NSX-T 2.5.1 Segmet Uninitialized

Jump to solution

Hello Everyone!

I am facing an issue, i can create everything on the Advanced Networking and Security tab, everything works perfectly, but when i changed to the Simplyfied UI and I've created a Segment it tells me: Uninitialized.

I've created a separated Edge, and Edge Cluster for the T0 GW, also created a separated Transport Zone too.

The NSX-T version is 2.5.1 all the three managers work well. I have tested the Advanced N&S with a working PKS deployment.There are 4 transport nodes, in a Shared Edge and Compute deployment.

Is there anybody who had seen this problem?

Kind Regards,

KaBalint

Im sorry, so the TZ means a vlan-tz, which needed on the edge to the uplink. Because on the uplink i wanted to set up a vlan tag, and on the port group which is connected to the edge was a trunk pg.

Anyway the shut down (all the three NSX-TManagers at the same time) and a turn on solved the problem.

Thanks for your help!

If you don't create a T0/T1 in the policy-based UI then you won't be able to utilize the logical segment.

I have created a T0/T1 GW too on the Policy Based UI. Those gw-s are up with green dot, but when i connect them to the segment it show up an exclamation mark with realization error, doesnt matter it is a downlink, or an external link.

You may need to check your transport nodes and ensure there are no issues. Sounds like there's a problem either at the edge or one or more of the nodes.

I think all of the nodes work well, because on the advanced ui, i can create everything, and all of the configurations work well.

Anyway thanks for your advice, these are all good ideas!

Are you sure you have host TNs with the necessary TZ? When you say you created a new TZ you would have to associate it with your host TNs. Realization errors usually occur if NSX manager doesn't have the necessary resource to provision the segment.

So then the cause was like I suspected: Something in one or more of the hosts was in an inconsistent state. A reboot can often fix these things like you've found. The fact that you shut them all down simultaneously shouldn't have made a difference.

When i restarted the nsx managers one-by-one did not help, thus this was my last chance to shutdown all of the managers, and it worked.

Oh so you shut down all of the manager appliances. Ok, that must have been something else then. Like a database replication/consistency issue.
