Sun Feb 19 01:04:29 GMT [FAS3210C-1: asup.post.retry:info]: AutoSupport message (HA Group Notification from FAS3210C-1 (PERFORMANCE DATA) INFO) was not posted to NetApp for host (0). The system will retry later to post the message
Nothing has changed that I'm aware of and I can traceroute to the IP. If I change it to SMTP it works OK.
Good catch on the firewall issue. I have heard of routing issues over undesired interfaces for issues including AutoSupport.
I don't know what release of Data ONTAP this is nor am I comfortable with my knowledge of IP routing inside of Data ONTAP.
I can comment that AutoSupport is blind to what interface it is assigned (it doesn't pick) and local IP address it uses. AutoSupport depends on the IP routing to do the right thing for the resultant IP address that is returned by the DNS/NIS/local host tables.
I ment from firewall. Sometimes people uses proxy servers when using http/https. I don't have too much experience about those..
But, mail addresses specified in autosupport.to and autosupport.partner.to fields receives autosupports always via smtp
you have three options in field: options autosupport.support.transport http | https | smtp If you pick http/https filer will send autosupports to netapp using options autosupport.support.url And with smtp filer will use options autosupport.support.to
I have to admit, that i haven't seen filers sending mails via http/https "Usually" filers do not have access to internet. Maybe if you have couple weeks old weekly_logs, where asup were sent to netapp via https? Then you can compare example ssl options and autosupport options if theres any changes happened.
