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


通过删除 SRDF/S 关系中两个站点之间的链路，在 SRDF/STAR 环境中测试 ConGroup 跳闸。地理位置分散的灾难重启 （GDDR） 控制环境。  
链接被丢弃两次。在第一次链路断开和 ConGroup 跳闸后，SDDF 会话成功恢复。第二次丢弃后，SDDF 会话失败，并发出GDDS233E消息。该消息指示 SDDF 会话的轮换已停止。

有关发生的事件序列，请参阅备注部分。 

 


 

Cause

链路发生故障后，由于程序逻辑不正确，SRDF/STAR 或 SRDF/SQAR 环境中的 SDDF 会话处理会停止。应同步更新的计数器中的不匹配不会更新，从而导致轮询循环。 

Resolution

解决方法

  • 要启用 SDDF 会话轮换，需要重新启动 MSC 环境。

永久修复

  • 对于 Mainframe Enablers 8.3，已开发程序临时修复 （PTF） SF83083和 PTF SR83049来纠正此问题。它们可从 Dell EMC 在线支持网站下载。
  • 对于 Mainframe Enablers 8.2，已开发 PTF SF82142 和 PTF SR82088 来纠正此问题。它们可从 Dell EMC 在线支持网站下载。
  • 对于 Mainframe Enablers 8.1，已开发 PTF SF81137 和 PTF SR81096来纠正此问题。它们可从 Dell EMC 在线支持网站下载。



 

Additional Information

在戴尔实验室环境中重新创建问题，并看到以下一系列事件。

在会话 2 的 RESET SDDF 过程中断开链路。消息SCF1543E和SCF1523E指示问题。RESET 失败，错误代码为 87。在这种情况下，错误代码 87 是正常的，表示远程命令失败。
