IEE507D
SHOULD ACTIVE DEVICES HAVE I/O TERMINATED? REPLY NO OR YES

Explanation

The operator replied CONTINUE in response to messages IEE100E and IEE131D. That reply told the system that a CONFIG CHP(xx),OFFLINE command with the FORCE option should continue, even though the channel being removed is the last path to one or more devices.

This message asks the operator whether or not those devices should be boxed, which means:
  • I/O on the device is ended.
  • Any new I/O requests result in permanent I/O errors.
  • No new allocations are done for the device.
  • If the device was online, it is marked pending offline. A pending offline device goes offline when these conditions occur, in this order:
    1. The device is no longer allocated to any job.
    2. Allocation can get the necessary resources to process the request.

    If the device was offline, it remains offline.

System action

The system waits for the operator to reply.

Operator response

Do one of the following:
  • Reply NO to allow the current I/O to complete and to keep allocated devices, teleprocessing devices, and devices the system is using online.

    Generally, reply NO if you want to discontinue the request to configure a channel path offline.

  • Reply YES to mark the devices pending offline and purge all I/O.

    Generally, reply YES if you must prevent I/O from being enqueued to the devices, or you must prevent the device from being allocated.

    Reply YES only when you must get a channel offline regardless of what happens to ongoing I/O over the channel. This reply can cause data to be damaged or lost.
