问题

在 ONTAP 升级期间，一个节点升级 ONTAP 版本，但无法启动以继续接管/交还

Cluster::*> cluster image show Node Current Version Installation Date -------------------- ----------------------- ------------------- Node-01 9.16.1P6 xx/xx/xxxx 21:24:12 Node-02 9.16.1P11 xx/xx/xxxx 16:43:20

检查存储故障转移显示我们可以看到互连问题：

Cluster::> sto fail show (storage failover show) Node Partner Possible State Description -------------- -------------- -------- ------------------------------------- Node-01 Node-02 false Waiting for Node-02, Takeover is not possible: Storage failover interconnect error, NVRAM log not synchronized, Disk inventory not exchanged Node-02 Node-01 false Waiting for Node-01, Takeover is not possible: Storage failover interconnect error, NVRAM log not synchronized, Disk inventory not exchanged

当我们检查互连状态时，我们看到链路已启动，但 RDMA 已关闭

Cluster::*> ha interconnect status show (system ha interconnect status show) Node: Node-01 Link 0 Status: up Link 1 Status: up Is Link 0 Active: true Is Link 1 Active: true IC RDMA Connection: down Node: Node-02 Link 0 Status: up Link 1 Status: up Is Link 0 Active: true Is Link 1 Active: true IC RDMA Connection: down
