适用场景

  • 适用于VMware vSphere的ONTAP 工具(OTV) 9.11及更早版本
  • VASA Provider

问题描述

如果打开或关闭了大量虚拟机、则会触发对VASA Provider (VP)的两种API调用:

  • UnbindVirtualVolume 
  • bindVirtualVolume 

使用VASA Provider 9.11及更早版本时、这些绑定/取消绑定API线程中的大量可能会累积、并提高OTV设备的CPU利用率。

在监控VASA Provider"立即运行"页面(https://VASA <OTV> :9083/RightNow)时、您会看到100个正在传输的绑定/取消绑定调用:

在OTV系统Shell中、Running Top显示vpserver (VASA Provider服务)是导致CPU利用率高的因素:
