Problem Clustering Between Nexus Dashboard in Different Versions

[Domingos Silva]

Hello everyone,

I'm experiencing difficulties when trying to establish a cluster between three ND. My current situation is:

• 1 ND in version 3.0.1i
• 2 ND in version 2.3.2d

Problem 1: Cluster Doesn't Form

My goal is to update everyone to the latest version, but before that, I'm trying to establish the cluster. I suspect that the difference in versions may be a problem.

To throw off the track, I tried to start the nodes of version 2.3.2d separately. The bootstrap  process happens, but the nodes are left with no progress in the cluster bring-up process.

Given this, I decided to try the re-image of the nodes, but without success. I'm using the following command to map the ISO:

C220-node/vmedia # map-www image http://192.168.254.254/nd-dk9.3.0.1i.iso

However, when checking the status of the mapping, I get the following error:

C220-node/vmedia # show mappings Volume Map-Status Drive-Type Remote-Share Remote-File Mount-Type image "ERROR: Local device ... CD http://192.168.254.254/ nd-dk9.3.0.1i.iso www

Doubts:

1. Does the difference in versions really prevent the formationv of the cluster or is there another possible cause?
2. How can I resolve this lock on the cluster?
3. Has anyone ever faced this error when mapping ISO to re-image? Are there any alternatives or configurations I should review?

Thank you in advance for your help!
