We want to upgrade the CPU in one node only in 3node cluster. Please guide us, how can we achieve this. Please send step by step instructions.
Just resurrecting this thread based on recent experience with one of our customers: Nutanix categorically do not support CPU upgrades on clusters that are under maintenance. This has been confirmed by the head of support.
I’ve just done this on my home CE cluster - just evacuate the node, shut down in the normal manner, swap out the CPU and bring it all back up again. Any VMs will need shutdown/restart on the new CPU to ‘see’ it though.
Looks like EVC equivalent on AHV is done automatically Living Migration Between Old and New Processors | Nutanix Community - but I didn’t need to worry as I was swapping out the same generation, just adding cores/GHz.
But anyway, if this is a production cluster under support/maintenance I don’t think you should mess around with CPU upgrades yourself as @bcaballero says!
Hi
I’ve taken a quick look for example to Node Replacement guide for 1065-G7. You can check it on this link: Checking That a Node Has Failed
Nutanix does not support replacing failed CPUs and not 100% sure, but, “upgrading” CPU I think it’s also not supported and you’ll need to expand your cluster with a new node to add more resources.
If I were you I would contact Nutanix Support to clarify this.
Would you clarify which is the scenario “upgrade Physical Processor in existing Node or adding a Node with higher CPU” ?
