dqfull-throttle-up-
time
Controller
Specific
1 0 30 Yes Time interval (seconds) to
increment LUN queue depth.
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.
enable-auth Controller
Specific
0 0 1 Yes This driver property specifies
if the DH-CHAP is enabled or
not. When set to 1, also set up
two other driver properties
such as auth-cfgparms and
auth-keys. When set to 0, DH-
CHAP support is disabled and
auth-cfgparms and auth-keys
are ignored. Any per HBA
instance setup, for example,
lpfcX-enable-auth=1, 0 will
overwrite the value set by
enable-auth.
