Fixed In Version: vdsm-4.13.2-0.14.el6ev
Doc Type: Bug Fix
Doc Text:
Previously, the vmHotplugDisk action would fail with the error "VolumeError: Bad volume specification". This was caused by a multipath race condition that would result in a situation in which multipath was not given enough time to create the /dev/mapper entry for the LUN on the host on which the virtual machine was running. Now, the logic used to scan for device visibility has been revised so that multipath has the time required for creating the /dev/mapper entry for the LUN on the host on which the virtual machine is running.

Nir, please handle the backporting.

Remove upstream patches.
Comment 4 Aharon Canan 2014-05-07 14:48:44 UTC 
Verified using is36

Verification steps:
1. create 2 unattached LUNs and a VM
2. attach one of the LUNs when the VM is down
3. start VM and install OS
4. attach another LUN and check VM can access it.
