Hi folks,
I have a HyperV host that has been replicating it's two guest VMs to Azure Site Recovery. However it recently logged the following error in the Hyper-V-MMS Admin event log for both VMs:
Event 33692: Replication provider failed with error code 0x8079000A when processing the replication request for virtual machine '<machine-name>'
After this error replication for both VMs is in a critical state and attempts to resume fail with the following error logged in the Hyper-V-MMS Admin event log:
Event 32022: Hyper-V could not replicate changes for virtual machine '<machine-name>': The system cannot find the file specified. (0x80070002).
I can't find any reference to the first error code (0x8079000A) anywhere online and the second error makes me suspect that something failed and cause a HRL file to be lost. I would really like to know what the original failure was and if there is a way to recover without simply deleting and recreating the replicas.

I see that you have Hyper-V host that has been replication 2 guest VMs that started erroring out and failed replication. The issue seems like corruption or incomplete installation issue.
Could you please delete the replication appliance and start over again?
There is a similar issue discussed here - https://learn.microsoft.com/en-us/answers/questions/1188769/replication-failing-from-hyper-v-to-azure reinstallation of replication appliance seems to have resolved the issue.
Let us know how it goes!

The discussion you linked to was actually started by me, so I am familiar with that one.
Deleting and recreating the replication was the final solution and I am prepared to go down that route if we need to, however there is an unknown cause that I would really like to understand first. Are you able to shed any light on the error that originally started the problem?

2023-12-06T13:36:14.17+00:00 @Dylan Walkden We need to investigate the logs to better understand the cause of the issue. However, the scope of support through public forum is limited (cannot access customers/clients) set up. I would suggest reaching out to Azure technical support team by raising 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.
Let us know if there are any challenges contacting Azure technical support team.

2023-12-07T03:54:30.2666667+00:00 I'm afraid that I'm the Microsoft Partner of the affected tenant. If we try and log a support request from our client's account they receive a response saying they need to contact their Microsoft Partner (myself). If I try and log a support request on their behalf through the partner portal there is no option for Azure Site Recovery in the "Service type" selector.
This means as a Microsoft Partner my only option is the public support forums, which is less than optimal.

2023-12-07T06:03:10.6766667+00:00 @Dylan Walkden Sorry for the inconvenience. If you are not getting option for Site recovery, you can either choose Azure backup or Azure Migrate and create a support request and leave a note in the issue description to route the ticket to Azure Site Recovery team.
Let us know how it goes. If there are any challenges, please reply to this post.

2023-12-12T05:48:44.9533333+00:00 With Christmas around the corner I'm afraid I'm too busy to be able to juggle a phone support call, we've made the decision to just delete and recreate the replication to get it back up and running ASAP. If the issue occurs again we'll go through the steps to raise a support ticket over the phone.
Thank you for you help Sadiqh.
