Given the timeline it will not make it to 3.6.2, deferring to 3.6.5 until we get an answer in late January

If the disk appears properly in the DB, doesn't a simple refresh of the GUI solve the issue?

Hi Sarvesh, 
Can you elaborate the steps to reproduce this. Does this happen to all attached disks? Does this happen the moment you attach the disks and start the VM or after a specific event?

Sarvesh, can you answer this question please?

This bug is probably a duplication of Bug 1044466 which was solved in 3.5.6. The bug is basically a faulted hotunplug at the host side, which reported a success back to the engine. in that case, the disk looks unplugged at the engine while it is actually still attached to the VM.

Currently we will close the as duplicate- if the issue persists after upgrading to 3.5.6, please reopen.
