NCP-MCI NCP-MCI-6.10 Release Date

Nutanix documentation explains that Reserved Capacity for a storage container allocates a guaranteed amount of physical space exclusively for that container. The internal description is:

“Reserved Capacity is space carved out from the storage pool for guaranteed use by a container. When a container’s reserved allocation approaches exhaustion, alerts are raised even if the overall cluster has ample free space.”

This means that although the physical cluster capacity may be sufficient, the container itself may hit its reserved limit, triggering an out-of-space forecast. Advertised Capacity determines an upper usage limit but does not produce this behavior. Replication Factor affects total usage but cannot explain container-only exhaustion when the cluster is fine. Compression levels influence data reduction but not capacity alerting mechanisms.

Thus, an oversized Reserved Capacity value is responsible for the alert.

When Life Cycle Manager (LCM) reports thata newer framework version is available, thecorrect actionis toperform an inventory scan (Option C).

Performing an inventory scan updates the available firmware/software versionsand allows LCM to download required updates.

Option A (Run an AOS upgrade)is unrelated to the LCM framework update process.

Option B (Run an AHV upgrade)is a separate component update and does not affect the LCM framework.

Option D (Download manually from a CVM)is not necessary because LCM updates are automatically pulled after an inventory scan.

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.
