On LPAR the read message buffer command should be executed on the path it was received on otherwise there is a chance that the CUIR assignment might be faulty and the wrong channel path is set online/offline. Fix by setting the path mask accordingly. On z/VM we might not be able to do I/O on this path but there it does not matter on which path the read message buffer command is executed. Therefor implement a retry with an open path mask. Signed-off-by: Stefan Haberland <sth@linux.vnet.ibm.com> |
