A VMFS5 datastore shows several errors, which suggests file system corruption.
Which tool could a vSphere administrator use to check the VMFS file system?
A. vSphere On-disk Metadata Analyzer (VOMA)
B. VMware Infrastructure Management Assistant (VIMA)
C. vSphere Storage APIs for Storage Awareness (VASA)
D. VMware vSphere Health Check Analyzer (VHCA)
Correct Answer: A
Explanation/Reference:
Explanation:
Use VMware Ondisk Metadata Analyser (VOMA) when you experience problems with your VMFS datastore and need to check metadata consistency of the VMFS or the logical volume backing the VMFS volume.
VOMA can check both the logical volume and the VMFS for metadata inconsistencies. You can use VOMA on VMFS3 and VMFS5 datastores. VOMA runs in a read-only mode and serves only to identify problems. VOMA does not fix errors that it detects.
Incorrect Answers:
B: VMware Infrastructure Management Assistant (VIMA) allows administrators and developers to run scripts or agents that interact with ESX and ESXi systems without having to explicitly authenticate each time. VIMA can also collect logging information from ESX and ESXi hosts and store the information on VIMA for analysis. It is not used to check a VMFS file system. Therefore, this answer is incorrect.
C: vSphere Storage APIs – Storage Awareness (VASA) is a set of APIs that permit arrays to integrate with vCenter for management functionality. Storage Vendor Providers allow vCenter Server to retrieve information from storage arrays including topology, capabilities and status. It is not used to check a VMFS file system. Therefore, this answer is incorrect.
D: VMware vSphere Health Check Analyzer (VHCA) automates the collection of VMware vSphere inventory, configuration, and utilization data, analyzes data against best practices, recommends grades, and generates a report card that presents observations, findings, and data categorized by VMware Health Check best practices. It is not used to check a VMFS file system. Therefore, this answer is incorrect.
