Updating a single Nutanix node
All the controller VMs of a Nutanix cluster have to have the same version of NOS installed. If you upgrade a cluster. All the CVMs are upgraded one-by-one.If you want to add a new node to the cluster, that node has to have to same version of NOS.
So what if you bought new Nutanix servers and they have a previous version of NOS installed. You cannot add this node to cluster because the NOS version is not the same.
There is a command that you can issue from a CVM that’s part of the cluster to upgrade a single Nutanix node.
- Login to a CVM that’s part of the cluster.
- Issue: /home/nutanix/cluster/bin/cluster -u [IP of the node that will be upgraded] upgrade_node
Note that this only upgrades the node and doesn’t downgrade it.
