Previously when adding a Fibre Channel storage domain through the Red Hat Enterprise Virtualization Manager administration portal, the installation disk was presented as a valid Fibre Channel disk for the storage domain. Selecting the installation disk could cause data corruption. Now, a pop-up with approval latch is displayed, preventing unwanted data loss.

RHEVM 3.0.2_0001-2
vdsm-4.9.6-8.el6
rhev-hypervisor-6.3-20120419.0.el6

How reproducible:
Always

Steps to Reproduce:
1.install rhev-h to FC lun
2.register to rhevm in an FC datacenter
3.create new storage domain using rhevh as the host to create
  
Actual results:

Expected results:
should filter the disk(s) where rhev-h is installed

I believe this is not specific to RHEV-H: if we install on a RHEL host which has mounted filesystems on its FC devices, vdsm would report these FCs as available for a storage domain. And although dangerous, this is not new and I do not think that it is a blocker.
Comment 3 Dan Kenigsberg 2012-07-02 13:21:05 UTC 
According to Eduardo, this is solved as part of

http://gerrit.ovirt.org/5515

which would report locally-mounted devices as "gray".
