Storage state comes first
Recovery decisions are stronger when the original media, virtual disks, snapshots and backup targets are preserved before repair attempts.
VMware recovery - Vancouver lab
Business storage quick-start
Preserve the storage state before repairs, imports, rebuilds or restores change the evidence.
- Stop write-heavy repairs and restore-over-original attempts
- Record the storage layout and recent event timeline
- Keep original media, VM files and backup media together
VMware datastore or virtual machine down? Preserve the storage state first.
VMware recovery can involve several layers at once: the physical RAID or NAS, VMFS datastore metadata, VMDK virtual disks, snapshots, guest file systems and the application data inside the virtual machine. Aceon helps assess ESXi, VMFS, VMDK and VMware-backed business storage failures before rebuilds, resignature attempts or repair utilities make the case harder.
- ESXi host and VMFS datastore failures
- VMDK, snapshot-chain and guest file-system problems
- RAID, NAS and iSCSI-backed VMware storage
- Business VMs, databases, file servers and backup repositories
Business context matters
Databases, VMs and shared folders often support staff, customers, accounting, dispatch or production work.
Route the case quickly
A short triage call can prevent rebuilds, imports, scans or restores from reducing options.
VMware failures are not just one-file problems.
VMware failures are not just one-file problems.
A failed VM may involve physical storage, hypervisor metadata, virtual disks, snapshots and the guest operating system. The safest first step is to understand the storage layout and the recent event timeline before writing anything back to the affected datastore.
- VMFS datastore, ESXi host and RAID/NAS storage triage
- VMDK descriptor, flat-file, sparse disk and snapshot-chain review
- Guest file systems, databases and business shares inside recovered VMs
- Backup repository and clone handling when originals are damaged
What to gather before calling.
What to gather before calling.
Partial notes are enough. The important part is to stop new writes and keep the original storage evidence intact.
- ESXi version and host/storage model if known
- Datastore name, RAID/NAS/iSCSI layout and drive count
- Recent failures: power loss, disk replacement, rebuild, update, repair tool, backup restore
- Whether the VM, datastore, or underlying storage is still partially visible

Need outage guidance first?
Ask Aceon to call you back about the server case.
Use this short callback form when you want human triage but cannot talk right now.

Send the server, VM or database case details now.
Use this form when the system is stable enough to wait briefly for reviewed follow-up. For active outages, degraded arrays, or cases where every minute matters, calling is still the safer move.
FAQ
Common questions
Can Aceon help with VMFS and VMDK recovery?
Yes. Aceon can assess VMware, ESXi, VMFS, VMDK, snapshot and guest file-system cases where the storage state allows recovery work.
Should I try to mount or resignature the datastore?
Not until the storage state is understood. Mount, resignature, consolidation and repair attempts can change metadata and reduce recovery options.
What if the VMware host uses QNAP, Synology or iSCSI storage?
Treat the NAS, RAID or iSCSI layer as part of the case. Preserve drive order and avoid rebuilds while the full layout is reviewed.
