Description of problem:
------------------------

When the "Name" of a host was edited while installation was in progress, the host ended up in Install Failed state instead of coming up. The following is from events log -

Version-Release number of selected component (if applicable):
--------------------------------------------------------------
Red Hat Storage Console Version: 3.0.0-0.14.el6rhs 

How reproducible:
-----------------
Consistently.

Steps to Reproduce:
-------------------

1. Create a 4-node RHS cluster and import the cluster using the Console.
2. While the hosts are being installed, edit the names of all nodes except one.
3. After a few moments all the nodes except the one whose name was not edited, will end up in Install Failed state. The node that was not edited comes up.

Actual results:
----------------
Nodes whose name was edited while installation was in progress, fail to install.

Expected results:
------------------
Node is expected to come up.

Additional info:
-----------------

When the cluster was imported without editing the names while installation was in progress, the nodes came up as expected. Find host-deploy logs from one of the nodes attached.
