[BETA] [HPE] Deploy VME worker failed

[miquel.mariano]

Hi everyone, I'm setting up a proof of concept (PoC) using the HPE VM Essentials plugin and I'm getting an error when trying to deploy the worker.

The VM deploys correctly to the VME cluster and responds to pings, but it ultimately fails.

Any ideas?

"Failed to connect to the worker core service: A credentials tag cannot be null or empty"

Hello,

Could you please reproduce the issue with the Debug log level enabled and share the platform service logs located at:
C:\ProgramData\Veeam\Backup\Plugins\HPEMORPHEUSVME\Veeam.HPEMORPHEUSVME.PlatformSvc.log

To enable Debug logging:
1) Open the appsettings.json file as administrator.
Location:
C:\Program Files\Veeam\Plugins\HPE Morpheus VM Essentials\Service
2) In the Logging section, set the log level to Debug.
3) Restart the VeeamHpeMorpheusVmeSvc service.
4) Reproduce the issue and collect the log file.
5) Afterwards, you may set the log level back to Info and restart the service again.

Additionally, it would be helpful if you could walk through the "Edit HPE Morpheus VM Essentials Server" wizard with Debug logging enabled.

Thank you!

Hi EvgenyBaev, thanks for your response.

Unfortunately, I'm using a Linux instance of VBR13 and your instructions don't fit my scenario.

However, I've been able to locate both the logs and the configuration file, but I'm unable to edit it with the veeamadmin user.

I am having the same issue, but with a Windows install.

I hope this helps.

You can temporarily enable root permissions for the appliance

I am having the same issue, but with a Windows install. I have the Debug logs. How do I send them? Sorry, I am new here...

I sent you a PM with my email address, if you want to send them to me.

[miquel.mariano]

Good. I have enable debug mode and try again the operation.

Here the Veeam.HPEMORPHEUSVME.PlatformSvc.log > https://miquelmariano.github.io/assets/ ... ormSvc.log

Here the worker logs > https://miquelmariano.github.io/assets/ ... 740242.zip

The tests start at 4:53 PM

Thanks you

Hello, miquel.mariano

Thank you for debug logs.

The issue happened when adding HPE Morpheus VME server to backup infrastructure.
When adding the server we create a service account on every cluster node which is managed by this server. That account is used for SSH connection to cluster nodes during backup in NBD mode.
In order to do it we call execution script request on HPE side.

In logs I see that the request was successful for the 1st and 2nd cluster node:
2025-12-02 18:49:44.3375 00021 [48867] INFO | [MorpheusController]: Successfully configured SSH access to the cluster host 1, IP address "10.10.10.81"
2025-12-02 18:49:45.0680 00019 [48867] INFO | [MorpheusController]: Successfully configured SSH access to the cluster host 2, IP address "10.10.10.82"

But it failed for the 3rd node:
2025-12-02 18:49:45.0680 00019 [48867] INFO | [MorpheusController]: Configuring SSH access to the cluster host 3, IP address: "10.10.10.83"
2025-12-02 18:49:51.3399 00019 [48867] ERROR | [MorpheusController]: Failed to configure additional settings for the HPE Morpheus VM Essentials clusters: Failed to execute the script: status Failed, exit code , error: , status message: : Veeam.Vbf.Common.Exceptions.ExceptionWithDetail: Failed to execute the script: status Failed, exit code , error: , status message:

As a result we haven't created service account on the 3rd node and haven't saved SSH credentials to VBR database.

I see later in logs that for master server (Morpheus):
2025-12-03 16:53:23.2501 00006 [441867] DEBUG | [DbProvider client]: ==> Response "Get" "https://localhost:6172/api/masterServers", "code: 200", duration: "13 msec", headers: "[]", cookies: "[]", body: "
"ServiceUserCredentialsTag\\\":null
which causes that error - A credential tag cannot be null or empty.

Could you please answer a few questions
1) Did you have any errors on Apply step when registering HPE VME server in VBR?
2) Has the server been registered in VBR if there were errors in session?
3) Is the 3rd node working - 10.10.10.83. Is it possible to ping it from VBR?
4) Have you tried to go through Edit HPE VME server wizard? Normally we have to check for missing SSH credentials and re-create them.

If editing doesn't help you can try to re-add HPE VME server to VBR and check logs for "Successfully configured SSH access" messages for all cluster nodes.

Meanwhile I will try to do reproduce similar behavior on my lab and share results. Looks like a bug on our side with managing such cases.

This resolved my issue - I am guessing that I had the same issue with my VME Server on a Windows-based install of Veeam B&R. I did get an error when adding my VME Server. It did add, so I rebooted both Veeam and my VME Server, and everything looked ok. I did have a VME host in maintenance mode at the time, and it was shut off. I have since removed that host, opened the properties of my VME Server in Inventory, ran through the wizard, and did not encounter any errors. I then ran a test on my Worker, and it finished successfully and much faster this time. I kicked off my backup job, and it has been running for a few minutes with no errors. Thanks for the quick response and for allowing me to piggyback off Miquel.

I see the same error in your logs that Evgeny mentioned:

Thank you, bent502

FYI. SSH credentials are used only in the beta version and will be removed in the 1.0 release.
