Avamar 和 Data Domain 整合：無法同步憑證與已啟用的會話安全性

摘要: 在 Avamar 上啟用會話安全性時，憑證必須在 Avamar 和 Data Domain 之間同步。這需要在 Data Domain 上啟用 SCP 通訊協定。

症狀

備份可能會失敗，並顯示下列錯誤： 
DDR result code: 5049, desc: file not found
DDR result code: 5341, desc: SSL library error "failed to import host or ca certificate automatically"
DDR result code: 5008, desc: invalid argument
在遵循 197106、Avamar 和 Data Domain Integration 197106 Dell 文章時：DD 在 Avamar AUI 和或使用者介面解析度路徑中顯示紅色時，不會產生憑證。

檢查 MCS 記錄時，有與 SCP 通訊協定相關的例外情形。

原因

檢閱 mcserver 記錄： 
/usr/local/avamar/var/mc/server_log/mcserver.log.0

Caused by: java.io.IOException: SCP unexpected cmd: Scp is disabled. Access denied.
這表示 Data Domain 上的 SCP 通訊協定已停用。

Avamar 和 Data Domain 之間的同步憑證流程需要啟用 SCP，如下所示：
  1. Avamar 使用 Data Domain 公開金鑰在 Data Domain 上執行命令，以進行無密碼驗證。第一個命令是在 Data Domain 上產生憑證簽章要求 （CSR）。
  2. Avamar 接著嘗試使用 SCP 從 Data Domain 複製 CSR，但在 Data Domain 上停用 SCP 時卻無法複製。
  3. Avamar 會使用 CSR 簽署 Avamar 根憑證發行給 Data Domain 的憑證。在 Data Domain 上，它稱為「imported-host ddboost」憑證。
檢查 Data Domain 使用者介面顯示 SCP 已停用：
