mdm.ip.addresses缺少,且無法連線至叢集。

- MDM 上的 LIA 記錄指出執行失敗
scli --reset_management_trust,可能是由於mgmt_ca.pem憑證未新增至 MDM 信任存放區。

Cause
MDS Powerflex 系統中清查問題的根本原因,是在匯入程序之前未正確設定必要的憑證。可使用
mgmt_ca.pem 特別是必須在 MDM 信任存放區內正確建立憑證,以確保在匯入期間能成功擷取 MDM IP 位址。無法識別此憑證會導致連線問題和後續的清查問題。Resolution
1- 檢查 MDM 組態檔案:
去。
/opt/emc/scaleio/mdm/cfg
並列出憑證以確保憑證已產生
驗證 mgmt_ca.pem 憑證是否存在和最後幾個字元。2- 更新 CLI 信任存放區:
cat /root/.scli/cli_truststore.pem
如果在 CLI 信任存放區中找不到 mgmt_ca.pem 憑證,請新增該憑證。
scli --add_certificate --certificate_file /opt/emc/scaleio/mdm/cfg/mgmt_ca.pem.
3- 將憑證分散至 MDM:
確保mgmt_ca。所有 MDM 上皆有 pem 憑證,但仲裁者除外。
4- 移除並重新新增 MDS 閘道:
在資源頁面中,暫時移除 MDS 閘道以進行故障診斷。
5- 備份憑證:
使用 cp 命令建立 mgmt_ca.pem 和 mdm_mno_certificate.pem 的備份。
cp mgmt_ca.pem mgmt_ca.pem.bk cp mdm_mno_certificate.pem mdm_mno_certificate.pem.bk
6- 重新探索 MDS:
完成所有步驟後,請重新探索 MDS 以重新建立適當的系統功能。
