Vmware Esxi Datastore Recovery _top_ ✧ (GENUINE)

A user or script deletes a VM folder, its .vmdk (virtual disk), or the entire datastore from the vSphere client.

If the datastore is not a snapshot but has disappeared entirely (e.g., the partition table was accidentally deleted or corrupted), ESXi may see the device as "Empty."

Note: The datastore will likely mount with a name like snap-XXXXX-OldName . You can rename it back to the original name, but remember that the VMs registered on the original datastore will still have their configuration files pointing to the old path. You will likely need to re-register the VMs in inventory. vmware esxi datastore recovery

If the datastore disappeared because the LUN was re-presented with a different ID, or if it was snapshotted at the array level, ESXi treats it as a "new" disk to prevent data corruption. This results in the datastore being marked as a .

Sometimes the GUI fails to mount the volume, or you need to force a resignaturing. This is done via the ESXi Shell (SSH). A user or script deletes a VM folder, its

Never attempt to format or recreate a VMFS datastore that contains unrecovered data. Always work on a copy or a storage snapshot first.

| Practice | Why It Helps | |----------|----------------| | (3-2-1 rule) | Fast recovery from any failure | | Storage snapshots (every 4–6 hrs) | Quick rollback of corruption | | Avoid over-provisioning | Prevents out-of-space corruption | | Use VMFS6 (vs VMFS5) | Better metadata protection & auto-UNMAP | | Monitor with vCenter alarms | Detect path failures early | | Test restores regularly | Validates backup integrity |

Once the partition table is fixed, refresh the storage adapter in vCenter. The VMFS volume should "pop" back up, and the datastore should mount automatically.
