RAID 1 HDD replacement with used HDD

We have an HD Proliant G8 with 2 HDDs built RAID 1. One of the HDD drive light becomes amber and iLO shows Bay 2 disk has a failure. I'd like to replace the failed drive with one pulled from other old servers that are idled. Those used HDD have the same size and model and also built RAID 1 as well. I've never done this before. Do I need to "wipe" the old HDD before hot-plugging it into this server? If so, how do I "wipe" the old disk using this G8 server? Plug that into say Bay 3, and have HP Intelligent Provisioning help on this (any detailed guide?)?

Solution 1:

P420i? No, you don't have to wipe the drive. Just hot-swap the failed/warning drive and rebuild should be starting.

If there are spare slots, you can also plug the replacement disk into one of those and start a manual replace in ACU - not much of a difference with RAID1 or a totally failed disk, but might speed up rebuilding with RAID5+ and a still generally functional drive.

While you're at it you might want to add a hot spare if you recycle an old drive.
