Hyper-V VMs failing to replicatio to Azure Site Recovery

Dylan Walkden 0

Hi folks,

I have a Hyper-V host that has been replicating it's two VMs to Azure Site Recovery successfully for the last year. However it has started failing with the following error logged in event viewer for both VMs:

Source: Hyper-V-VMMS

Event ID: 32022

Hyper-V could not replicate changes for virtual machine 'AppServer': The connection with the server was terminated abnormally (0x00002EFE).

In Azure the following error is logged:

Error ID

68501

Error Message

The virtual machine couldn't be replicated. Provider error

Replication for virtual machine 'AppServer' is in error. Fix the error(s) and resume replication. Possible causes

Replication errors occurred for virtual machine 'AppServer' in cloud/site '' because of issues with connectivity to Azure storage.

If Identity is enabled on the Recovery Services Vault, please make sure the log/target Azure storage account has the necessary permissions to access the storage account

a) Go to your Storage account -> Access Control (IAM).

b) Add the below role-assignments (for ARM based storage account) to the Recovery services vault.

    1) "Contributor" and,

    2) "Storage Blob Data Contributor" for Standard storage or "Storage Blob Data Owner" for Premium storage

Fix any issues in the Event Viewer logs (Applications and Service Logs - MicrosoftAzureRecoveryServices) on the Hyper-V host server and resume the replication.

Unfortunately the recommendations in the Azure error report are too vague for me to apply, but I have made sure that the Site Recovery client is up to date and tried a reinstall with no improvement.

@Dylan Walkden Sorry for the delayed response!

The error IDs: 32022 and 68501 indicates issue with permissions or connectivity to Azure storage.

Check if there are any network interruptions, firewall rules, or proxies that may be blocking outbound traffic to Azure.

Make sure that DNS resolution is working correctly on the Hyper-V host for Azure endpoints.

Ensure you are running the latest version of the Azure Site Recovery Provider and Recovery Services Agent on the Hyper-V host.

Try restarting the ASR-related services on the Hyper-V host. These services are:

Microsoft Azure Site Recovery Provider

Microsoft Azure Site Recovery Coordinating Service

You can restart them via the Services management console or through PowerShell:
Restart-Service -Name "MARSAgent" Restart-Service -Name "SiteRecoveryProvider"

Regarding storage account permissions, you have already checked as per recommendations

If possible, try to disable replication and re-enable it.

If issue persists, the best option would be to contact Azure support by creating a support request. The ticket enables you to work closely with the support engineers and get a quick resolution to your issue.

Here is the link - https://docs.microsoft.com/en-us/azure/azure-portal/supportability/how-to-create-azure-support-request to create support case.

Hope this helps. Let us know if you need any help (technical or assistance in reaching out to support)
