Re: SD-WAN manager refuses to start nms services

stevesmith741 · ‎08-01-2024

Hi community, I've beed beating my head against a brick wall for days now. Over it. I have installed controller nodes in a CML2 lab following the procedure at https://www.youtube.com/watch?v=CQruni5x8Vk and despite many attempts I cannot get the nms services to start on the manager node. Outputs from nms requests are below - these were taken 2 hours after booting. All the search results when I look for these conditions just talk about ensuring there is enough RAM (32GB) and a second data volume has been created for the database (I have - 250GB, formatted, very slow process). VPN 0 is configured per the advice in the video and all controllers can ping each other. There must surely be some useful debugging tips out there? Am I unique in being unable to get this to work!

Hi Steve, this is Eric from SDWAN TAC Team.

I understand you have issues with the NMS services of your lab.

What is your vManage version?
Is this a brand new deployment?
Was it working before? If so, what was the version that was running before?
Follow the below process:
- Access vshell by doing:
  vshell
- Verify the logs:

tail -f /var/log/nms/vmanage-server.log

Try to bring the services up by doing:
request nms all restart
Capture any error log you observe in the command line.
Share them with me.

Hi Eric, thanks for coming to my aid! The details you requested are copied below.

Not sure if any of these outputs could suggest a cause:

This one shows up once a minute roughly -

vmanage:/var/log$ tail nms/vmanage-runutils.log
13-Aug-2024 12:40:25,598 AEST INFO [] [EncryptionFacility] (main) || CryptoKey store initialized
13-Aug-2024 12:40:25,605 AEST ERROR [] [Multiplexer] (main) || Failed to generate password for UC user

This one seems to be do with the vbond session:

Hi @stevesmith741

I had the same problem during my study lab. The first one was about the CPU and vRAM resources that wasn't enough. You can check this on the follow link: https://www.cisco.com/c/en/us/td/docs/routers/sdwan/release/notes/compatibility-and-server-recommendations/server-requirements.html

The second one occured when I did a vManage upgrade. I solved by creating a new vm and performing the restore vManage by utilization of a configuration-db backup. You can check this on the follow link: https://www.cisco.com/c/en/us/support/docs/routers/sd-wan/220305-standalone-vmanage-disaster-recovery.html

Best regards

stevesmith741 · ‎08-12-2024

Thanks Samuel, I've checked the resources allocated and I have 32G RAM as recommended and 16 vCPUs as recommended. The only variation was in disk allocated. I had 256G where 512 is recommended. Upping that now and will advise if anything changes.

Steve

stevesmith741 · ‎08-12-2024

Changed disk size to 512. No change in behaviour so far.

stevesmith741 · ‎08-13-2024

Ok, now I have a working manager again. I gave up on the one supplied with the cml2 reference platform as nothing seems to get it working. I decided to go all the way with a complete node definition from scratch following instructions at https://ether-net.com/2020/08/24/ccie-6-how-to-lab-cisco-sd-wan-in-cml2/. I chose to download the stable release recommended on CCO (20.9) rather than 20.13. So now I have manager running 20.9, controller and orchestrator both on 20.13. Sounds like trouble! Not sure what the path of least resistance to go forward with is. Downgrade of orchestrator and controller to 20.9, or upgrade of manager to 20.13? Or maybe just hope the two versions play nicely in the schoolyard!

stevesmith741 · ‎08-15-2024

I begin to wonder whether it's actually possible to build a stable cisco sd-wan environment. After finally breaking through and getting the manager component running and being able to access the GUI, now I find the GUI has stopped responding, for no apparent reason, despite not having made any changes to it or the other controllers. I am pretty much on the verge of giving up. the product seems to be extremely fussy and unstable, the documentation is woeful, there are too many ways to run it up and the instructions for various processes fail unless your environment is setup in a very specific manner. clearly if you don't have access to the TAC you shouldn't be bothering to try and run up this environment. it's taken weeks out of my life and I think I'm no closer than I was at the beginning!
