Common Hitachi Storage Failures We Recover
Even robust Hitachi arrays can fail due to hardware or configuration issues. We handle:
- RAID group degraded or offline in VSP or HNAS
- Controller or cache module failure
- Corrupted parity or incomplete rebuild
- Configuration loss after firmware update
- Power events causing metadata corruption
- Failed storage expansion or migration
- Missing or inaccessible LUNs
Our process includes safe disk imaging and accurate array reconstruction to restore original data structures.
Our Expertise in Hitachi Storage Recovery
We recover data from all Hitachi storage architectures, from legacy RAID systems to modern enterprise arrays.
Supported Systems
VSP G/F-Series, HNAS, AMS, USP, and modular arrays
RAID Levels
0, 1, 5, 6, 10, 50, 60
Environments
VMware, Windows Server, Linux, UNIX, AIX
Data Types
LUNs, volumes, snapshots, thin-provisioned storage
All recoveries use secure, non-destructive imaging methods to preserve integrity.
What to Avoid After a Hitachi Storage Failure
These steps prevent permanent damage and improve recovery success.
- Do not rebuild or reinitialize the array.
- Avoid drive removal or slot changes.
- Do not reset or downgrade firmware.
- Stop diagnostic or repair tools on failed volumes.
- Power down and contact professionals immediately.
