This what it says: EMS Identifier callhome.client.app.err Severity ERR
Description : This message occurs when a remote client accesses the node using Manage ONTAP and triggers an event using the ems-autosupport-log API call with "auto-support" field set to "true". If your system is configured to do so, it generates and transmits an AutoSupport (or 'call home') message to NetApp Service and Support and to the configured destinations. Successful delivery of an AutoSupport message significantly improves problem determination and resolution.
Corrective Action : Identify and resolve the issue on the "remote client" that is using the Manage ONTAP API to trigger this event. If you need assistance, contact technical support.
Remote client is : EXDRUEARTOP007 (SnapManager for Exchange) and API it's using to generate autosupport : api-ems-autosupport-log
My advise would be: 1) Log on to filer and check the failed attempts: Run the following to verify the failed autosupport on 14th. filer> autosupport history show
2) check logs; filer>rdfile /etc/messages
3) login to EXDRUEARTOP007 and check the application logs (This is the root cause as per the EMS Correction Action), do you see any communication errors that happended between this machine and the EXDRUEARTOP007 ?
HTTPS is recommended to provide security however. support.netapp.com ports 80 and 443 generally only have to be open from the interface that has node management port built in. (hint: it's the one when you run hostname in /etc/rc)
You should find a log on the mail server as the prior poster mentioned.
