CLUSTER MYID returns the receiving node’s ID: 40 hexadecimal characters that identify the node across the cluster. A node keeps its ID, which is saved in nodes.conf, until a CLUSTER RESET HARD gives it a new one. You pass this ID to commands such as CLUSTER REPLICATE, CLUSTER FORGET and CLUSTER SETSLOT.

The command also answers with cluster mode off.
