This doesn't seem to make sense from a hardware perspective. Based on your two posts the only channel path working is CHPID 12--10, 11 and 13 were/are attached to the wrong directors. What other control units is CHPID 12 attached to? What do the control unit(s) for volume VM2076 look like?

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.
