vdsm log

Description of problem:
When creating a LUN on the iscsi storage and then performing send targets on the host it requires to run 'vdsClient -s 0 getDeviceList' in order to be able to create storage domain based on the device. 

Version-Release number of selected component (if applicable):
vdsm22-4.5-63.20.el5_6

How reproducible:
Always using REST API 'createStorageDomain'

Steps to Reproduce:
1. create LUN on storage server
2. perform send targets on the host
3. using REST API try to create storage domain
  
Actual results:
The create storage domain action roll-backs and the vdsm log syas: 'No physical volume label read from /dev/mapper/18dbe63c6-3864-43ca\n  Failed to read physical volume'

Expected results:
Should create storage domain iscsi

Additional info:

discoverSendTargets does not get a list of LUNs!
It is not intended to refresh the storage by any means.
This is working as designed.
