HP/HPE ProLiant Server Data Recovery

Direct answer

HP/HPE ProLiant servers use Smart Array (SA) and iLO for management. They fail from Smart Array failed, degraded logical drive, BBWC/FBWC failure, bad firmware updates and drive wear. HD Doctor recovers 91% of HPE cases with corporate emergency SLA.

Critical: do NOT force logical drive online via SSA/iLO with multiple drives off, do NOT update Smart Array firmware with degraded array, do NOT swap controller for different model without ACU dump.

How HP/HPE ProLiant works

HP/HPE ProLiant uses Smart Array (P410, P420, P440, P441, P840, MR416i, MR416i-o, SR932i-p) managing hardware RAID. iLO (4, 5, 6) for out-of-band management with Active Health System (AHS). DL series (rack 1U-4U), ML (tower), BL (blade c-Class), Apollo (HPC), Synergy (composable).

Common HP/HPE ProLiant symptoms

  • Logical drive in "Failed" or "Interim Recovery" in SSA
  • iLO reports drive failure or predictive failure
  • Server boot stuck with Smart Array error
  • BBWC/FBWC capacitor failure (cache in write-through)
  • Active Health System (AHS) reports critical events
  • POST fails with RAID controller message
  • Server won't boot after firmware upgrade

What NOT to do with a failing HP/HPE ProLiant

  1. 1.
    Do not force logical drive online via SSA/iLO with multiple drives off. Can write incorrect parity.
  2. 2.
    Do not update Smart Array firmware with degraded array. Updates can rewrite RAID metadata.
  3. 3.
    Do not swap Smart Array for different model without ACU dump. Different SAs store metadata in different locations.
  4. 4.
    Do not run "Clear Configuration" in SA. Wipes all logical drive configuration.
  5. 5.
    Do not force boot with BBWC failure. Write-through cache can corrupt writes.
  6. 6.
    Do not replace drives without documenting slot. Smart Array references position via metadata.

HP/HPE ProLiant FAQ

Smart Array reported logical drive failed. Recoverable?

Yes, in 91% of cases. Failed in SA is usually multiple drives off or corrupted metadata.

iLO reports predictive failure. Any chance?

Yes, in 90% of cases. Predictive failure is early warning. Stop and send for cloning.

Smart Array burned. Can I install another?

Only with prior ACU dump. Without dump, we analyze drives in lab.

BBWC failure on critical server. What to do?

Immediate backup. Write-through cache can corrupt writes.

Do you serve corporate servers with SLA?

Yes. For critical servers, 24h emergency SLA.

How does the quote work?

Diagnosis is free. After technical assessment within 24h we send a detailed quote.
