4 Run sfupdate to update these NICs (command options may vary):
# sfupdate ‐‐ write ‐‐ yes ‐‐ force
5 Run the command to unbind the interfaces again. There will be failures
reported because some of the interfaces are not bound:
# for bdf in $(lspci ‐ D ‐ d 1924: | awk '{ print $1 }'); do \

echo ‐ n ${bdf}\ > /sys/bus/pci/devices/${bdf}/driver/unbind; done
6 Repeat the process for the other interfaces (0000:04:00.x; 0000:83:00.x and
0000:84:00.x) doing so in pairs until all the NICs have been upgraded.
7 Rebind all interfaces, doing so en ‐ mass and ignoring errors from those already
bound:
# for bdf in $(lspci ‐ D ‐ d 1924: | awk '{ print $1 }'); do \

echo ‐ n ${bdf}\ > /sys/bus/pci/drivers/sfc/bind; done
Alternatively reload the sfc driver:
# onload_tool reload
or:
# modprobe ‐ r sfc

# modprobe sfc
8 Run
ifconfig ‐ a
again to find that all the interfaces are reported and all have
been firmware upgraded without having to physically touch the server or
change the kernel.
Sfupdate: SLES 11 Limitation
Due to limitations in SLES 11 using kernel versions prior to 2.6.27.54 it is necessary
to reboot the server after running the sfupdate utility to upgrade server firmware.
