The HMC or SE has the ability to do this, or used to so a ESCON port could be sparred over to another port. That way you did not have to code it in the IOCP.

I'm currently looking in the "System z Input/Output Configuration Program User's Guide for ICP IOCP" but I'm not sure what to look for. I keep getting this error when trying to add another channel: CHPID PCHID=160,PATH=(60),TYPE=CNC,SHARED CHPID PCHID=161,PATH=(61),TYPE=CNC,SHARED CHPID PCHID=162,PATH=(62),TYPE=CNC,SHARED CHPID PCHID=163,PATH=(63),TYPE=CNC,SHARED CHPID PCHID=166,PATH=(66),TYPE=CNC,SHARED CHPID PCHID=170,PATH=(70),TYPE=CNC,SHARED CHPID PCHID=171,PATH=(71),TYPE=CNC,SHARED CHPID PCHID=175,PATH=(75),TYPE=CNC,SHARED CHPID PCHID=176,PATH=(76),TYPE=CNC,SHARED CNTLUNIT CUNUMBR=0C00,PATH=(60,61,62,63,66,70,71,75,76),UNIT=3990, X UNITADD=((00,256)),CUADD=0 *ICP ICP115I DELIMITER ERROR, EXPECT RIGHT PARENTHESIS - ,76),UNI CNTLUNIT CUNUMBR=0D00,PATH=(60,61,62,63,66,70,71,75,76),UNIT=3990, X UNITADD=((00,256)),CUADD=1 *ICP ICP115I DELIMITER ERROR, EXPECT RIGHT PARENTHESIS - ,76),UNI CNTLUNIT CUNUMBR=0E00,PATH=(60,61,62,63,66,70,71,75,76),UNIT=3990, X UNITADD=((00,256)),CUADD=2 *ICP ICP115I DELIMITER ERROR, EXPECT RIGHT PARENTHESIS - ,76),UNI CNTLUNIT CUNUMBR=0F00,PATH=(60,61,62,63,66,70,71,75,76),UNIT=3990, X UNITADD=((00,256)),CUADD=3 *ICP ICP115I DELIMITER ERROR, EXPECT RIGHT PARENTHESIS - ,76),UNI IODEVICE ADDRESS=(0D00,256),CUNUMBR=(0C00), X UNIT=3380,UNITADD=00 IODEVICE ADDRESS=(0E00,256),CUNUMBR=(0D00), X UNIT=3380,UNITADD=00 IODEVICE ADDRESS=(0F00,256),CUNUMBR=(0E00), X UNIT=3390,UNITADD=00 IODEVICE ADDRESS=(1000,256),CUNUMBR=(0F00), X UNIT=3390,UNITADD=00 The error message states: "IOCP expected a right parentheses as the first character of string xxxxxxxx. This error can occur if a keyword value contains too many characters or if more parameters than your CPC supports were specified." Is it possible to configure a spare channel for redundancy? Thanks for the help. Sherry E.
