Emulex Drivers for Linux User Guide
lpfc_irq_chann Defines the number of EQs (and MSI-X vectors)
requested.
The default value is 0. A value of 0 means that the driver
automatically determines a recommended amount of
EQs, MSI-X vectors, and lpfc_hdw_queue to allocate
based on system resources. This value is limited by the
lesser of the number of CPUs and lpfc_hdw_queue.
NOTE: Depending on system resources, a default value
of 0 may overwrite any values set for
lpfc_hdw_queue.This is to ensure proper driver
recommended settings between hardware queues, EQs,
and MSI-X vectors.

lpfc_lun_queue_depth Specifies the default maximum number of commands
sent to a single logical unit (disk drive).
The minimum value is 1. The maximum value is 512. The
default value is 64.
The value of lpfc_lun_queue_depth is dependent on
the max_xri value received. The max_xri value might
vary per adapter type.
NOTE: This parameter can be dynamically changed
using the Emulex HBA Manager application.
Yes All Driver reload
lpfc_max_luns Specifies the highest available LUN ID that is valid, per
target. For example, a value of 19 means that LUN IDs
from 0 to 19 are valid for the target. The SCSI layer scans
each target until it reaches this specified LUN ID.
The minimum value is 0. The maximum value is 65535.
The default value is 255.
Yes All Driver reload
lpfc_max_scsicmpl_time Uses the specified command completion time to control
queue depth. The units are in milliseconds.
The minimum value is 0 (default). The maximum value is
6000.
Yes All Driver reload
lpfc_nvmet_mrq Configures the allocation of multi-receive queues (NVMe
target mode only). The default value is 0 (the driver sets
the appropriate value). The maximum value is 16.

lpfc_ras_fwlog_func Configures the function on which firmware logging
support is enabled.
The minimum value is 0 (default). The maximum value is
7.
The default is logging enabled on Function 0.

lpfc_restrict_login When enabled, restricts the vPorts login to remote
initiators.
The enabled value is 1 (default). The disabled value is 0.
No All Driver reload
lpfc_scan_down When enabled, selects the scan down method (scanning
the AL_PA from high to low) to assign a SCSI ID.
The enabled value is 1 (default). The disabled value is 0.
