VMware vSphere – Cannot delete datastore with Error „An error occurred during host configuration. Operation failed, diagnostics report: Not a known device“<\/h3>\n

\"\"<\/a><\/p>\n

When attempting to remove an Inaccessible datastore in vSphere you get the following error :\u00a0„An error occurred during host configuration. Operation failed, diagnostics report: Not a known device“\u00a0<\/strong><\/p>\n

\"\"<\/a><\/p>\n

\n
\n
\n

The backing storage for the datastore has been removed rendering the datastore inaccessible in vCenter. \u00a0When the delete operation is run it can no longer find the disk to be removed this results in failure. \u00a0<\/p>\n<\/div>\n

The resolution is super easy, just run a „Rescan storage“ on all affected ESXi nodes and the inaccessible datastore is gone.\u00a0<\/p>\n<\/div>\n<\/div>\n
