Before performing any LCM (Life Cycle Manager) updates on a Nutanix cluster, it is essential to ensure that the AOS (Acropolis Operating System) is updated to the required or recommended version. AOS updates provide foundational enhancements, security patches, and compatibility improvements, which are critical for the successful execution of LCM updates.
From theNutanix Enterprise Cloud Administration (ECA)course materials:
“LCM updates depend on the underlying AOS version. Before proceeding with any hardware or software updates through LCM, administrators must ensure that the cluster is running a supported AOS version. This step ensures compatibility and prevents issues that can arise from dependencies between AOS and the update components.”
Additionally:
“AOS upgrades should be performed first to bring the cluster to a version that supports the desired LCM updates for components like BIOS, firmware, and hypervisors. This aligns the management stack with the latest features and security enhancements.”
Therefore, updating AOS before performing LCM updates is a mandatory prerequisite to ensure stability and supportability for the entire cluster lifecycle management process.
