Updating System Software - Kontron CP6924-1 User Manual

A complete software release for the CP6924-1 consists of the two files (example package-names):
•
"CP6924-system-ipv6-BETA-1.00.pkg" or "CP6924-system-l2only-BETA-1.00.pkg" (depending on the board type)
•
"CP6924-ipmi-BETA-1.00.hpm" (firmware package for the IPMI firmware)
In the following, the CLI commands to setup and copy System SW images and the CLI commands necessary to perform
upgrades are described. As the commands are the very same for both system packages mentioned above, only the com-
mands for the l2only version are described.
The CLI commands described below are executed in the privileged mode of the CLI hierarchy, which is entered by executing
the 'enable' command. Please refer to the "CP6924-1 CLI Reference Manual" for more information regarding the CLI com-
mands and the way to use them.

Updating System Software

The Software image is updated using the CLI. The following precautions are met to ensure a reliable and failsafe update pro-
cedure:
•
Two independent system partitions, containing active system and backup system software. Active system is stored in
flash mtd partitions mtd0-4, backup system is a verbatim copy of active system and is stored in flash partition mtd5
as a whole. This allows flash recovery from the redundant system in case that update fails due to power loss or similar
errors.
The system update package (CP6924-system-l2onlyres-<release>.pkg) contains an image of bootloader, kernel, root
filesystem as well as a MD5 checksum file for consistency check.
When performing an update, the software package is loaded from a remote TFTP server. A software update of the CP6924 is
done by performing the following steps:
1.
Copy the required file onto your tftp server. Rename the file to a shorter name (max. 31 characters):
root@tftp-serv:# mv CP6924-system-l2only-BETA-1.00.pkg CP6924-system-l2only.pkg
2.
Log in to the privileged exec mode of the CLI of the CP6924-1
3.
Prepare network access of the system
(Ethernet Fabric) # serviceport protocol dhcp
4.
Copy system image into the active image of the flash memory
(Ethernet Fabric) #copy tftp://192.168.50.154/CP6924-system-l2only.pkg active
(Ethernet Fabric) #
5.
Check availability of valid boot image in active image using the command 'show bootvar'
(Ethernet Fabric) #show bootvar
