Mastering Maintenance Mode Operations in Nutanix: A Guide for AHV and ESXi
As with years past, as we come to a close on year’s end, I take some time to clean up the As-Built documentation templates I maintain for deployments; as part of this activity, I always come across outdated sections based on current feature sets, or areas that I think can use some additional content.
This week, I noticed that my documentation about placing hosts into maintenance mode with Nutanix, whether running AHV or ESXi, is a bit outdated and could use some touching up.
Coming out of that, I thought it might be nice to discuss your different maintenance mode operations available with Nutanix and be a little hypervisor-specific for the options available.
I’ll write a 3-part series discussing the different scenarios for maintenance mode and detail the process and some known issues and/or limitations across the different hypervisors.
Today’s post will focus on maintenance mode and why it’s important. It will also cover maintenance mode operations with the Nutanix native hypervisor, AHV (Acropolis Hypervisor).
- Part 2 will cover ESXi.
- Part 3 will cover upgrading ESXi thru Prism.
The series will focus on AOS 6.5+, which is, at the time of this writing (12/23/23), the latest LTS release from Nutanix.
For this blog series, I’ll use a 4-node NX-1065 cluster imaged with the specific hypervisor for that post. For the ESXi post, I will use a pre-existing vCenter instance for cluster management.
