HPE ProLiant servers are widely used in enterprise environments for high-performance computing and virtual. When a RAID 10 volume fails to mount, it can lead to significant business disruption, especially when hosting multiple virtual machines (VMs).
This case study details how we successfully recovered business-critical data and four virtualized systems from an HPE ProLiant RAID 10 server with 8 Seagate SCSI 1TB disks, after partition corruption rendered the RAID volume inaccessible.
As Ireland’s oldest and most experienced data recovery company, we used RAID reconstruction, partition table repair, and VM recovery techniques to restore the lost data.
The Challenge: RAID 10 Volume Not Mounting & Virtual Machines Inaccessible
A national engineering company contacted us after their HPE ProLiant RAID 10 server failed to mount, causing four virtual business systems to go offline. The reported issues included:
- RAID controller detecting the disks but failing to mount the RAID 10 volume.
- Partition table corruption preventing access to virtualized environments.
- Engineering project files, financial records, and operational data were at risk.
- Urgent need to recover four virtualized systems running separate business functions.
Since virtual – VHD systems store multiple business-critical applications, a rapid and professional recovery solution was required to minimise downtime.
Diagnosis & Evaluation
When the HPE ProLiant RAID 10 server arrived at our cleanroom facility, we conducted a full RAID and VM-level diagnostic. Our findings:
- Partition corruption – The primary partition table was damaged, preventing the operating system from recognising the RAID volume.
- RAID metadata inconsistencies – The RAID 10 configuration remained intact, but the volume was unreadable.
- No physical drive failure – All 8 Seagate SCSI disks were mechanically sound, meaning full data recovery was highly possible.
Since RAID 10 involves disk mirroring and striping, we were able to rebuild the partition structure while maintaining data integrity.
The Recovery Process
1. Cloning & Imaging All RAID 10 Drives
To prevent further corruption, we:
- Removed all 8 drives from the HPE ProLiant server.
- Created forensic sector-by-sector clones of each disk.
- Used write-blocking tools to ensure no additional modifications.
2. Manually Rebuilding the RAID 10 Array
Since the RAID metadata was intact but the partition table was corrupt, we:
- Reconstructed the RAID 10 array using advanced RAID recovery tools.
- Restored the missing partition table, making the file system readable again.
- Mounted the RAID 10 volume externally to extract stored data.
3. Recovering & Restoring Virtualized Systems
Since the RAID hosted four virtualized business systems, we:
- Extracted and repaired the VM disk files (VMDK, VHD, QCOW2).
- Rebuilt corrupted VM configurations to restore operational environments.
- Tested each virtual system to ensure full functionality before deployment.
The Results: 100% Data Recovery Success
Thanks to our RAID 10 partition repair and VM recovery techniques, we successfully recovered 100% of the engineering company’s critical business data, including:
✅ Four fully operational virtualized business environments
✅ Engineering project files, CAD drawings, and technical reports
✅ Financial records, operational documents, and compliance files
The company was able to restore operations without losing essential business data, preventing costly delays and downtime.
