Emulex 3.4 user manual LPFC.conf Parameters

Table 3: LPFC.conf Parameters (Continued)

Property Name	Scope	Default	Min	Max	Dynamic	Comments
fdmi-on	Global	0	0	2	No	This driver property controls
						the FDMI capability of the
						LPFC driver. If set to 0
						(default), FDMI is disabled. A
						value of 1 enables FDMI
						without registration of host
						name port attribute, while a
						value of 2 enables FDMI with
						registration of host name port
						attribute.
ip-class	Controller	3	2	2	Yes	FC is capable of transmitting
	Specific					IP data in Class2 or Class 3.
						The LPFC driver defaults to
						using Class 3 transmission.
link-speed	Controller	0	0=auto select		No	Sets link speed.
	Specific		1=1G
			2=2G
			4=4G
			8=8G
linkdown-tmo	Controller	30	0	255	Yes	This variable controls how
	Specific					long the driver will hold I/O
						(0 - 255 seconds) after the link
						becomes inaccessible. When
						this timer expires, all I/O
						waiting to be serviced is
						aborted. For instance, FCP
						commands will be returned
						back to the target driver with a
						failure. The lower the value,
						the quicker the driver will fail
						commands back to the upper
						levels. There is a trade-off
						here: small values risk
						retrying the commands when
						the link is bouncing; large
						values risk delaying the
						failover in a fault tolerant
						environment. linkdown-tmo
						works in conjunction with
						nodev-tmo. I/O will fail when
						either of the two timers
						expires.
log-only	Controller	1	0	1	Yes	When set to 1, log messages
	Specific					are only logged to syslog.
						When set to 0, log messages
						are also printed on the
						console.
