convert raid 0 to raid 5

Is it possible to convert a raid 0 to raid 5? Here is some background information which promted this question. I have 2 identical servers, and they were both set up on raid 5. I shut them down and moved the drives from one server (keeping the drives in the correct order), and placed them into the second server. When I powered it up, the server booted to the os with no problem. I then noticed that only 3 of the 4 drives was being acessed, and when I checked the status of the array, it showed up as raid 0. I need to get this back on raid 5, with minimal down time. Can I morph it to raid 5 without reloading the os? I have the data backed up, but the app would take some time to get back up.

Hi,

Migrating between RAID levels is possible on some SmartArray controllers.

It would be useful to know exactly what servers you're using and what RAID controllers they have.

Given your description I would want to find out exactly why the RAID level changed though...

Hope this helps,

Regards,

Rob
