OKM升级错误：无法验证映像签名

适用场景

问题描述

如果集群中的OKM处于CC模式、则在该集群上下载ONTAP 映像可能会遇到以下错误：

CLI 错误消息：

Failed to verify the signatures of the image. The image may
have been corrupted. Replace the image, and then try the command
again., Action: Use the "cluster show" command to verify that all
nodes in the cluster are healthy. Use the "cluster image package
show-repository" command to verify that the downloaded image has
the correct version. If all nodes are healthy and the image has the
correct version, wait a few minutes, and then use the "cluste
image resume-update" command to resume the update.

示例： 

system node image update -replace image2 -node netappnode0* -package http://Web_server/97P5_q_image.tgz -setdefault true

Warning: The recommended best-practice is to use the automated non-disruptive update procedure if you are attempting an    upgrade or a minor version downgrade. Refer to the Clustered Data ONTAP Upgrade and Revert/Downgrade Guide for details.
