I’ve been testing upgrading a 3600 controller from 3.3.3.10 to 6.1.3.1. Although the interim image step is different than the documentation states for 6.1.3.1, I was told that this works better. I will first upgrade to 5.0.4.5, verify all works correctly, then upgrade to 6.1.3.1.
I have tested this once on a spare 3600, and it seemed to have gone well. There are no AP’s attached but I was comparing the configs after each upgrade step which seems better than nothing to me at this point.
I have a couple of questions here. Currently my 3600 looks like this after the upgrade:
(Aruba3600) #show image version
----------------------------------
Partition : 0:0 (/dev/hda1) **Default boot**
Software Version : ArubaOS 6.1.3.1 (Digitally Signed - Production Build)
Build number : 32786
Label : 32786
Built on : Tue Mar 13 00:28:42 PDT 2012
----------------------------------
Partition : 0:1 (/dev/hda2)
Software Version : ArubaOS 5.0.4.5 (Digitally Signed - Production Build)
Build number : 32431
Label : 32431
Built on : Sat Feb 18 17:56:01 PST 2012
What I wanted to do is to restore the flash backup I took before I started any of this when it was still on 3.3.3.10 so I could test one more time. I copied that flashbackup.tar.gz back to the flash and did a restore, then a reload. During the reload it says “Upgrading configuration from version 3.3 to 6.1.” and once it is done I am back to being fully upgraded. It is acting like it just did an upgrade straight from 3.3.3.10 to 6.1.3.1. If I do a show image version directly after I restore the flash it still looks like the above example.
What exactly does a “backup flash” back up?
I am thinking that in order for me to get back to step one I need to put 3.3.3.10 into partition 1, then restore the flash?
Also in another post related to an upgrade I noticed these commands “show ap image version” and “apflash all local backup-partition”. I don’t have any RAP’s only AP’s, but when I do a show ap image version I see that they are all on the same code level as the controller. As part of my upgrade will the AP’s also be upgraded? What extra steps should I add? Here are the steps I put together.
VIA CLI
- Prepare backups
- Enter backup flash command
- Copy backup and default.cfg to TFTP
- Execute these commands from the CLI, capture to a text file for comparison after upgrade
i. Show AP database
ii. Show AP active
- Install AOS
- Use show image version to check which partition to load the new image to.
- Use the copy command to load the new image onto the controller
i. copy tftp: 10.8.0.20 ArubaOS_MMC_5.0.4.5_32431 system: partition 1
ii. Execute the show image version command to verify the new image is loaded
Reload the controller. Be sure to reboot BOTH controllers at the same time
- Verify installation
- Use show version to make sure on the version
- Execute these commands to make sure the AP's all come up. Once they are up compare the output with the original with a tool like WinMerge
i. Execute the show ap database command to determine if your APs are up and ready to accept clients.
ii. Execute show ap active to view the up and running APs.
- Redo steps 1-3 for upgrade to 6.1.3.1
