Upgrading L2 Firmware

007-4653-001
You can update individual bricks by replacing all with a rack and slot number:
$> /usr/cpu/firmware/sysco/flashsc --12 10.1.1.1
/usr/cpu/firmware/sysco/l1.bin 1.19
This updates only the brick in rack 1, slot 19.
The L2 firmware consists of two parts:
• Boot image
• Kernel image
Typically, you will upgrade the firmware through the network connection from the
SGIconsole to the L2 controller:
$> /usr/cpu/firmware/sysco/flashsc --12 10.1.1.1
/usr/cpu/firmware/sysco/l2.bin local
Once this command is executed, you must power-cycle the L2 controller to run the new
image. You can also do this with the L2 command reboot_l2.
Unlike the L1 controller, if the L2 update fails, a second image is not available to use as a
back-up copy. However, the L2 controller will not run the kernel image if it is not valid.
If the L2 update fails, you can update it through its console port:
$> /usr/cpu/firmware/sysco/flashsc --l2recover /usr/cpu/firmware/sysco
/l2.bin <device>
Output will indicate that the firmware image is being erased and then rewritten. The
flash image is quite large (almost 2 MB), so updating the flash image takes several
minutes. You must power-cycle the L2 controller to run the new image. You can also do
this with the L2 command reboot_l2.
