The command only works if all the specified slots are already associated with the node. +2. The command fails if the same slot is specified multiple times. +3. As a side effect of the command execution, the node may go into *down* state because not all hash slots are covered. + +## Usage in Redis Cluster + +This command only works in cluster mode and may be useful for +debugging and in order to manually orchestrate a cluster configuration +when a new cluster is created. It is currently not used by `redis-cli`, +and mainly exists for API completeness. + +@return + +@simple-string-reply: `OK` if the command was successful. Otherwise +an error is returned. |
