I believe I have found the relevant error in the engine.log.

So my question is how do I delete that already existing Logical Volume
safely, so that I can move a disk from my iscsi to the FC. This VM used
to exsist on the FC before I migrated which is how I ended up in this
situation.

Any thoughts on how I remove an un-imported VM from my FIbre
Channel storage? I cannot move my working VMs back to the FC, and I
believe it is because the older un-imported version is creating conflict.

Ok, so here is the situation, before moving/importing our primary
storage domain, I exported a few VMs, so they would not need to go
down during the "Big migration" however they are now residing on some
iscsi storage, now that the Fibre Channel storage is back in place, I
cannot move the disks of the VMs to the Fiber channel because their
is an unimported version of that VM residing on the Fibre Channel. I
need to delete or remove the VM from the Fibre Channel so I can move
the working VM back to the Fibre Channel.
I hope that makes sense, but essentially I have a current duplicate
VM running in iscsi that I need to move to the fibre channel. however
because the VM used to exsist on the fibre channel and has the same
disk name, I cannot move it to the fibre channel, also it seems odd
to me there is no way to clear the VMs from the storage without
importing them. There must be a way?
Thank you.

Hey wanted to thank you for your reply, and wanted to let you know
that late after I sent this email, my colleuege and I figured out we
needed to enable the FCoE key in the ovirt manager and tell ovirt
that eno51 and eno52 interfaces are FCoE.
However I ran into another issue. Now that our Fiber channel is
imported to the new environment and were able to import VMs, we have
some VMs that we will not be importing, however we see no way to
delete them from the storage in the GUI. Or I am just missing it.
*TLDR*: How does one delete VMs available for import, without
importing them from the storage domain?
Thank you.

Any help or insight into fiber channel with ovirt 4.2 would be greatly

Hello Jacob,
we're running a cluster of 6 HP BL460 G9 with virtual connect without issues.
[root@kvmsv003 ~]# dmidecode | grep -A3 '^System Information'
System Information
Manufacturer: HP
Product Name: ProLiant BL460c Gen9
Version: Not Specified
We've, anyway, a different kind of CNA:
[root@kvmsv003 ~]# cat /sys/class/fc_host/host1/device/scsi_host/host1/modeldesc
HP FlexFabric 20Gb 2-port 650FLB Adapter
But i see is running the same module you're reporting
[root@kvmsv003 ~]# lsmod | grep bnx
bnx2fc 103061 0
cnic 67392 1 bnx2fc
libfcoe 58854 2 fcoe,bnx2fc
libfc 116357 3 fcoe,libfcoe,bnx2fc
scsi_transport_fc 64007 4 fcoe,lpfc,libfc,bnx2fc
[root@fapikvmpdsv003 ~]#
Since the fcoe connection is managed directly by virtual connect, i'm
not having fcoe informations shown with fcoeadm:
[root@kvmsv003 ~]# fcoeadm -i
[root@kvmsv003 ~]#
Are you sure you set up the right configuration on virtual connect side?
Luca
