>>> I create vdisk, I present it to both hosts. Both hosts are seeing this disk.
So far good.
>>> However, when I create folder on one host on this shared disk, I don't see it on another.
This is terribly bad. You should not even try that. To allow simultaneous access of a disk from both servers over a file system, you need a cluster file system, like veritas. Microsoft does not provides a cluster file system so you cannot access the same disk simultaneously from both nodes with a file system.
Using raw device, and Oracle, you can. That means, you must not format the shared disk.
Por que hacerlo dificil si es posible hacerlo facil? - Why do it the hard way, when you can do it the easy way?
