Backup Sangfor platform failed [#5223]Sangfor KVM: Error getting virtual machine.

Question

On a Sangfor SCP (HCI) 6.11.2 platform, virtual machine backup tasks fail with the error:

Obtaining VM configuration info error, [#5223] Sangfor KVM: Error getting virtual machine.

Answer

The error code [#5223] indicates that Vinchin is unable to retrieve the necessary configuration metadata from the Sangfor SCP platform. This failure is typically triggered when the underlying HCI cluster status is in an "ERROR" state, preventing the SCP API from responding to Vinchin's requests. In this specific case, the communication breakdown was caused by a cluster-level infrastructure issue rather than a backup software defect.

Resolution

Option 1: Infrastructure Recovery & Synchronization 

• HCI Cluster Health Check: Verify the health status of the Sangfor HCI cluster. If the cluster is in an "ERROR" state, resolve the hardware or service issues within the Sangfor management console first.

• Refresh Inventory: Once the HCI cluster returns to a "Normal" state, go to the Vinchin backup server web console and manually Sync Virtualization Platform to update the metadata cache.

• Verify Backup Services: Ensure that the agentless backup service is enabled within the Sangfor SCP settings.

Option 2: Alternative Data Retrieval (For UEFI VMs)

• SSH Configuration: If the VM uses UEFI boot mode and standard API calls fail, ensure that the VM allows SSH remote connections.

• Port Validation: Confirm that the required ports for data transmission between Vinchin and the Sangfor nodes are open (check firewall/security group rules).
