The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Restoring RAID-5 configuration after RAID controller failure

Asked by Slavyan in Computer Servers, Disaster Recovery, Computer Hard Drives

Tags: RAID restore

Hello,
We have HP ProLiant DL100 G2 with RAID-5 consisting of 2 logical volumes/arrays. The other day the RAID controller failed with a BSOD Fatal Hardware Malfunction (see screenshots attached). After a phys check on the controller and re-inserting it, rebooting the box shows No Boot Media present, but at least we can log into the controller configuration though it does NOT show any members now, arrays - none. If we go into Disk Utlities menu in the same controller menu, we can see all disks fine. So the controller lost the configuration for both arrays and now need to re-initialize the disks and re-create the arrays meaning it will wipe all data from the old members, which we DO NOT really want. We are expecting a new controller very shortly.
Now the question: how do we restore the old members to the new controller w/o losing the data? We dont care for the system volume (we have an image), but it's the data volume which is important (~500GB of data and no backup (I know what you think now, but the server has a secondary role and RAID-5 was sufficient redundancy for it all this time)).
Appreciate your help.
S.
