Data Protector Granular Recovery Extension (GRE) and HP OneView don't play nicely together

Are you tearing your hair out about this mysterious error?

Http Error - 500 
{"message":"Unexpected error :There was a problem while sending query to service https://cellmgr.ifost.org.au:7116/dp-gui/grePlugin/GetMountProxies.jsp?newMachineTypeParam=MountProxy. Check that this agent is accessible."}

Then you are presumably trying to configure the HPE DataProtector Granular Recovery Extension (GRE) in version 9.05. And sometimes it works, and then.... it doesn't. Even when you haven't changed anything.

What's going on is that if anyone starts HP OneView on that Vsphere server, the GRE will start getting that error. The only workaround at the moment is to restart the Vsphere server (!) and try again, and hope that no-one looks at OneView.

Or uninstall OneView.

Or uninstall Data Protector VMware Granular Recovery Extension.

HPE's tracking code for this problem is QCCR2A65688, but at the moment it's still under investigation.

In the interim, just hope that you don't need to restore an individual file from a VMware-level backup because you will be manually restoring the VMDK, manually mounting it and then collecting the files out that you want.

You can also ditch VMware-level backups for the moment, install an agent and use file-level backups until it's resolved.

I'll update this blog post when a fix is released.
