An administrator needs to upgrade AOS in a vSphere-based Nutanix five-node cluster with no automatic live migration. VMs have neither affinity nor anti-affinity rules configured. What will happen to VMs during the AOS upgrade?
A.
VMs will be rebooted on other hosts.
B.
VMs will continue to run on the same host.
C.
Upgrade fails because host can't go in maintenance mode.
D.
AOS automatically live migrate VMs to other hosts.
When upgrading AOS in a vSphere-based Nutanix cluster with no automatic live migration, the VMs will continue to run on the same host, providing that the VMs have neither affinity nor anti-affinity rules configured. The upgrade process will put the host into maintenance mode, which will cause the VMs running on that host to be suspended temporarily. Once the AOS upgrade is completed, the host will be taken out of maintenance mode, and the VMs will be resumed, but running on the same host. The AOS upgrade process does not automatically live migrate VMs to other hosts, because the automatic live migration feature is not enabled in the cluster.
VMs will be automatically migrated to other nodes during the AOS upgrade process.
Even though automatic live migration is not explicitly configured, Nutanix AOS will automatically initiate live migration of VMs to ensure that the upgrade process can proceed without disrupting services. Since there are no affinity or anti-affinity rules in place, AOS will choose the most suitable nodes for the migration based on factors such as load balancing and resource availability.
It's important to note that while the migration process is typically seamless, there's always a risk of minor disruptions or unexpected issues. Therefore, it's recommended to schedule the upgrade during off-peak hours or when critical services are not in use to minimize any potential impact.
User VMs may live migrate between hosts depending on what type of upgrade is performed but there should be no impact to their services. Users should maintain access to their VMs and be able to work as normal during the upgrade. VMs which cannot live migrate, such as those with vGPUs or Affinity Rules, will need to be powered-down or to have these settings removed in-advance of
any upgrade that requires a host reboot. Failure to do so will result in the upgrade becoming stuck in the process of evacuating User VMs.https://portal.nutanix.com/page/documents/details?targetId=Acropolis-Upgrade-Guide:upg-cluster-upgrade-aos-c.html
