Table 3: LPFC.conf Parameters (Continued)

Property Name	Scope	Default	Min	Max	Dynamic	Comments
dqfull-throttle-up-	Controller	1	0	30	Yes	Time interval (seconds) to
time	Specific					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	0	0	1	Yes	This driver property specifies
	Specific					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.
