Hi all,

I have a current server running with a single disk in, we had a disk failure recently and managed to restore from a backup. We're now going to configure RAID 1 (2 identical drives) to keep a mirror in the event this happens again. My questions is can you setup a mirrored array on a live system without destroying the data thats on the currently installed disk?

Thanks

If you get hot swap drive cages for your drives then you can put in and take out while the server is in operation. If you put a new drive in at the moment you will probably short out the whole server.

Thanks for the reply.

Unfortunately our server doesnt support hot swappable drives as its a desktop form factor (HP ProLiant ML110 G5). I was going to shut the server down over the weekend, install the new drive, and configure the hardware RAID to setup mirroring. Would that work without destroying the data?
