ONTAP 9 ASUP SMTP Send fail / Switching to HTTP

kobusventer

Hi everyone.

I am sitting in a very awkward situation. I upgraded a storage system from ONTAP 9.7 to ONTAP 9.11, in steps. During the last upgrade from 9.10 to 9.11, ASUP "break" on the one node. The last automated ASUP sent was a waring on ONTAP 9.10 that the software is near its EOS date. Before the upgrade ASUP was working fine, AND ASUP is working fine on the second node.

Error:

Failed to transmit smtp asup 2711, curl error: Timeout was reached)

SO -

No problem on the SMTP server

No network coms error - I can log in via both nodes management ports (residing HOME on e0M)

Both nodes cannot ping the SMTP server. (I assume that they can ping the default gateway as I am able to log into the MGMT ports?)

Support suggested the normal thing - check SMTP server, etc etc. NO solution yet.

Fact is - this was working PRIOR to the upgrade.

Any ideas?

Then on HTTP/S

The Customer make use of firewalls and a proxy - I assume I should create a HTTP proxy for the management vfiler? The documentation is not very clear on this. I already applied for firwall access to the NA support IP, and is in the process to apply for wiferwall access to the PROXY server as well.

Is this the correct way of doing it?

Create HTTP proxy service on vserver (Customer use port 80)

Change ASUP transport to HTTP

Also check - if the port 25 blocked? Is Node able to reach out to DNS server ?

Hi, please see attached. The "related" issue is not applicable, as the systems was upgraded during December. Since that time, I am uploading the ASUPs weekly. Everything inside the SMTP troubleshooting guide was done. I removed any references to the system names from the log files. Please also note that the notify.log file was downloaded from spi.

Hi. This was NOT the solution. The issue "magically" disappeared after the system, was upgraded 9.12.1. Remember - I said that the issue occurred during the upgrade from 9.10 to 9.11. So - this thread can be marked as resolved by a system upgrade. Again - NO settings was changed during or after the initial upgrade, nor during the last to 9.12. Thanks for everyone's suggestions and support.

This is now resolved. The issue "magically" disappeared after the system, was upgraded 9.12.1.
