What is cold spare?
A 'cold spare' refers to all computer components, devices or devices that have to be configured and adjusted manually in the event of problems or total failure. It will require the suspension of normal computer / system operations until the component has been repaired and / or replaced.
A cold spare typically refers to storage devices.
A cold spare can be an internal or external computer component that is normally present in non-redundant systems with only one device instance.
If there is only one storage drive and is inoperable, the computer must be opened by a human operator to repair or replace the component, while redundant systems contain automatic failover spares.
A cold spare also refers to an external drive that is not connected to a system but is used in the event of a hot drive failure.
