Hi,
Using this tool, you can identify the meaning of that error:
https://mysupport.netapp.com/eservice/ems
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 ?
Thanks!
