Vmfs Recovery Tool 'link' Access

The ESXi server crashes, and the datastore becomes "inaccessible" or "unmounted".

A typical recovery scenario unfolds as follows: After a failed storage firmware upgrade, an ESXi host no longer mounts a 4TB VMFS datastore, reporting "Device or resource busy" and "Metadata corruption." The administrator first powers off affected VMs to prevent further writes. The troubled LUN is then presented to a separate recovery workstation running a VMFS recovery tool. The tool performs a full scan of the LUN, bypassing the corrupt header, and identifies multiple recoverable partitions based on legacy superblock copies. Within hours, the tool displays a complete directory structure, including the "Virtual Machines" folder. The administrator selects the critical VMs, chooses a healthy NFS destination, and initiates the copy. After copying, the VMs are re-registered on a new vSphere cluster and powered on, typically with no data loss. This process, which would be impossible with standard OS utilities, is routine for a capable VMFS recovery tool.

Here are some proper features of a VMFS recovery tool:
