Emulex Drivers for VMware ESXi User Guide
3.2.7 FC Driver Module Parameters
Table 4 lists the FC driver module parameters, their descriptions, and their corresponding values in ESXi native mode.
Dynamic parameters do not require a system reboot for changes to take effect.
NOTE: Refer to the VMware documentation for quick boot instructions.
Table 4: FC Driver Parameters
Module Parameter Description Values Comments
lpfc_compression_log Defines how often the
compression logs are written
(in seconds).
This parameter is dynamically
updated.
Default = 300
Min. = 5
Max.= 86,400
The driver uses this parameter to
periodically write status messages to the
vmkernel log. The messages provide state
analysis on the paths, targets, and adapter.
It differs from throttle in that the throttle stops
the driver from spamming the logs on a very
high frequency failure.
lpfc_delay_discovery Delays N_Port discovery when
the Clean Address bit is
cleared.
This parameter requires a
system reboot or quick boot.
Default = 0
Min. = 0
Max. = 1
When the parameter is set to 0, no delay is
added to the initial discovery.
When this parameter is set to 1, initial
N_Port discovery is delayed by RA_TOV
seconds when the Clean Address bit is
cleared in FLOGI/FDISC accept and the
FCID/Fabric name/Fabric port name is
changed.
lpfc_devloss_tmo The number of seconds the
driver holds I/O waiting for a
lost device to return.
This parameter is dynamically
updated.
Default = 10
Min. = 1
Max. = 255
—
lpfc_discovery_threads The maximum number of
Extended Link Service
commands that can be
outstanding during discovery.
This parameter requires a
system reboot or quick boot.
Default = 32
Min. = 1
Max. = 64
—
lpfc_enable_auth Enables or disables DH-CHAP
authentication.
This parameter is dynamically
updated.
0 = Disable
(default)
1 = Enable
NOTE: DH-CHAP and Dynamic D_Port are
mutually exclusive. If both features are
enabled simultaneously, warning messages
will result. You must either disable
DH-CHAP using the lpfc_enable_auth
parameter, or disable Dynamic D_Port using
the Emulex HBA Manager application.
lpfc_enable_bb_credit_recove
ry
Toggles the Buffer-to-Buffer
Credit Recovery feature.
This parameter requires a
system reboot or quick boot.
0 = Disable
1 = Enable
(default)
Not supported on LPe12000-series
adapters.
lpfc_enable_da_id Controls the DA_ID common
transport command.
Unregisters objects with the
fabric nameserver.
0 = Disable
1 = Enable
(default)
