由于时间戳不匹配， ONTAP andu 升级 " 发生错误时暂停 "

适用场景

• ONTAP 9
• ANDU 升级已暂停

问题描述

• 集群更新挂起并显示状态 paused-on-error
• cluster image show-update-progress 状态为 paused" on error ，如下所示：

netapp::> cluster image show-update-progress

                                             Estimated         Elapsed
Update Phase         Status                 Duration     Duration
-------------------- ----------------- --------------- ---------------
Pre-update checks    completed              00:10:00      00:00:28
Data ONTAP updates   paused-on-error          01:32:00    3 days 22:40

•  查看 EMS 日志后，我们会看到升级期间时区发生了更改

• MGWD 日志进一步确认了由于时间戳不匹配而挂起的 ANDU
