Why each option
The voma utility (vSphere On-disk Metadata Analyzer) is the dedicated command-line tool for detecting and reporting VMFS metadata corruption on ESXi hosts.
vmkfstools is used for virtual disk and VMFS partition management tasks such as cloning, extending, and converting vmdk files; it does not have a '--check' flag for metadata corruption analysis.
voma is the official VMware ESXi utility designed specifically to analyze and report on-disk metadata inconsistencies for VMFS volumes; it is invoked as 'voma -m vmfs -f check -d <device>' and is the only tool that performs authoritative VMFS metadata integrity checks.
vmfsanalyzer is not a recognized VMware command-line utility; no such tool exists in the standard ESXi toolset.
'esxcli vmfs check' is not a valid esxcli namespace or command; esxcli does not expose a subcommand for VMFS metadata integrity checking.
Concept tested: VMFS metadata corruption checking with voma
