Symptoms

當 SRDF 裝置設為異位模式時，R2 裝置會處於一致狀態，因此 symclone 建立會失敗，如下所示： 
  
symrdf -g test_dg que 
  
Device Group (DG) Name       : test_dg
DG's Type                    : ANY
DG's Symmetrix ID            : 000xxxxxxxxx    (Microcode Version: 5876)
Remote Symmetrix ID          : 000yyyyyyyyy    (Microcode Version: 5876)

The request is not allowed for SRDF/A-capable devices in async mode

Cause

當處於非同步模式的 R2 裝置被當作複製來源使用時，symclone 建立命令會失敗
，因為「建立」會執行彼此相隔的「重新建立/啟動」時刻。前置檔永遠也不可能有生效的機會。

但是-precopy 或 -copy 可用來維持 SRDF/A 一致性會話，同時建立複製複本。

Resolution

若要建立一致的複製副本，請分別執行「重新建立/啟動」命令，而非單一建立命令，這兩個動作都以串聯方式組成。

範例如下： 
  
symclone -g "test_dg" recreate -precopy -tgt
symclone -g "test_dg" activate -tgt -consistent

這樣可以有效地取代 symclone 建立。
