From 47593bfa1056d306fde067b28dd8617009be4121 Mon Sep 17 00:00:00 2001 From: Sebastian Ott Date: Tue, 31 Mar 2009 19:16:05 +0200 Subject: [S390] cio: introduce notifier for boxed state If a ccw device did not respond in time during internal io, we set it into boxed state. With this patch we have the following behaviour: * the ccw driver will get a notification if the device was online and goes into the boxed state * if the device was disconnected and got boxed nothing special is to be done (it will be handled in reprobing later) * if the device got boxed while initial sensing it will be unregistered Signed-off-by: Sebastian Ott Signed-off-by: Martin Schwidefsky --- drivers/s390/scsi/zfcp_ccw.c | 5 +++++ 1 file changed, 5 insertions(+) (limited to 'drivers/s390/scsi') diff --git a/drivers/s390/scsi/zfcp_ccw.c b/drivers/s390/scsi/zfcp_ccw.c index 1fe1e2eda512..cfb0dcb6e3ff 100644 --- a/drivers/s390/scsi/zfcp_ccw.c +++ b/drivers/s390/scsi/zfcp_ccw.c @@ -176,6 +176,11 @@ static int zfcp_ccw_notify(struct ccw_device *ccw_device, int event) zfcp_erp_adapter_reopen(adapter, ZFCP_STATUS_COMMON_ERP_FAILED, "ccnoti4", NULL); break; + case CIO_BOXED: + dev_warn(&adapter->ccw_device->dev, + "The ccw device did not respond in time.\n"); + zfcp_erp_adapter_shutdown(adapter, 0, "ccnoti5", NULL); + break; } return 1; } -- cgit v1.2.3
