Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

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

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 –  Eddy Jun 8 '10 at 15:59
    
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 :) –  dyasny Jun 8 '10 at 17:12
