The following table provides troubleshooting guidance on protection issues for Hyper-V virtual machines.
| Issue | Reason | Workaround |
|---|---|---|
DPM error: DPM failed to synchronize changes for Microsoft Hyper-V \Backup Using Child Partition Snapshot\<<VM Name>> on <<Resource Group>> because the snapshot volume did not have sufficient storage space to hold the churn on the protected computer (ID 30115 Details: Unknown error (0x8004231f) (0x8004231F)) |
Insufficient storage in snapshot pool. |
Verify that the SAN has enough available storage to create hardware snapshots. |
DPM error: The VSS application writer or the VSS provider is in a bad state. Either it was already in a bad state or it entered a bad state during the current operation. (ID 30111 Details: Unknown error (0x800423f4) (0x800423F4)) VMMS event: No snapshots to revert were found for virtual machine 'CSVVM02'. (Virtual machine ID 4774EF60-F4B6-47D6-A0B9-60452C6B7FE8) |
Auto-mounting of volumes might not be enabled on the protected computer. |
Enable auto-mounting by using the following command: |
DPM error: The VSS application writer or the VSS provider is in a bad state. Either it was already in a bad state or it entered a bad state during the current operation. (ID 30111 Details: Unknown error (0x80042306) (0x80042306)) |
The hardware provider has vetoed snapshot creation. |
This is potentially a configuration issue. Check the application event logs for VSS hardware provider events and validate the storage configuration with your SAN vendor. |
The operation failed for Microsoft Hyper-V \Backup Using Child Partition Snapshot\Win7.01 on Win7.01.dpmcsv1.DC505.LAB because the data source is not available. (ID 30169 Details: Unknown error (0x80042308) (0x80042308)) |
Live migration caused the virtual machine to move to another node while the backup was in progress. Cluster disks are in a bad state. Data source was deleted. |
|
DPM error: Failed to prepare a Cluster Shared Volume (CSV) for backup as another backup using the same CSV is in progress. (ID 32612 Details: Unknown error (0x8007173d) (0x8007173D)) |
Too many parallel backups are competing for the same CSV LUN. |
For information about how to enforce serial backups, in the DPM 2010 Operations Guide, see Considerations for Backing Up Virtual Machines on CSV with the System VSS Provider (https://go.microsoft.com/fwlink/?LinkId=196939). |
DPM error: An unexpected error occurred during job execution. (ID 104 Details: Element not found (0x80070490)) |
There might be a failed disk in the cluster. |
Repair or remove the failed disk in the cluster. |
Backup of Hyper-V virtual machines are stalled and no data transfer is happening. |
TCP Chimney Offloading maybe active. |
