Upgrading L1 Firmware
The L1 firmware is currently distributed as part of the
snxsc_firmware
package. To
determine which version of the package is installed on your system console, enter the
following command:
$> rpm -q snxsc_firmware
If the package is installed, the full package name (including the revision) is returned:
snxsc_firmware-1.18.3-1
The L1 firmware binary and the utilities used to update it are stored in
/usr/cpu/firmware/sysco
.
Upgrading L1 Firmware
Note that a USB-to-Ethernet adapter connection or SGIconsole option is required to
execute the commands described in this section. See “Console Hardware Requirements”
on page 24 and Figure 2-2 on page 19 for descriptions of the hardware connections.
The L1 firmware consists of three parts:
•
Boot image
•
A image
•
B image
At boot time, the boot image validates the A and B image, and if it is not instructed
otherwise, it executes the newer of the two images. Because the L1 is running one of the
two images, the image not in use is the image that will be overwritten when the firmware
is upgraded. You need to re-boot any L1 update either by power-cycling the brick or by
using the L1 command
reboot_l1
.
Typically, you will upgrade the firmware through the network connection from the
SGIconsole to the L1:
$> /usr/cpu/firmware/sysco/flashsc --12 10.1.1.1 -p
/usr/cpu/firmware/sysco/l1.bin all
This updates all the bricks in the system. The
-p
at the end of the first line instructs the
firmware to flash the proms in parallel.
