HP DL380 RAID5 Mistake

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

  Eddy : Thanks for help, thought there might be a way to fix. Couple of quick questions. From instructions above, not sure what process is to: when saying insert drives as they were mean the failed one rather than the replacement and in same slots? "clear the controller setup" - does this just happen automatically on boot? "create a new raid5" - does this mean set up new logical drive and name same? how do you keep from reinitializing ? Answer no to accept data loss? How do you mark failed drive offline? Sorry, not familiar with the process, have not had drive in raid logical drive fail

  dyasny : the best thing you can do is call HP support and ask them to guide you through a re-tag procedure. That's what I have described above :)
