DNS检查失败、并显示"没有路由到主机"
::> dns check -vserver svm1 Name Server Vserver Name Server Status Status Details ------------- --------------- ------------ -------------------------- svm1 10.yy.xx.5 down No route to host. svm1 10.xx.xx.228 down No route to host. svm1 10.xx.xx.236 down No route to host. 3 entries were displayed.

LDAP检查显示状态为"down"、并显示详细信息"DNS解析失败"
::> ldap check -vserver svm1 Vserver: svm1 Client Configuration Name: qed-ldap LDAP Status: down LDAP Status Details: DNS resolution failed for all the hostnames specified with "-ldap-servers", Vserver: "svm1". LDAP DN Status Details: DNS resolution failed for all the hostnames specified with "-ldap-servers", Vserver: "svm1".
