Cause

信任鏈中有一個舊憑證。

Resolution

1.查看 DD 上的信任。 
  •     #adminaccess 信任顯示
  •     從預先檢查的錯誤中尋找對應的主機名稱。

範例：     
sysadmin@dd9300# adminaccess trust show
Subject                 Type         Valid From                 Valid Until                Fingerprint

2.向客戶確認他們是否仍在使用主機名稱發生錯誤的對應 DD 系統。系統已不再使用，這是常見的問題。它也可以用於 DDMC 監控。您也可以使用命令確認其是否用於複寫：
  •     #replication 顯示組態 
  •     這會檢查 DD 是否使用主機名稱進行 mtree 複寫，如果主機名稱在使用中，您必須重新產生憑證。 
  •      在此範例中，DD 已不再在使用中，且未在複寫組態中找到。
        
範例：  
sysadmin@dd9300# replication show  config
CTX   Source                                                  Destination                                             Connection                          Low-bw-optim   Crepl-gc-bw-optim   Encryption    Enabled   Max-repl-
                                                                                                                      Host and Port                                                          (Auth-mode)             streams
---   -----------------------------------------------------   -----------------------------------------------------   ---------------------------------   ------------   -----------------   -----------   -------   ---------
1     mtree://oaidsdd9300/data/col1/DD9300_2_RMAN   mtree://xlvdsdd9300/data/col1/DD9300_1_RMAN   xlvdsdd9300.xxxx.org   (default)   disabled       disabled            disabled      yes       32
---   -----------------------------------------------------   -----------------------------------------------------   ---------------------------------   ------------

3.如果確認複製或 DDMC 不需要信任，請移除舊的信任：
  •     # adminacces trust del host
  •     範例：# adminaccess trust del host cddsd8601
        
4.嘗試重新執行前置檢查，且應成功。
