HP P212 Mirrored Raid

Hey Experts
This is kind of a general question of does it work.
I have a 500GB single drive connected to a HP P212 raid card. Not raided or anything just a standalone drive.
If i add a second 500GB drive identical to the first can i mirror them without having to reload the OS or image it or anything? Just place the drive in and turn mirroring on?

Casey Herman

If the OS is Windows, you can mirror them through disk manager. If not, you will probably have to reload if you try to create a mirrored array in the adapter after the fact.

Mirror through disk manger? Isnt that the windows software mirror? A P212 is a hardware RAID controller...

Casey Herman

It matters not.... if you have two JBOD disk attached to a RAID controller, you can still use OS mirroring.

Why would i ever want to use software mirroring over hardware mirroring?

Casey Herman

Mainly if you arent using a hardware controller.. You should always use hardware where you can.
A software mirror can be done without a reload.

Before you follow qikkel's advice, which I am not saying is wrong... but it could be, make sure your data is backed up. HP array controllers can be contrary and you could end up reloading anyway.

Hope this helps

Found in the documentation that it requires the BBWC to be able to do this.

Thanks, but I think you should split points with glikel. It is a single drive in RAID 0 at the moment as far as the software is concerned as it has the right metadata on it.
