What does ERROR_AZURE_DRIVE_DEV_PATH_NOT_SET mean?

Question

I am trying to attach a cloud drive on a live VM as described here http://msdn.microsoft.com/en-us/library/gg466226.aspx#bk_Storage but I get the error ERROR_AZURE_DRIVE_DEV_PATH_NOT_SET ?

What does this mean? I've tripled checked my config at it seems ok.

I am trying to connect the cloud drive in a Windows Service on a VM Role. I am already checking that the RoleEnvironment.IsAvailable is true so I think Azure is available.

Yes this did help. But not straight away.

First, I discovered that the FixMSI.js script from http://msdn.microsoft.com/en-us/library/gg466226.aspx#bk_Install was failing. For some reason $(BuiltOutputPath) was empty. I did it relative to the $(ProjectDir) instead.

It then failed with a different error (and much earlier). CloudDriveException 0x80070103 which you have pointed me to the article for.

Now it attaches ok. The strange thing now is that the device has a warning when the vm starts (but only when hosted in azure), I have to manually go into the vm on azure and update the driver to get it to work. Obviously, this is not ideal. the VM Image itself seems fine when hosted in HyperVisor

Answer 3

Hi,

Try to replace "$(BuiltOutputPath)" to "$(BuildOutputPath)" to see if works.

Hope this helps.

Unfortunately that also doesn't work. I am ok for now using project dir, so no biggie. More worrying is the fact that my vm on azure always needs me to fix the wa miniport device even though it was installed ok in hypervisor. Going to raise this as another topic though.
