Lab : Upgrading the Cyclades firmware

Upgrading the Cyclades Firmware

These instructions may vary from release to release. There is usually a README.FIRST and an upgrade_nnn.txt file which explain the details for upgrading from release to release.

Determining the current firmware version

To determine the current firmware version issue the command

cat /proc/version

This will show the current Linux version as well as the AlterPath-ACS32-Linux version. Here is an example:

[root@curator root]# cat /proc/version Linux version 2.4.17_mvl21-linuxplanet (root@genesis) (gcc version 2.95.3 20010315 (release/MontaVista)) #1 Mon Dec 8 16:11:48 PST 2003 AlterPath-ACS32-Linux V_2.1.5-1 (Dec/08/03) [root@curator root]#

Determining what upgrade version(s) are available

Go to ftp://ftp.cyclades.com/pub/cyclades/alterpath/acs/released/ where all the released/supported versions of the firmware are located. Determine whether there are released versions more recent than the currently installed version.

If there is a newer release, go to the directory for that release and review the README.FIRST file and the the upgrade_version.txt file. These files will have further instructions on completing the upgrade.

Note that these files should be considered more reliable than these instructions!!

Before performing the upgrade

Make sure to read the upgrade_version.txt file before upgrading the firmware for any special instructions for configuration changes that are required.

Performing the upgrade

These instructions are an example from the 2.2.0.1 release.

1. Telnet or ssh to your ACS and login as root.
2. Go to the /proc/flash directory. # cd /proc/flash
3. Establish a ftp connection to the Cyclades ftp site and login as anonymous (using your e-mail address as password). # ftp ftp.cyclades.com username: anonymous password: you@email.address
4. Once connected, go to the ACS 2.2.0.1 firmware directory. ftp> cd /pub/cyclades/alterpath/acs/released/V_2.2.0.1/
5. Make sure your ftp transfer mode is set to binary, just type "bin" at the ftp prompt. ftp> bin
6. Download the new firmware overwriting the current one. ftp> get zImage_acs_2201.bin zImage
7. Once the download is complete, quit from the ftp connection and reboot your ACS ftp> quit # reboot
8. Your ACS will be running now the new firmware version 2.2.0.1. In order to keep your current configuration, please read the upgrade_220_1.txt text file and follow the upgrade instructions. ftp://ftp.cyclades.com/pub/cyclades/alterpath/acs/released/V_2.2.0.1/upgrade_220_1.txt
9. Verify you are running the expected version: # cat /proc/version

Configuration updates

After upgrading the firmware, follow the instructions in the upgrade_version.txt file for manual configuration steps that need to be done.

After updating configuration files

Don't forget to invoke the new configuration and save the configuration files to flash memory by issuing the following commands:

signal_ras hup saveconf
