FCD
.-NOFCD-. >>-+-------+--------------------------------------------------->< '-FCD---'
Specifies whether FICON® director activities should be measured.
FICON director activity data is gathered by port address. There is no indication which system in the sysplex requested the I/O. Therefore, the data can be gathered on any system sharing the FICON directors. To avoid having duplicated data, you should set the FCD option on one system only.
Note: If you have specified the FCD option, please ensure
that you do not disable the gathering of FICON director statistics on that system by setting
STATS=NO in the IECIOSxx parmlib member. See the z/OS MVS Initialization and Tuning Reference. for
more information on the FICON STATS
parameter.
