Explanation

Before performing any maintenance on a Nutanix cluster - especially hardware changes - the administrator should first run NCC (Nutanix Cluster Check). NCC performs a comprehensive health check of the cluster (hardware, software, services, replication) to confirm the cluster is in a healthy state and safe to proceed. Performing maintenance on a cluster that already has a degraded component could result in data loss or an outage. Live migrating VMs (D) and stopping CVMs (A) are steps that come later in the process. Powering off a host (C) before confirming cluster health is risky on a 3-node cluster where RF2 tolerance is minimal.
