Azure VM failed to install Azure VM Agent

Question

I just created an Azure VM from a specialized disk. The VM boots up and looks to run OK, but can't rdp. After researching looks to be related to the VM Agent.
executed Get-azVM on Azure PS and displayed the information at the bottom. Notice under VMAgent it shows: Code : ProvisioningState/Unavailable

So looks it failed to install the VM Agent when the VM was created. I guess because it is using an specialized disk. Found a post about fixing it offline. That will mean installing the agent on premises and uploading the disk again. Is there a way to explore the disk content and install ofline in Azure? Am trying to avoid uploading again.

Thanks,

Carlos

Answer 1

I think, you can try installing the vm agent in offline mode: For this, you have to create a different VM and attach the special disk as a secondary disk to the new VM. There is a troubleshooting step to be followed as explained in below documentation:

Answer 2

Yes, did that. I didn't find an option to do with the VM in online mode. Will test later tonight.
