This is a command line workaround to test NotifierMngr will send an email when a resource faults. A dummy service group is created and also a dummy resource of type of FileNone. If the file does not exist the resource will fault and NotifierMngr should send an email from the server specified in SmtpServer.

Here is a basic example of a  NotifierMngr resource configuration with a brief explanation of the resource attributes used.

NotifierMngr ntfr (
               Critical = 0
               SmtpServer = localhost
               SmtpFromPath = "vcs_alert@your_company.com"
               SmtpRecipients = { "user_to_be_notified@your_company.com" = Warning }
               )

SmtpServer : Specifies the machine name of the SMTP server.

SmtpFromPath : Set to a valid email address, if you want the notifier to use a custom email address in the FROM: field. Type and dimension: string-scalar Example: "usera@example.com"

SmtpRecipients: Specifies the email address where SMTP sends information and the severity level of the messages. The severity levels of messages are Information, Warning, Error, and SevereError. Specifying a given severity level for messages indicates that all messages of equal or higher severity are received.


Create the dummy service group and resource:

# haconf -makerw
# hagrp -add dummySG
VCS NOTICE V-16-1-10136 Group added; populating SystemList and setting the Parallel attribute recommended before adding resources
# hagrp -modify dummySG SystemList 0 1
# hares -add dummyResource FileNone dummySG

# hares -modify dummyResource PathName /tmp/dummyfile
# haconf -dump

 

The service group would look like this in the main.cf file:

group dummySG (
       SystemList = { primary_servername = 0, secondary_servername = 1 }
       )
       FileNone dummyResource (
               Critical = 0
               PathName = "/tmp/dummyfile"
               )

Now enable the resource - it should fault immediately
# hares -modify dummyResource Enabled 1

The resource should fault and NotifierMngr should send an email to the SmtpRecipients immediately after the resource is enabled. A resource fault is considered a SevereError so the severity level of Warning specified in the NotifierMngr resource example would include this.

If the email has been sent and received then the test is complete - the dummyResource and dummySG can be deleted

# hares -delete dummyResource
# hagrp -delete dummySG
# haconf -dump -makero
