Unable to switchback during ANDU
Applies to
- 2 Node MetroCluster
- ONTAP 9
- ANDU
Issue
- When upgrading a 2 Node MetroCluster, you are unable to switchback after upgrading the first node.
- This can also occur without an upgrade taking place during a switchover / switchback operation.
Example:
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.
