Bringing down a cluster is a scary thing, isn’t it? What if it does not come back? What if this is not the right sequence? What if you make a typo? What if...
Unfortunately, no matter how much one frets the task there is always a point when a cluster must be powered off. We thought we would hold your hand along the way at least figuratively speaking and provide you with a guide on the process so that the next time you consider that pesky network maintenance or emulation of DR or prepare for a site power outage or a re-location you would be all prepared for the task.
In this post we will cover the process for the vSphere based clusters:
Upgrade to the most recent version of NCC before proceeding with the following steps.
- For Metro Availability (Data Protection) Disable Metro Availability and Verify no Async DR replications are in progress.
- Shutting down guest VMs (Do not shut down the Nutanix Controller VMs.)
- Shutting down vCenter VM (if applicable).
- Shutting down Nutanix Files (file server) VMs.
- Stopping the Nutanix cluster.
- Shutting down each node in the cluster.
- Power on the nodes and cluster after a shutdown.
- Start the cluster.
For detailed instructions and commands please refer to KB-1438 Shutting down Nutanix cluster running VMware vSphere for maintenance or relocation.
