HP Smart Array accessing a physical drive when the controller believes it's failing

  • 772

Is it possible to somehow access the raw block device hiding behind a HP SmartArray controller?

I have a JBOD disk connected through a SmartArray, and the second the controller thinks it's failing it makes it impossible to access the disk (which would be the desired behavior in a RAID array). I know from experience if I could get access to the raw block device I successfully recover 100% of the data stored on this disk, but the controller is not letting me get access to the disk.

How do you access a "failed" physicaldrive through a HP SmartArray?

  1. You can't access the RAW drive. It's going to have RAID metadata on it...

    If the controller believes the disk is failing, it's probably failing or failed. Smart Array controllers use S.M.A.R.T. as well as a number of other metrics to determine drive health. What are the LEDs on the drive indicating? Solid amber? Flashing amber?

    If you're in the unfortunate situation of having created multiple RAID 0 Logical Drives consisting of a single disk, you're out of luck.

    Can you provide more context about what happened and what you're trying to do?
