适用场景

  • ONTAP 9
  • 支持FabricPool或Cloud Tiering的系统

问题解答

  • 层扫描程序使用大多数可用的后台CPU周期。
  • 这些周期实际上与备用CPU周期相同、但用于确保数据有效分层。
  • 这是正常现象、不应用于考虑CPU利用率较高的情况。
  • 由于扫描程序数量和优先级的增加、ONTAP 9 11.1增加了CPU。
  • CONVA.12.1在wafl scan status 输出中引入了额外的重定向扫描程序、作为ONTAP 9 75534的修复。
  • CONVTA.14.1将分层扫描程序从10个增加到20个，如ONTAP 9 64247中所述，适用于所有系统，而不仅仅是AFF。
