适用场景

  • MetroCluster ( MCC )
  • ONTAP 主要版本>= 9.7
  • MCC上存在FlexCache 原始卷
  • 自动化无中断升级(ANDU)

问题描述

  • MCC运行从9.7及更高版本升级到9.8及更高版本的主要版本ONTAP。
  • MCC拥有FlexCache 关系的原始卷。
  • 为FlexCache 缓存卷提供服务的集群已运行高于MCC的ONTAP 主要版本。
  • 所有MCC节点组件均已升级、但 post-apps MCC上的一个集群组件升级任务中止、并出现错误:

MCC-A-01 1200 post-apps 1215 mgwd aborted    Upgrade and Revert task for FlexCache 9.8

  • MCC中受影响的集群仍会运行原始(升级前)有效集群版本、例如9.7、而其节点已运行新版本、例如9.8:

MCC-A::*> version
NetApp Release 9.7: Sat Jan 15 10:49:44 UTC 2022

MCC-A::*> node run -node * -command version
2 entries were acted on.
Node: MCC-A-01
NetApp Release 9.8
Node: MCC-A-02
NetApp Release 9.8

  • 升级状态指示post-apps 任务 失败Upgrade and Revert task for FlexCache
