用ssh登陆进去后，老是有如下信息跳出
Thu Sep 15 08:08:26 GMT [DataOnTap2: asup.post.retry:info]: AutoSupport message (HA Group Notification from DataOnTap (REBOOT (reboot command)) INFO) was not posted to NetApp for host (0). The system will retry later to post the message
Thu Sep 15 08:12:27 GMT [DataOnTap2: asup.post.host:info]: AutoSupport (HA Group Notification from DataOnTap (REBOOT (reboot command)) INFO) cannot connect to url support.netapp.com (specified host not found)
Thu Sep 15 08:12:27 GMT [DataOnTap2: asup.post.drop:error]: AutoSupport message (HA Group Notification from DataOnTap (REBOOT (reboot command)) INFO) for host (0) was not posted to NetApp. The system will drop the message
1、“cannot connect to url support.netapp.com”应该是没有设置DNS，能ping通8.8.8.8，但是ping不通百度，肯定是dns解析的问题了。用web方式更改，打开“网络”--“dns和nis”，如下图
2、启用dns功能
3、这一步可以跳过
4、填写dns服务器和search list，我本地没有dns服务器，所以就用公网dns了。注意，“search list”一定要填写，否则dns设置不成功
5、这一步也可以跳过
6、设置完成后，用cli查看，可以看到设置成功

7、上面的信息就不会再次出现了
