7. Verify that your images and configuration are set correctly.
8. Reload the switch.
After following these steps, you should end up with the following results:
• Primary image will hold the new software image you want to install (for example,
K.15.01.0031)
• Secondary image will hold the image you are currently running (for example, K.14.47)
• Primary image will boot with Config1 (config file corresponding to new software version—in
this example, K.15.01.0031)
• Secondary image will boot with Config2* (config file corresponding to previous software
version—in this example, K.14.47)
* The current config file must be copied to Config2, or you will be unable to revert if the need
arises.
NOTE: You might opt to use a different methodology in which the new software will be installed
as the secondary and not the primary image, in which case you would use the commands boot
system flash secondary, and/or boot set-default flash secondary to change the location of the
default boot. However, since you will still need to take precautions to allow you to revert to your
previous configuration, We strongly recommend that you follow the methods that are proposed in
our update process. This will ensure that you can use our proposed roll back procedures should
the need arise.
Detailed steps
The following detailed steps shows how to update the switch software from an existing version to
a significant new version (in the example provided here, from version K.14.47 to version
K.15.01.0031).
1. Download the latest software image to your TFTP server from the HP networking web site:
www.hp.com/networking/support
2. Save your current configuration (Config1) to backup configuration file (Config2).
a. Before copying the config, verify the current state of your system using the show version,
show flash and show config files commands. For example:
Switch1# show version
