适用场景

  • Active IQ健康风险
  • ONTAP
    • 9.11.1.
    • 9.10.1.
    • 9.9.1.
    • 9.8
  • AFF和FAS系统会受到影响
    • 数据聚合(不包括根聚合)
    • 其中、FAS系统是AFF系统卷的SnapMirror目标。如果FAS系统未用作AFF系统卷的SnapMirror目标、则该FAS系统不会公开给此问题描述。
    • 目标聚合已将自动自适应数据压缩节省设置为false
    • 涉及的SnapMirors和卷移动 

风险摘要

聚合已禁用自适应数据压缩,因此可能容易受到错误1493600的影响。

  • 在ONTAP 9.8到9.11.1版中、  如果 对某个卷执行以下一项或多项操作、     而该卷的目标聚合已将自动自适应数据压缩节省设置为false、但在以下任意写入操作期间以启用(true)状态运行、则数据可能会以不受支持的格式写入:
    • 卷移动操作。
    • SnapMirror数据保护(DP)传输。
    • 卷加密重新设置密钥 操作。
    • CSC (连续区块清理)扫描器操作。
    • 阻止重新分配扫描程序操作。
  • 对不受支持的块执行读取操作将触发控制器中断 、然后发生数据不一致、如下所示:
