Node is not responding.

已尝试通过允许版本不匹配来执行接管、但失败如下错误：

cluster::*> storage failover takeover -ofnode Node-a800-02 -skip-lif-migration-before-takeover true -option allow-version-mismatch

Warning: Initiating a takeover while the partner is running a mismatched ONTAP

version is not recommended, unless you are performing a nondisruptive

upgrade or downgrade. Do you want to continue? {y|n}: y

Error: command failed: Failed to initiate takeover. Reason: partner versions of

WAFL and/or RAID are newer than this node.
