All Updates in Compliance Reports Are Unknown

Scanning is the process in which you generate compliance information about vSphere objects against attached baselines and baseline groups. The compliance statuses of objects can be All Applicable, Non Compliant, Incompatible, Unknown, and Compliant.

Problem

All results of a scan might be listed as Unknown.

Cause

Such a condition typically indicates an error at the start of the scanning process. This might also indicate that no scan occurred or that the object is not supported for scan.

Solution

Schedule a scan or manually start a scan.
