You might need to permanently remove a failed data center site from the StorageGRID system. To remove a site, you must decommission it.
Use this procedure to decommission a
StorageGRID site in which all nodes are disconnected from the grid (that is, use this procedure to remove a
disconnected site). In a disconnected site, every node in the site has a Connection State on the tab of one of the following:
- Unknown
: The node is not connected to the grid for an unknown reason. For example, the network connection between nodes has been lost or the power is down.
- Administratively Down
: The node is not connected to the grid for an expected reason. For example, the node, or services on the node, has been gracefully shut down.
Note: You cannot use this procedure if any node in the site is still connected to the grid (that is, if any node has a Connection State of
Connected

on the tab).
This procedure is designed to help you clean up after a disaster. For example, you can use this procedure to permanently remove a site destroyed by a fire or flood.
The flowchart shows the high-level steps for decommissioning a site in which all nodes are disconnected.
