Symptoms

Data Domain 容量使用率報告中遺失 Data Domain 系統的所有 SNMP 型資料收集要求均失敗,並顯示下列錯誤訊息:

Either host is down or invalid credentials have been provided

所有基於 SSH 的數據收集請求都成功完成。  在偵錯低dpaagent.log中,SNMP 要求逾時以嘗試收集資訊,然後傳回上述錯誤訊息:

Data Domain 系統設定了多個 NIC 和 IP。  從 DPA 代理程式針對 Data Domain 短名稱執行 nslookup 時,它會解析成多個 IP 位址,其中只有一個 IP (a.b.c.130) 是管理介面:

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

從 DPA 代理程式針對 Data Domain 主機名稱 (如下所示) 執行 snmpwalk 失敗。

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

針對管理介面 (a.b.c.130) 的 IP 位址執行 snmpwalk 會成功完成,並從 Data Domain 傳回資料。

 

Cause

Data Domain 系統已設定為使用多個介面,但僅管理介面接受傳入的 SNMP 要求。

 

Resolution

可以採取下列步驟來解決問題:

  1. 登入 DPA 代理程式系統
  2. 瀏覽至主機檔案 (位置取決於作業系統)
  3. 使用文字編輯器開啟主機檔案
  4. 新增或更新 Data Domain 主機名稱項目,管理介面 IP 現已列出
  5. 重新啟動 DPA 代理程式服務
