Hello Bill, >Do you have multiple channels going to the same control unit? You didn't >say. For example, does channel 10/11 go to one control unit and channel >12/13 go to another?
This is what the IOCDS looks like: CHPID PATH=(CSS(0),10),SHARED,PARTITION=((L6,L7),(=)), * SWITCH=01,PCHID=16C,TYPE=CNC CHPID PATH=(CSS(0),11),SHARED,PARTITION=((L6,L7),(=)), * SWITCH=01,PCHID=17C,TYPE=CNC CHPID PATH=(CSS(0),12),SHARED,PARTITION=((L6,L7),(=)), * SWITCH=02,PCHID=16D,TYPE=CNC CHPID PATH=(CSS(0),13),SHARED,PARTITION=((L6,L7),(=)), * SWITCH=02,PCHID=1EC,TYPE=CNC CNTLUNIT CUNUMBER=3300,PATH=((CSS(0),04,06,10,11)), * UNITADD=((00,256)),LINK=((CSS(0),84,A7,B1,41)),CUADD=3, * UNIT=3390 CNTLUNIT CUNUMBER=3301,PATH=((CSS(0),12,13)), * UNITADD=((00,256)),LINK=((CSS(0),AB,2F)),CUADD=3, * UNIT=3390 IODEVICE ADDRESS=(3300,145),CUNUMBR=3300,3301),STADET=Y,UNIT=3390 So I'd say yes, CU 3300 and 3301. But, does it matter? What would be the difference in either case? >Also, you can make DDR ignore a volser depending on how you invoke it. I know. But that does not change the fact that it did check the volser (and DDR had to check it), reported a volser and then wrote on a different disk. Regards, Berry.
