ONTAP从9.12.1P3还原到9.11.1P12

问题描述

从9.12.1P3降级到9.11.1P12已在步骤"system node rever-to -node <node_name>-version 9.11"中停止-

cluster::*> system node revert-to -node <node_name> -version 9.11 -check-only true
 Warning: This command reverts cluster configuration ONLY. The File system on
 every controller in the cluster must be reverted by running
 "revert_to" from the nodeshell on every controller. Example: run local
 revert_to 9.11
 Do you want to continue? {y|n}: y
 ...                 
 The management application is restarting as part of the revert process. Log in again to complete the revert task.
