适用场景

  • 双节点MetroCluster
  • ONTAP 9
  • 在ONTAP升级期间自动计划外切换(Automatic UnArun已 计划切换、AUSO)
  • 切回失败

问题描述

  1. 正在执行手动ONTAP升级。
  2. 切换失败、因此节点重新启动、从而触发ASUSO。
  3. 聚合修复 失败、并显示错误:

Error: command failed: Unable to perform the MetroCluster operation because of a Data ONTAP version mismatch. All nodes in a MetroCluster configuration must have the same version for both the current and default images.

4. 已按照 由于Data ONTAP版本不匹配而无法升级双节点MetroCluster 中的步骤进行操作、但命令失败并显示错误:

Error: command failed: Cannot change default software image. One or more aggregates are not online. Use the "storage aggregate show -state !online" command to list them.

Cluster_B::*> stor aggr show -state !online
