All lpfc dynamic parameters are read/write using sysfs.
lpfc_max_luns 256 1 32768 Specifies the maximum
number of LUN IDs per
target. A value of 20 means
LUN IDs from 0 to 19 are
valid. The SCSI layer will
scan each target until it
reaches the specified LUN
ID.
Yes
lpfc_multi_ring_support 1 1 2 Determines the number of
primary SLI rings over
which to spread IOCB
entries.
No
lpfc_poll 0 1= poll wiith
interrupts enabled
3 = poll and disable
FCP ring interrupts
Sets FCP ring polling mode
control. Yes
lpfc_poll_tmo 10 1 255 Milliseconds the driver
waits between polling FCP
ring interrupts.
Yes
