In short, when we attempt to attach an existing disk to a new VM Azure woun't allow it as Azure seems to think the disk is still connected to an active VMeven though we shut it down, detached the disks and deleted the VM.
In short:
We had a server with three disks attached (1 x OS and 2 x data).
Shut down this server - Azure reported sucsess
Detached both data disks - Azure reported sucsess
Deleted the VM - Azure reported sucsess
Created a new VM - Azure reported sucsess
Attempted to attach existing data disks - Azure did not show them as available
After some digging around we saw Azure thinks the disks were still connected the the deleted VM
Please can someone in Azure support detach these disks so we can mount them to the new machine as we need the data from the disks.
I've tried Powershell and whilst I can see the disks I can't access the deleted VM to detech the disks - Powershell says the disks are attached to a running VM!
