升级到911或更高版本后、EMS日志上显示DNS警报
适用场景
- ONTAP 9
- CIFS/SMB
- 域名服务(DNS)
问题描述
- 在ONTAP从9.9.1升级到9.11.1版后、EMS日志会报告如下警报：
dns.server.timed.out: DNS server 192.168.100.31 did not respond to vserver = Vserver1 within timeout interval.- 运行vserver services name-service dns check命令时、DNS服务器会显示"off"、并显示错误"no route to host"或"Operation timed out "。
Cluster1::> dns check -vserver Vserver1
Name Server
Vserver Name Server Status Status Details
------------- --------------- ------------ --------------------------
Vserver1 192.168.100.31 down Operation timed out.
Vserver1 192.168.100.32 down No route to host.
2 entries were displayed.
- 在升级过程中、受影响的生命周期使用的服务策略发生了更改：
- 升级之前：
