Adding Nodes to an existing federation

[J-Philippe]

Hello, I've plan to add 2 nodes to an existing federation of a 4 nodes stretched cluster.

For some reason I can't upgrade now the existing nodes to the same version of the new that I will receive as I believe that the 2 new nodes should be delivered in a higher simplivity version than the existing federation architecture (3.7.7). Should I use the deployement manager previously used for the initial installation or the new one that should be able to work ?

In any case (old or new deployement manager) I guess I will have to reset the 2 new nodes to downgrade the simplivity version to the same level of the existing node ? Using the old deployement manager shoud not downgrade the new node, I must perform a reset, am I right ?

Best regards,

Jean-Philippe

You are correct, the nodes will ship with 3.7.10. If you would like to join them to a 3.7.7 federation, you will have to factory reset the nodes to 3.7.7 with the included ".img" in the 3.7.7 files. I recommend contacting support and getting your federation up to 3.7.10 before the new nodes arrive. Besides getting more features, 3.7.10 fixes a major vulnerability found in previous software releases. 

If you stick with 3.7.7, you will have to use all 3.7.7 version of SimpliVity software; Arbiter, Deployment Manager, vCenter plugin and compatibile versions of vSphere products and firmwares. Please consult the interop guides on what version are compatible.

Hi Ben,

thanks for your answer, for sure the whole federation should be updated, I'm just facing a setback.

The interop matrix is ok in our actual situation.

One of the bigger reasons I found to upgrade to even 3.7.8 or 3.7.9, is that upgrading the OVC's can be done at the cluster level. I have been running our federation at two different levels for a couple weeks now so I can do more testing before rolling out to our production environment.

@J-Philippe  Yes you are correct. It would be great if you upgrade the current federation to 3.7.10 or 3.7.9.

This will help in overcoming the vulnerabilities of 3.7.7. Also doing a factory rest of new node is not recommended because supplied firmwares with new nodes are latest which might be incompatible with OVC Release 3.7.7
