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
lpfc_max_scsicmpl_time Uses command completion time to control queue depth. The
units are in milliseconds.
The minimum value is 0 (default). The maximum value is 6000. Yes
lpfc_multi_ring_rctl When lpfc_multi_ring_support is enabled, identifies the routing
control (R_CTL) for the additional ring configuration.
The minimum value is 1. The maximum value is 255. The default
value is 4. Yes
lpfc_multi_ring_support Determines the number of primary SLI rings over which to spread
IOCB entries.
The minimum value is 1 (default). The maximum value is 2. Yes
lpfc_multi_ring_type When lpfc_multi_ring_support is enabled, identifies the TYPE of
the additional ring configuration.
The minimum value is 1. The maximum value is 255. The default
value is 5 (LLC/SNAP). Yes
lpfc_restrict_login When enabled, restricts VPorts login to remote initiators.
The enabled value is 1 (default). The disabled value is 0. No
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. Yes
lpfc_sg_seg_cnt Controls the scatter/gather maximum segment count passed to
the FC and FCoE driver. This variable is applicable per SCSI
command.
For LPe12000, LPe11000, and LP11000 adapters, the minimum
value is 64 (default), and the maximum value is 4096.
For OneConnect and LPe16000 and LPe15000 series adapters,
the minimum value is 64 (default), and the maximum value is
510. Yes

lpfc_sli_mode For LPe12000, LPe11000, and LP11000 adapters, this parameter
allows you to force the SLI mode requested by the adapter
driver. The possible values are:
• 0 = Auto-select (default)
• 2 = SLI-2
• 3 = SLI-3
Note: For OneConnect and LPe16000 and LPe15000 series
adapters, this parameter is not applicable and has no
effect.
