问题描述

节点上的Vserver具有多个生命周期。
DNS检查失败。
CIFS访问在Vserver上受影响。

示例：

Cluster::> dns check -vserver vserver_name -name-server DNS_server IP

Vserver: versver_name

Name Server: DNS_server IP

Name Server Status: down

Status Details: Operation timed out

SECD.GZ显示：

secd: secd.conn.auth.failure:notice]: Vserver (vserver_name) could not make a connection over the network to server (ip DNS_server IP, port 389). Error: Operation timed out (Service: LDAP (Active Directory), Operation: SiteDiscovery).
