Airwave Upgrade from 8.2.4 to 8.2.5.1

I recently went through the process of upgrading Airwave in my lab from 8.2.4 to 8.2.5.1. It was troublesome, to say the least. A fundamental change was introduced in versions from 8.2.4 onwards - full access to the Linux shell is no longer possible, with a text menu provided instead.

This is discussed at length in many posts; some of them are listed in "Other Related Material".

 

Backup!

With a virtual version of Airwave, taking a snapshot of the system with ESX is quick and easy, and provides one or more restore points in case things don't work out as planned.

Keep them dated and labelled properly, and remove them once the task is completed.


Get the file on the Airwave server
This is where the lack of root access became a problem for me, along with the limited options for file access.

Upgrade
Once the upgrade file is copied on to the Airwave server, the upgrade process should find it and run the upgrade!

My first attempt failed:

Upgrade script AMP-8.2.5.1-amp_upgrade was not found in local cache.
Upgrade package found in local cache.

However, the second attempt was successful! It took about 1hour 45min.

Upgrade from 8.2.4 to 8.2.5.1 is successful.

Version 8.2.5.1 provides some additional menu options too, and some of the upgrade issues are said to be ironed out.

Root Access
This process (from http://community.arubanetworks.com/t5/Network-Management/AirWave-8-2-4-NO-CLI/td-p/298005 ) would probably be fine - except the GRUB bootloader is also password protected! It may be possible to bypass the bootloader password as well, but I did not pursue this.

 

  1. Reboot the server with CTRL-ALT-DELETE.
  2. When the blue boot screen pops up (depending on what OS you have, you may have an AirWave logo or CentOS or another OS logo on this page), press "e" to edit the boot configuration.
  3. Move the cursor down to the line that starts with 'kernel', and press "e" again to edit that line
  4. Make sure you're at the end of the line, give a space and add the word "single" (without quotes) to the string, then hit
  5. Type 'b' to continue the boot process; you'll boot quickly into a shell without having to enter a password
  6. Use the 'passwd' command to enter and confirm a new password for the root user
  7. Write down the new password and keep it someplace safe.
  8. Add root acces back vi /etc/passwd
  9. change the first line to: root:x:0:0:root:/root:/bin/bash
  10. Use the 'reboot' command to reboot the server into full operations mode.
  11. Log back in and create new user so you can log in without root
