Skip to main content

Nutanix Cluster Check (NCC) is a framework of scripts that can help diagnose cluster health. To help maintain cluster health and take advantage of the latest NCC technology, Nutanix recommends that you keep your NCC version current. You can upgrade NCC through the web console, Life Cycle Manager, or command line.

This version is not supported on clusters running AOS versions prior to 5.10 or any AOS Family for IBM CS Series platforms. NCC 3.10.1 and below is supported on clusters running AOS versions prior to 5.10. See Knowledge Base article 7796 on the Nutanix Support portal.
