Troubleshooting AutoSupport over SMTP

If the system does not send the AutoSupport message and you are using SMTP, you can check a number of settings to resolve the problem.

Before you begin

You determined that AutoSupport can generate the message, but not deliver the message over SMTP.

Steps

  1. At the clustershell CLI, ensure that DNS for the cluster is enabled and configured correctly by entering the following command:
    dns info
  2. At the clustershell CLI, check that the mail host specified in the configuration is a host that the storage system can talk to by entering the following command:
    ping mailhost

    mailhost is the name or IP address of your mail host.

  3. Log on to the host designated as the mail host and make sure that it can serve SMTP requests by entering the following command (25 is the listener SMTP port number):
    netstat -aAn|grep 25

    A message will appear, similar to the following text:

    ff64878c tcp        0      0  *.25    *.*    LISTEN.

  4. At the CLI for the storage system, ensure that the system is reaching the mail host successfully by entering the following command:
    traceroute -p mailhost

    mailhost is the name or IP address of your mail host.

  5. From some other host, telnet to the SMTP port by entering the following command:
    telnet mailhost 25

    A message similar to the following text is displayed:

    Trying 192.9.200.16 ...
    Connected to filer.
    Escape character is '^]'.
    220 filer.yourco.com Sendmail 4.1/SMI-4.1 ready at Thu, 30 Nov 95 10:49:04 PST

  6. Use the rdfile command to read the /etc/log/mlog/notifyd.log file.
