While the NotifierMngr resource can work without the NIC resource, Veritas recommends this dependency.

If the "en0" is a virtual device on AIX, then the NetworkHosts attribute is required, otherwise this resource takes an UNKNOWN state.

    SystemList = { sysA = 0, sysB = 1 }
    AutoStartList = { sysA, sysB }
    OnlineRetryLimit = 3
    OnlineRetryInterval = 120
    )

    NIC csgnic (
        Device = en0           
        NetworkHosts = {"fe80::88c4:e0ff:fe00:c002"}

        SmtpRecipients = { "user@domain.com" =
