适用场景

  • NetApp ONTAP 9.
  • Microsoft Windows® Server 2016

问题解答

  • 这是一个设置的注册表值，您只需在主机操作系统层设置一个选项即可有效地每 30 秒在所有路径上探测目标。  0表示禁用此功能、1表示启用此功能。 
  • Windows Unified Host Utilities 7.1将设置为0，并 在7.2版中设置为1 (请查看最新文档以了解此中的任何更改。)
    1. HKLM\SYSTEM\CurrentControlSet\Services\mpio\Parameters\PathVerifyEnabled

请在对这些参数进行任何更改之前咨询这些技术支持资源，因为所有供应商不支持的任何配置都可能导致数据访问丢失。

  1. 主机操作系统。
  2. 适用于启动程序的主机总线适配器（ HBA ）供应商和 MPIO 驱动程序文档。
  3. 存储平台最佳实践文档。
