An automation scripts that prompts you is a letdown, to say the least.
A typical example of such an event is the question you get when you try to unmount a CD or DVD drive from a VM. Some Linux guest OS will place a lock on the CD or DVD, and vSphere will ask you if you want to bypass this lock. And your script just hangs there, waiting for you to reply 🙁

Lately I have been playing around with the new Storage related features in vSphere 5. One of the novelties is that you can now unmount a VMFS datastore and detach a SCSI LUN through the API.

Nice feature, but what for those of us that want to automate this ?
Update October 28th 2012: Take into account that the datastorecluster is not connected to a host that is part of a cluster. Skip the HA heartbeat test.
