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?

Regards,

Kevin

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.
