raid scrub for hp dynamic smart arrays

  • 772

I'm new to hp servers. we own an hp dl160 gen9 with soft raid. it uses the b140i controller to manage 4 LFF in raid 5.

My question is: how can I scrub the raid? I've installed the hpssacli utils: while they allow me to have a report on the controller and array status, I can not find any reference to data scrubbing.

In linux soft raid I was used to program a periodic check of raid data, I would like to reproduce the same on this server.

thank you.

    You don't need to do anything. The controller handles this in the background.

    This is also a feature of the fakeraid Dynamic Smart Areay controllers.

    Smart Array controllers perform a background surface analysis during inactive periods, continually scanning all drives for media defects. Smart Array controllers can also detect media defects when accessing a bad sector during busy periods. If a Smart Array controller finds a recoverable media defect, the controller automatically remaps the bad sector to a reserve area on the disk drive. If the controller finds an unrecoverable media defect and you have configured a fault-tolerant logical drive, the controller automatically regenerates the data and writes it to the remapped reserved area on the disk drive.
