Introduction

In ESXi 6.5, removing a virtual machine (VM) from inventory does not automatically delete its files from the datastore. However, administrators often face confusion regarding recovery, especially w the VM appears missing. Proper handling can restore most critical data, including configuration files, logs, and virtual disks. Jiwang Data Recovery specializes in guiding enterprises to safely recover removed VMs while preserving key data integrity.

Problem Definition

A VM removed from inventory in ESXi 6.5 can no longer be accessed through vCenter or the host interface. Users may mistakenly assume the VM is permanently deleted. The challenge lies in understanding what files remain on the datastore and how to reintegrate them without overwriting existing data. 技王数据恢复

Engineer Analysis

ESXi 6.5 stores VM files in VMFS datastores, including:

• Virtual disks (.vmdk)
• VM configuration files (.vmx)
• Logs (.log)
• Snapshot files (-delta.vmdk)

Removing a VM from inventory only unregisters it; the VM’s folder remains intact. Data recovery depends on whether the files were moved, deleted, or overwritten. Most critical data can be recovered by re-registering the VM or using professional VMFS-aware recovery tools if the files were partially deleted. www.sosit.com.cn

Common Causes of Inventory Removal Issues

• Accidental removal during maintenance or migration
• Miscommunication between vCenter and ESXi host
• Manual deletion of VM files in datastore
• Datastore corruption preventing VM registration

Recovery Procedure

1. Check the datastore for the VM folder and ensure VMDK, VMX, and log files exist.
2. Re-register the VM in ESXi by right-clicking the .vmx file and selecting "Add to Inventory".
3. If files are missing or partially deleted, use VMFS-aware recovery software to scan the datastore.
4. Recover deleted or corrupted files to a separate storage volume to prevent overwriting.
5. the recovered VM by registering it in a non-production environment to verify key data integrity.

Jiwang Data Recovery ensures that all critical configuration, disk, and log files are validated before reintegration, maximizing the chances of restoring key VM functionality.

Case Studies

Case Study 1: Windows VM Removed from Inventory on SSD Datastore

• Steps Taken:
  1. Verified VM folder presence on SSD datastore.
  2. Re-registered VM using the .vmx file.
  3. Used low-level VMFS scanner to recover partially deleted logs and snapshots.
  4. Validated recovered files in a test VM environment.
  5. Restored VM to production datastore.
• Expected Results: Most critical Windows VM data intact, including logs and configuration.
• Precautions: SSD writes were halted until recovery completed to prevent overwriting.

Case Study 2: Mac VM Removed from Inventory on NAS RAID

• Steps Taken:
  1. Verified RAID volume health and located VM folder on NAS.
  2. Re-registered the VM from .vmx files.
  3. Scanned for deleted VMDK and log files using professional recovery tools.
  4. Restored key snapshots and configuration files to isolated storage.
  5. Re-integrated VM into production environment after validation.
• Expected Results: Key Mac VM files restored, most critical data accessible.
• Precautions: RAID rebuild postponed; all recovery done on copied volume to preserve original files.

Cost & Success Rate

• SSD Datastore: $150–$300 per VM, 85–95% recovery of critical data.
• NAS or RAID: $300–$700, 70–90% recovery depending on volume health.
• External drives: $100–$250, up to 95% for intact VMDK and VMX files.

Recovery success largely depends on storage condition and whether files were overwritten. Jiwang Data Recovery provides accurate assessment before initiating procedures.

FAQ

1. Q: Can a VM removed from inventory be fully restored? A: Yes, if the underlying files remain intact. Most critical data can be recovered.
2. Q: What if some VM files are missing? A: Professional recovery software can often retrieve deleted VMDK, VMX, and log files.
3. Q: Can I safely power on the host during recovery? A: It is recommended to avoid writes to the datastore until recovery is complete.
4. Q: Does ESXi 6.5 keep snapshots w a VM is removed from inventory? A: Snapshots remain in the datastore and can be recovered if not deleted.
5. Q: How long does inventory recovery take? A: Recovery may take several hours to a few days, depending on datastore size and condition.
6. Q: Should RAID or NAS rebuilds wait until recovery is finished? A: Yes, rebuilds can overwrite recoverable data and reduce success rates.

Conclusion

ESXi 6.5 VMs removed from inventory can often be fully restored if the datastore files remain intact. Using proper re-registration methods and professional recovery tools ensures that most critical VM data—including VMDK, VMX, logs, and snapshots—can be recovered. Jiwang Data Recovery maximizes recovery success while minimizing risk to active systems, ensuring that key virtual machine data remains accessible and operational. 技王数据恢复
