For check, fix, reshard, del-node, set-timeout you can specify the host and port of any working node in the cluster.

Cluster Manager Options:
  --cluster-yes      Automatic yes to cluster commands prompts
  --cluster-log      Display messages as log output
  --verbose          Verbose mode.
  -a <password>      Password to use when connecting to the server.
                     You can also use the REDISCLI_AUTH environment
                     variable to pass this password more safely
                     (if both are used, this argument takes precedence).
  --user <username>  Used to send ACL style 'AUTH username pass'. Needs -a.
  --pass <password>  Alias of -a for consistency with the new --user option.
