host is compatible with versions (<UNKNOWN>) and cannot join cluster

Latest response

Hello,

Fresh install of RHEV and using version 3.1. I have RHEV-M up and running, however, when I attempt to add our hypervisors (HP BL460c Gen8) I recieve the following error message "Host [servername] is compatible with versions (<UNKNOWN>) and cannot join Cluster POC-DEV-TEST which is set to version 3.1"

The hypervisors and management server are running a base install of RHEL 6.3. I am not using the rhev-h ISO to built the hypervisors. I'm pushing the hypervisor packages over from the management box. Everything seems to go well, but when the hypervisors come back up I receive the error message posted above. 

I opened a ticket early this morning, but have not heard back yet. Any ideas for troubleshooting in the mean time?

 

Thanks in advance,

Brian

Is sudo configured on the RHEL host you are trying to add?

What is the case number you opened this morning?

I guess the more appropriate question I should ask is, are you using a customized sudoers file?

Take a look at this KCS article: https://access.redhat.com/knowledge/solutions/292643 

While not a direct match, it could be you have something in your sudoers file that is not sympatico with vdsm.

Thanks for the article link. I'll read through it. We do use a custom/modified sudoers file. I was able to use this same type setup for a proof of concept, but with older hw and rhev 3.0. The case # is 00790272

That link must be to an internal article. I get access denied when trying to view.

Ah! Yes it is, my apologies.

I located your case and am looking at your logs now. Will follow up with you there.

Thanks,
Jeff
