We used to have SNMP to monitor all FC port down event. However, it causes a lot of un-necessary calls from NOC after hours. Because we have most of the prod servers setup with 4 HBAs, we decide to use SMTP alert to email to storage team members only. However, it never seems to work with DCNM. We did see Port up alert but not for Port down regardless of what settings we choose.
After opening a ticket with support, we were told the setting was disable by default. If you want to receive email alerts for port down event, go to Server Properties of DCNM. Look for event.linkDown.log and set it to True. By default, it is set to False. Then restart the DCNM services and port down alerts will be sent to your SMTP server depending on your setup.
