The volume TooksVolume state is DEGRADED: One or more devices could not be opened. Sufficient replicas exist for the pool to continue functioning in a degraded state.

What are the steps to add a new disk that is already in the server?

The manual covers this in great detail @okynnor - https://ixsystems.com/documentation/freenas/11.2/storage.html#replacing-a-failed-disk
You can always get to this by clicking the "guide" button at the very bottom left of the FreeNAS UI (new version).
