Error message: GDDS233E GDDR MSC SDDF Reset for group msc-groupname 
delayed - (0919201821441111 - 45635.85 seconds ago)


在 SRDF/STAR 環境中，透過中斷 SRDF/S 關係中兩個站點之間的連結，測試組合行程。地理位置分散的災害重啟 （GDDR） 控制環境。  
鏈接被丟棄兩次。在第一次連結中斷和群組重走後，SDDF 工作階段成功復原。第二次刪除后，SDDF 會話將失敗，併發出GDDS233E消息。該消息指示 SDDF 會話的輪換已停止。

有關發生的事件順序，請參閱註釋部分。 

 


 

Cause

連結故障後，由於程式邏輯不正確，SDDF 工作階段處理在 SRDF/STAR 或 SRDF/SQAR 環境中停止。應同步更新的計數器中不匹配，但未更新，從而導致輪詢迴圈。 

Resolution

因應措施

  • 必須重新啟動 MSC 環境，才能啟用 SDDF 工作階段輪換。

永久修正

  • 針對 Mainframe Enablers 8.3，已開發程式暫時修正 （PTF） SF83083 和 PTF SR83049來修正此問題。這些程式可從 Dell EMC 線上支援下載。
  • 針對 Mainframe Enablers 8.2，已開發 PTF SF82142 和 PTF SR82088 來修正此問題。這些程式可從 Dell EMC 線上支援下載。
  • 針對 Mainframe Enablers 8.1，已開發 PTF SF81137 和 PTF SR81096 來修正此問題。這些程式可從 Dell EMC 線上支援下載。



 

Additional Information

在 Dell 實驗室環境中重新建立問題，並出現下列事件順序。

在工作階段 2 的重設 SDDF 過程中取消連結。SCF1543E和SCF1523E的訊息指出了問題。重設失敗，錯誤代碼為 87。錯誤代碼 87 在此情況下為正常現象，表示遠端命令失敗。

SDDF 輪換持續失敗，並出現遠端呼叫 syscall failure 87。

當連結重新連線時，會話 2 的第一個重置似乎完成，但只需要一個週期切換。在正常情況下需要四個週期才能完成。工作階段輪替似乎仍會照常進行。
