FAS2240 queries wrong DNS Servers

Hello everyone,


I'm dealing with a pair of FAS2240s in HA configuration. I have a need to decommission a couple of DNS servers, so I updated the /etc/resolv.conf to point to new DNS servers, but they're still querying the original servers for remotesupportagent.netapp.com about once a minute. I want to be certain that they're querying the new designated DNS servers prior to removing the old ones, can anyone help me figure out why they refuse to query the new servers?


Both FAS2240's have had their /etc/resolv.conf updated, and I've tried toggling 'options dns.enable off/on'. Can't seem to get them to just start querying the new servers. Any help would be greatly appreciated. Thanks!

Seems like you have done everything to update the DNS entry on a 7-Mode system.




it might be holding on to the the connection which is already established. Should clear things up after a takeover-giveback (which is silly)




Try disconnectig the old DNS servers from network for a shot time.. to see the controller pickup the new DNS servers.


NetApp is not supporting RSA anymore... you should consider using Autosupport on Demand

by enabling ASUP via HTTPS as recommended by NetApp.

RSA should be the reason your controller's SP trying to reach https://remotesupportagent.netapp.com port 443

Thank you so much! A simple takeover/giveback fixed it immediately!

Yes, the Remote Support Diagnostics Tool and the Remote Support Agent component of it on the Service Processors is no longer functional.

See: End of Life: Remote Support Diagnostics Tool (RSDT) and Remote Support Enterprise (RSE)


You should definitely disable the RSA feature on all of your Service Processors to save bandwidth and SP CPU cycles.
