ICP550A dddd, INT REQ, CC=3/NO PATH AVAILABLE

Explanation

Before reading from an input device or writing to an output device, IOCP received a not-operational condition code (code 3) on the path specified. In the message, dddd indicates the device address or number.

System action

IOCP waits for the operator to:
  1. Correct the entry or make the path available.
  2. Try the operation again.

Operator response

  1. If the entry for the device was incorrectly specified on the frame, correct the entry and try the operation again.
  2. If the path is not available, turn on the path to the device (such as setting the channel or control unit switch) and try the operation again.
  3. If the path cannot be made available, run IOCP again using another device or path.
