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:
DBG1 21920.22184 20200206:143435 agent.manager - agentManagerRunRequest(): Running request datadomain:status for target <DD_hostname> >> DBG2 21920.22184 20200206:143435 com.snmp - _aapiSNMPGetPDU(): attempting to get OID 1.3.6.1.4.1.19746.1.13.1.1.0 >> DBG2 21920.22184 20200206:165435 com.base.i18n - convertToUTF8Data(): convdata->conv is NULL DBG1 21920.22184 20200206:165435 com.snmp - _aapiSNMPGetPDU(): request timed out >> DBG2 21920.22184 20200206:165435 com.snmp - _aapiSNMPGetPDU(): attempting to get OID 1.3.6.1.2.1.1.1.0 >> DBG2 21920.22184 20200206:191435 com.base.i18n - convertToUTF8Data(): convdata->conv is NULL DBG1 21920.22184 20200206:191435 com.snmp - _aapiSNMPGetPDU(): request timed out DBG2 21920.22184 20200206:191435 com.base.i18n - convertToUTF8Data(): convdata->conv is NULL ERR 21920.22184 20200206:191435 agent.mod.dd - status_snmp(): Either host[<DD_hostname>] is down or invalid credentials has been provided >> DBG1 21920.22184 20200206:191435 agent.reporter - agentReportSend(): successfully sent report to server https://127.0.0.1:9002/dpa-api/agent/93616105-8123-4501-ab05-16c0cdfb595c/report DBG1 21920.22184 20200206:191435 agent.reqqueue - aapiReturnAgentRequest(): Request datadomain:status for target <DD_hostname>: will next run at 1581038975
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:
- 登入 DPA 代理程式系統
- 瀏覽至主機檔案 (位置取決於作業系統)
- 使用文字編輯器開啟主機檔案
- 新增或更新 Data Domain 主機名稱項目,管理介面 IP 現已列出
- 重新啟動 DPA 代理程式服務
