ANDU 期间无法切换回
适用于
- 2 节点 MetroCluster
- ONTAP 9
- ANDU
问题
- 升级 2 节点 MetroCluster 时，升级第一个节点后无法切回。
- 在切换/切回操作期间，即使不进行升级，也可能发生这种情况。
示例：
ClusterA::*>metrocluster switchback -simulate
Error: command failed: Failed to retrieve system image status information for all nodes. Reason: Failed to contact peer cluster "ClusterB" at addresses: 1.2.3.4, 1.2.3.5. RPC: Remote system error [from mgwd on node "ClusterA" (VSID: -1) to mgwd at 1.2.3.4, 1.2.3.5]. Verify that the nodes are healthy using the "cluster show" command and that cluster peering is available using the "cluster peer show" command, then retry the operation.
