Revert Previous ArubaOS Version Using CLI

Hi Guys,

 

I just like to ask some help. My client has Aruba 3400 Conrtoller with ArubaOS 6.1 version. We will upgrade it to ArubaOS 6.4. My client is asking what if the upgrade fails, can we still boot it to ArubaOS 6.1, and how using CLI? Thank you in advance.

Hi,

 

If you run "show image version" you can see your 2 boot partitions and what ArubaOS is on each.

 

It'll show something like this:

 

#show image version
----------------------------------
Partition : 0:0 (/dev/hda1) **Default boot**
Software Version : ArubaOS 6.4.0.0 (Digitally Signed - Production Build)
Build number : 38241
Label : 38241
Built on : Thu May 2 20:40:35 PDT 2013
----------------------------------
Partition : 0:1 (/dev/hda2)
Software Version : ArubaOS 6.1 (Digitally Signed - Production Build)
Build number : 39611
Label : 39611
Built on : Tue Aug 27 08:26:28 PDT 2013

 

Above you can see that 6.4 is on partition 0 and 6.1 is on partition 1.

 

To boot from the 6.1 image (assuming you didn't upgrade that partition) as per the output from my example above you could run, "boot system partition 1".

 

All of this is in the release notes Upgrade Procedure section for each and every ArubaOS.

 

Release notes.

 

Cheers

James

Hey, you can boot into the older firmware by changing the controller to boot in the partition you required. For example if you look at the output below, we can see there is 2x partitions each with a different version.

 

 

(001) #show image version 
----------------------------------
Partition               : 0:0 (/dev/mtdblock9) **Default boot**
Software Version        : ArubaOS 6.4.2.5 (Digitally Signed - Production Build)
Build number            : 48774
Label                   : 48774
Built on                : Tue Feb 24 22:02:57 PST 2015
----------------------------------
Partition               : 0:1 (/dev/mtdblock10)
Software Version        : ArubaOS 6.1.3.4 (Digitally Signed - Production Build)
Build number            : 34587
Label                   : 34587
Built on                : Mon Jul 23 15:48:34 PDT 2012

We can see that the controller is running currently from partition 0:0 as this has the **Default boot** next to it.

 

 

If you wish to boot into the other partition, change the boot statement 0:1

 

#boot system partition 1

And then review the output of 

#show image version

 Once you are happy for the controller to boot from the required partition then simply reboot the controller using the #reload command
