Maor, I see two patches merged to the 3.5 branch.
Are there any other patches required, or should this be moved to MODIFIED?

There is one more patch that need to be merged before moving this to modify

Moving to NEW for now until a proper solution will be resolved through gerrit

Maor, you wrote at the doc text:
"Result: 
Adding an API for storage domain which called isattached
IMPORTANT: Executing this API will cause the Storage Domain to disconnected from the Host executing this API" 

does this mean that everytime a user executes 'isattached' and expects to get 'True' or 'False it will cause also the Storage Domain to disconnected from the Host executing this API" ?

Maor, this function looks like a bug, no sane user will ever use it.
just tried to "query" 'isattach' operation on a storage domain.
the operation returned 'True' and after on second the whole dc became None-Responsive (see image and logs) and ERRORs and Tracebacks on all logs

Tested using rhevm-3.5.1-0.1.el6ev, vdsm-4.16.12-2.el7ev.x86_64
