Upgrading L1 Firmware

007-4377-002

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.

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.
