问题描述

在某些采用SnapMirror活动同步(SMA)功能的ONTAP系统中、在对不同SMA关系执行计划内故障转移操作后、某些SMA源卷可能会发生I/O中断。
                         
     
如果cg2_vol_2上执行SnapMirror故障转移命令时
cg1_vol_dst cg2_src--cg2_vol_dst
cg2_src-- cg2_src\- cg2_vol_src-- cg2_vol\- cg2_vol_src--cg2_vol_dst可能会发生中断、如果cg2_vol_vol2
上的某个节点可能会发生中断、则此问题也可能会显示为20秒范围内的突发高延迟

受影响的卷

  • 此缺陷特定于SMAS卷、通常仅限于与正在进行计划内故障转移的CG的源端点位于同一位置的特定卷。
  • 非SMAS卷(例如、SM-S或SM-Async关系中的卷)不受影响。

症状
  • 用户可能会注意到读取或写入数据的延迟较长、通常延迟稳定一致、大约为20秒。
