  • ONTAP をバージョン9.9.1から9.11.1にアップグレードすると、EMSログに次のようなアラートが報告されます。
dns.server.timed.out: DNS server 192.168.100.31 did not respond to vserver = Vserver1 within timeout interval.
  • vserver services name-service dns checkコマンドを実行すると、DNSサーバは「down」と表示され、「no route to host」または「Operation timed out」というエラーが表示されます。

Cluster1::> dns check -vserver Vserver1
