Does anyone has ever seen this?
- I am able to resolve any name in the domain using ping command on ONTAP (9.7P3);
- dns check command fails with server down and Operation Timed Out:
It smells like a bug. I am almost opening a case with NetApp to check.
See The Solution
Could be. I’d patch to p6 anyway.
Try using “-instance” at the end of the command. Might have more details. Check your routes with “route show”
DNS check does a basic A record query for example.domain.com. Nothing fancy.
Perhaps your DNS server blocks queries like that?
54 2.087774 10.193.67.237 10.193.67.236 DNS 78 Standard query 0x96b2 A example.ntap.local
55 2.088023 10.193.67.236 10.193.67.237 DNS 142 Standard query response 0x96b2 No such name A example.ntap.local SOA oneway.ntap.local
::*> dns check -vserver DEMOName ServerVserver Name Server Status Status Details------------- --------------- ------------ --------------------------DEMO x.x.x.x up Response time (msec): 46
Also, you might check with a tcpdump command too.
I haven't seen many if any cases of where there were problems with DNS resolution or connectivity in general in 9.7.
Thanks everyone that tried to help. I was reviewing the "UPGRADE ADVISOR PLAN ADDENDUM" and saw on it the following:
" The "vserver services name-service dns check" command reports "Operation timed out" "
This information is bundled with a link to a BUG: https://mysupport.netapp.com/NOW/cgi-bin/bol?Type=Detail&Display=1151206
I think that it may be the issue I am facing. Since it is not being a problem now, it's ok.
