For the D M=DEV. These are examples as there are a few options for various things so check out the manual. Note you must obviously specify a single path hence the inclusion of the CHPID (cc). However, do a D M=DEV(aaaa) to get a list of all the CHPIDs available.
