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.
All results of a scan might be listed as Unknown.
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.
Schedule a scan or manually start a scan.
