dqfull-throttle-up-
inc
Controller
Specific
1 0 128 Yes Amount to increment LUN
queue depth each time. This
driver property causes the
LPFC driver to decrement a
LUN’s queue depth, if a queue
full condition is received from
the target. The queue depth
will be decremented down to a
minimum of 1. The variables
dqfull-throttle-up-inc and
dqfull-throttle-up-time are
used to restore the queue
depth back to the original. The
dqfull-throttle-up-time driver
property defines a time, in
seconds, that is used to tell
when to increase the current
queue depth. If the current
queue depth isn't equal to the
lun-queue-depth, and the
driver stop_send_io flag is
equal to 0 for that device,
increment the current queue
depth by dqfull-throttle-up-inc
(don't exceed the lun-queue-
depth). So, if both driver
properties are set to 1, then
the driver increments the
current queue depth once per
second until it hits the lun-
queue-depth. The only other
way to restore the queue
depth (besides rebooting),
back to the original LUN
throttle, is by running the
command
/opt/lpfc/resetqdepth X. This
will restore the LUN throttle of
all LUNs for HBA X back to
the original value.
