The default lun queue depth by the driver has been 30 for many years. However, this value, when used with more recent hardware, has actually throttled some tests that concentrate io on a lun. Increase the default lun queue depth to 64. Queue full handling, reported by the target, remains in effect and unchanged.

Removed min, max, default from comment. No need to state when they are clearly specified in the macro. --- drivers/scsi/lpfc/lpfc_attr.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/drivers/scsi/lpfc/lpfc_attr.c b/drivers/scsi/lpfc/lpfc_attr.c index 4317c9ce7eca..63affb2269e7 100644 --- a/drivers/scsi/lpfc/lpfc_attr.c +++ b/drivers/scsi/lpfc/lpfc_attr.c @@ -3868,9 +3868,9 @@ LPFC_VPORT_ATTR_R(enable_da_id, 1, 0, 1, /* # lun_queue_depth: This parameter is used to limit the number of outstanding -# commands per FCP LUN.
