+# Removing a Host from the Network
+
+Removing a host from the network is as simple as
+
+```
+isle host remove --hostname <name>
+```

+Keep in mind that if the host being removed had storage allocations set on it
+then the network will require some time to rebalance the stored data across the
+remaining storage hosts. This means that when removing multiple storage hosts
+from the network it is a good idea to wait a while in between each removal.
