Revision ba4ba8a69dcb446450b5ddeca48a7bd15783f4c2 authored by Peter Oberparleiter on 27 July 2006, 12:00:23 UTC, committed by Martin Schwidefsky on 27 July 2006, 12:00:23 UTC
In special conditions where a subchannel rejects the HALT I/O- instruction with a busy indication (cc 2), I/O may stall. I/O request termination logic retries HALT I/O indefinitely because it expects HALT I/O to alter the subchannel status which is not true when cc 2 is returned. In case of a busy indication, try CLEAR I/O instruction immediately. Signed-off-by: Peter Oberparleiter <peter.oberparleiter@de.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
