Question

0x800423F2

Greetings,

We are seeing the following as possible cause for Error ID 153051 in Event Details for the Replicated Item (it is an Azure VM):

VSS writer ASR Writer failed with error 0x800423f2 during After DoSnapshotSet phase on the source machine.

We restarted the VSS service responsible for ASR Writer, but the Replicated Health of the item continues to appear in Warning status.

Attached is the screenshot from "C:\Program Files (x86)\Microsoft Azure Site Recovery\agent\Application Data\ApplicationPolicyLogs\vacp.log*".*

Request your help to sort this out.

Thanks in advance.

Regards

Hello, @Yagnavalkya Siva Prasad Manchi !

Thank you for sharing the error codes and the log. Can you tell us a bit more about your setup?

Have you patched/updated your VMs recently?

What OS are you using on your VM (is this SQL Server)?

Are you using third party software (like ShadowXafe)?

Was another backup taking place?

Have these been rebooted recently?

Exactly the same here, tried a number of article suggestions online, but no succesful resolution.

Hi Kobulloc,

Our has kicked into working now, but I can answer the below for reference:

Fully patched and up to date

VM is 2022, SQL is 2019

No third-party software

No other backups (SQL takes backups, but at a different time)

Rebooted the night before, and every 2-3 weeks.

For reference, we had the issue ongoing for 1-2 months.

Thanks

In our case, the service 'Azure Site Recovery VSS Provider' was set to "Manual" rather than "Automatic" by default. After a change of the behaviour, replication health returned to normal/ healthy state.

Hello, @Yagnavalkya Siva Prasad Manchi (and @Martin)!

Edit: Solution from @Martin:

In our case, the service 'Azure Site Recovery VSS Provider' was set to "Manual" rather than "Automatic" by default. After a change of the behaviour, replication health returned to normal/ healthy state.

Why am I running into the VSS writer ASR Writer failed with error 0x800423f2 during After DoSnapshotSet phase on the source machine. error on SQL Server?

This is a question that has come up before and there are some troubleshooting steps you can take to address this:

What OS are you using on your VM (is this SQL Server)? There is a known issue with SQL Server 2008 R2.
Have you patched/updated your VMs recently? Some known issues have been addressed with older patches.
Was another backup taking place? If VSS was in use then it would cause a conflict that could cause this error.
Are you using third party software? This might cause a conflict with VSS.
Have these been rebooted recently? Rebooting can clear bad states on the VM that may be responsible for the error.

Edit: Solution above from Martin.
