Converting from Raid 0 to Raid 1

Question

I am managing a Dell PowerEdge 2650 and have it accidentally set to Raid 0. Is there any way to convert that to Raid 1 safely. I was reading how the Dell Server Assistant CD could possibly do this, has anyone done this and if so how?

This is achieved from Array Manager if you have it installed. Right click the Virtual disk and click Configure or Add Member depending on your PERC. Add the available free disk and then change the Raid Type.

Problem is I am using Redhat ES 3, I think the Array Manager is Windows and Novel only, or is there a version that runs off the cd.

If you are running currently a 2-disk raid 0, you cannot change it to raid 1, because the container has the size of 2 disks, and cannot 'shrink' to just 1 disk.

If you are running a single disk raid 0 (more or less just a single disk), you may be able to convert it to raid 1.

As for how to do this, you'd have to go into the PERC bios. I'd very highly recommend you make sure you have a (tested) backup of your data before you do this, as the wrong choice in the change could mean you lose everything on the container.

If this is a LSI based array controller then you can use the 'Reconstruct' option in the Ctrl-M BIOS to perform this function.
