Explanation

A Controller VM (CVM) failure is the component failure that reduces Data Resiliency Status to 0 for the affected components. Each AHV node's CVM handles all storage I/O for that node and participates in the cluster's distributed storage fabric. When a CVM goes down, the cluster loses a storage controller, and Nutanix's resiliency calculations reflect that it can no longer guarantee tolerating an additional node failure without data unavailability-dropping the resiliency factor to 0. A disk failure (B) typically reduces resiliency by one unit but does not immediately drop it to 0 in a healthy cluster. A node (C) or block (D) failure would also impact resiliency but the exhibit's pattern points to a CVM as the root cause.
