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

vmkfstools is used for virtual disk management tasks such as cloning and inflating VMDKs, but it does not have a '--check' flag for VMFS metadata validation.

VOMA (vSphere On-disk Metadata Analyzer) is the dedicated VMware tool for checking and repairing VMFS5 and VMFS6 on-disk metadata; it is invoked with 'voma -m vmfs -f check -d <device>' and is the only supported utility for this purpose.

vmfsanalyzer is not a real VMware utility and does not exist as a supported ESXi command-line tool.

esxcli provides a wide range of ESXi management subcommands, but 'esxcli vmfs check' is not a valid subcommand and cannot perform VMFS metadata integrity checks.
