/PASSWORD=password

    Specifies a password for cluster access. A password consists of
    1 to 31 characters, including alphanumeric characters, dollar
    signs, and underscores. A password provides a second level of
    validation to ensure the integrity of individual clusters on the
    same Ethernet that accidentally use identical group numbers. A
    password also prevents an intruder who discovers the group number
    from joining the cluster.
