适用于

  • Cloud Volumes ONTAP (CVO) HA 双机热备组
  • Cloud Manager
  • AWS (Amazon Web Services)
  • EC2 (Elastic Compute Cloud) 控制台
  • EBS (Elastic Block Store)

问题

  • 使用 Cloud Manager 升级了 AWS CVO HA 对。
  • AWS EC2 控制台在升级完成后的短时间内将托管 AWS CVO 的 EC2 实例的 EBS 卷显示为离线。 

原因

  • 在升级过程中,CVO HA 对实例首先升级一个节点,然后升级另一个节点。
  • 节点升级后,它将重新启动,并导致附加到它的 EBS 卷暂时离线约 1.5 分钟。

解决方案

  • 这是 AWS HA 配置中 CVO 的正常行为。
  • 一旦节点和 EBS 卷恢复联机,此过程将再次对合作伙伴节点重复,其 EBS 卷也将短暂脱机(1.5 分钟)。
