When diagnosing and resolving a disk failure in a VMware vSAN cluster — especially with Deduplication and Compression enabled — the most appropriate and comprehensive tool is: vSAN Skyline Health This tool provides: -Real-time health checks specific to vSAN components (disks, network, cluster, etc.) -Awareness of advanced features like Deduplication and Compression -Guided diagnostics and automated recommendations -Visibility into disk group issues, such as component failures, object health, and unmounted disk groups Skyline Advisor (cloud service): EOL since October 4, 2024 — discontinued. Skyline Health (in‑product) and Skyline Health Diagnostics (on‑prem): still supported and recommended for troubleshooting — including diagnosing disk issues in vSAN.

Skyline only helps for monitoring and give recommendations but cannot solve the disk failure.
