Doc Text:	Cause: When removing a VM with its disks, shareable direct LUNs are also removed. Consequence: Other VMs that might use these disks can no longer do that because they were removed. Fix: Shareable direct LUNs are not removed in any case (just like disk images). Result: Other VMs that might use these disks can still use them.	Story Points:	---

Description Idan Shaby 2015-06-23 08:23:27 UTC

Description of problem:
When removing a VM with its disks, shareable LUNs are also removed.

Version-Release number of selected component (if applicable):
c6f0fbf9b04c42f31a57c1c54f133059755bfb6b

How reproducible:
100%

Steps to Reproduce:
1. Create a direct LUN and mark it as shareable.
2. Create a VM and attach it the LUN you created.
3. Create another VM and attach it the LUN you created.
4. Remove the first VM using the webadmin (with the "Remove Disk(s)" check box checked).

Actual results:
The direct LUN is removed, and the second VM remains with no disks.

Expected results:
It shouldn't be removed since there might be other VMs that use it (like in this case).
