ICP301I DEVICE xxxx HAS EXCEEDED THE MAXIMUM NUMBER OF I/O DEVICES ALLOWED FOR SUBCHANNEL SET z IN CSS y

Explanation

Device number xxxx has exceeded the maximum number of I/O devices supported in subchannel set z in CSS y. For a dynamic-capable IOCDS, IOCP enforces the MAXDEV keyword value specified for subchannel set z in CSS y. If no value was specified or if the IOCDS is not a dynamic-capable, IOCP enforces the subchannel set device limit that the CPC supports. See Machine limits to check the device limits the CPC supports.

System action

IOCP continues to validate and check the syntax of the remaining statements. However, it does not generate an IOCDS and it does not produce configuration reports.

Programmer response

Do one or both of the following:
  • Reduce the number of I/O devices in the configuration for the subchannel set for the CSS
  • For a dynamic-capable IOCDS, increase the value specified with the MAXDEV keyword for the subchannel set for the CSS up to the device limit the CPC supports.
