What is the name of the command line utility that checks for VMFS5 metadata corruption?

A.
vmkfstools –check

B.
voma

C.
vmfsanalyzer

D.
esxcli vmfs check

Explanation:

It is possible to check VMFS for metadata inconsistency with a tool called VOMA (Vmware Ondisk Metadata
Analyser). With VOMA you can check VMFS3 and VMFS5 datastores.
Please note, that the tool can only identify problems, as it runs in a read-only mode. So it does not help you to fix detected errors.
