When that happens the driver becomes dependent on the kernel to figure out if the adapter is misbehaving. This might take some time (when the adapter is idle). The driver currently has support to restart/recover the controller when it fails, and decreasing the time interval will help. Fixed by decreasing check interval from 24 hours to 1 minute Signed-off-by: Raghava Aditya Renukunta Reviewed-by: David Carroll --- drivers/scsi/aacraid/aachba.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/drivers/scsi/aacraid/aachba.c b/drivers/scsi/aacraid/aachba.c index 98d4ffd..3ede50f 100644 --- a/drivers/scsi/aacraid/aachba.c +++ b/drivers/scsi/aacraid/aachba.c @@ -311,7 +311,7 @@ module_param(update_interval, int, S_IRUGO|S_IWUSR); MODULE_PARM_DESC(update_interval, "Interval in seconds between time sync" " updates issued to adapter."); -int check_interval = 24 * 60 * 60; +int check_interval = 60; module_param(check_interval, int, S_IRUGO|S_IWUSR); MODULE_PARM_DESC(check_interval, "Interval in seconds between adapter health" " checks."); -- 2.7.4
