<strong>FICON</strong> channels can be identified from the TYPE column; their type begins with FC:<br />
type FC indicates a native <strong>FICON</strong> channel;<br />
type FC_S indicates a native <strong>FICON</strong> channel connected to a switch or director<br />
type FCV indicates a <strong>FICON</strong> bridge channel which connects to an ESCON control unit via a<br />
bridge card in a 9032 model 5 ESCON director. <strong>FICON</strong> <strong>Express2</strong> channels do not support<br />
FCV mode.<br />
The ID column is the <strong>Channel</strong> Path ID or CHPID number. CHPID 95 is displayed in Figure<br />
