System powers back on, but your logical/virtual drive is missing in the HP SmartArray BIOS or OS.


HP SmartArray controllers sometimes fail to recognize virtual arrays after abrupt shutdowns, especially if cache wasn’t flushed.

This can be caused by:

  • Write-back cache corruption
  • Battery-backed cache failure
  • Partial drive dropout during boot

In many cases, the physical disks are fine — but the controller fails to reconstruct the map.


  • Don’t force-create a new logical drive — this wipes metadata.
  • Don’t assume all drives are healthy just because they’re detected.
  • Don’t “initialize” anything unless advised — that’s destructive.

✅ Check for missing cache module or expired cache battery alerts.
✅ Use JeannieLite to scan SmartArray metadata safely.
✅ Review drive order — HP controllers are very picky about this.


  • All physical drives show “OK” but logical volume won’t mount
  • Controller offers to create a new volume with existing disks
  • Bootable volume disappears from BIOS after rebuild attempt
