HP DL380 RAID5 Mistake

hphp-prolianthp-smart-arrayraid5

I had drives fail in both logical drives on a server. When I replaced failed 146GB drive in Raid 5 array with four (4) 146GB drives. On reboot the Smart Array controller asked if I wanted to accept data loss. Guess mistake to choose yes.

Can't seem to find a way to get system to repair RAID5 but it seems to want to just create a new partition.

Is there anyway I can go back and get the system to restore the data from other three drives now that I said accept data loss?

What you can do is as follows:

  1. remove all drives
  2. start server up, clear the controller setup
  3. power host down, insert drives as they were
  4. power host up, go into controller bios
  5. create a new raid5 exactly the way the old one was
    *make sure you do not reinitialise the new raid array!
  6. mark the failed drive as offline
  7. boot

This should take you into a booting degraded raid array. From here on you can replace the failed drive and assign the ew drive as hotspare, so it can rebuild the array
