Symptoms

“Data Domain 容量利用率”报告中缺少所有针对 Data Domain 系统的基于 SNMP 的数据收集请求均失败,并显示以下错误消息:

Either host is down or invalid credentials have been provided

所有基于 SSH 的数据收集请求均已成功完成。  在调试低dpaagent.log中,SNMP 在尝试收集信息时请求超时,然后返回上述错误消息:

Data Domain 系统配置了多个 NIC 和 IP。  从 DPA 代理程序针对 Data Domain 短名称运行 nslookup 时,它会解析为多个 IP 地址,其中只有一个 IP (a.b.c.130) 是管理接口:

nslookup <DD_short_name>
Server:  <DNS_server_hostname>
Address:  <DNS_server_IP_address>

Name:    <DD_FQDN>
Addresses:  a.b.c.135
          a.b.c.133
          a.b.c.130
          a.b.c.132
          a.b.c.131
          a.b.c.136
          a.b.c.138
          a.b.c.134
          a.b.c.137

从 DPA 代理针对 Data Domain 主机名(如下所示)运行 snmpwalk 失败。

snmpwalk.exe -r:<DD_hostaname> -c:public -v:2c -p:161

针对管理接口的 IP 地址 (a.b.c.130) 运行 snmpwalk 成功完成,并从 Data Domain 返回数据。

 

Cause

Data Domain 系统配置为使用多个接口,但只有管理接口接受传入的 SNMP 请求。

 

Resolution

可以采取以下步骤来解决此问题:

  1. 登录到 DPA 代理程序系统
  2. 浏览至 hosts 文件(位置取决于作系统)
  3. 使用文本编辑器打开主机文件
  4. 添加或更新 Data Domain 主机名的条目,以便现在列出管理接口 IP
  5. 重新启动 DPA 代理程序服务
