### Physical Disk Replacement
At this point, we need to physically go to the server and pull out the failing drive and replace it.
- Take note of the new serial number on the replacement drive and update the [Disk Arrays](https://docs.bunny-lab.io/Hardware/Storage%20Node%2001%20%28TrueNAS%20Core%29/Disk%20Arrays/) document accordingly.
- Insert the replacement drive back into the TrueNAS Core server
### Trigger Disk Re-Scan
Now we need to tell TrueNAS / FreeBSD to re-scan all disks to locate the new one.
- Within the TrueNAS Core WebUI, navigate to "**Shell**" and run the following command: `camcontrol rescan all`
- Navigate (back) to "**Storage > Pools > Status**"
- Locate the failed drive via it's `da` number again, and click the "**...**" elipsis menu button
