I have HP BL460c Gen9 blades with BCM57840 NetXtreme II 10/20-Gigabit Ethernet via a HP Virtual connection. In my ovirt 4.1 environment I have fibre channel working great. However in the new environment that I want to bring the data domain over too ultimately, I am having issues with ovirt interfering with the hosts ability to see the Fiber Channel storage. If i build a clean CentOS 7 installation and get my FCoE module installed and Fiber channel set up on my appropriate interfaces, it works and sees the fiber channel interface every time I type fcoeadm -i, I can reboot a million times, does not go away. However once I turn it into a oVirt 4.2 node and add it to my environment and reboot the blade it is hit or miss if fcoeadm -i is going to return interface information. If I then type "systemctl restart network" my fiber channel comes online, but I should not need to do this. I can see in my dmesg logs that the fiber channel is initializing on boot.

[ 39.516654] bnx2fc: [06]: FCOE_INIT passed Reminder I have not added a FC storage domain yet, because I need to turn off and detach the domain from the old 4.1 environment first. However that should not keep the fiber channel interfaces from coming up... And I need to know its working before I do that. Below is what an fcoeadm -i should return when it seems to be working. ____________________________________________________________________________________________________ fcoeadm -i Description: BCM57840 NetXtreme II 10/20-Gigabit Ethernet Revision: 11 Manufacturer: Broadcom Limited Serial Number: 5CB901C7EE00 Driver: bnx2x 1.712.30-0 Number of Ports: 1 Symbolic Name: bnx2fc (QLogic BCM57840) v2.11.8 over eno51 OS Device Name: host10 Node Name: 0x50060b0000c27a05 Port Name: 0x50060b0000c27a04 Fabric Name: 0x1000c4f57c218ff4 Speed: unknown Supported Speed: 1 Gbit, 10 Gbit MaxFrameSize: 2048 bytes FC-ID (Port ID): 0x0a025c State: Online Description: BCM57840 NetXtreme II 10/20-Gigabit Ethernet Revision: 11 Manufacturer: Broadcom Limited Serial Number: 5CB901C7EE00 Driver: bnx2x 1.712.30-0 Number of Ports: 1 Symbolic Name: bnx2fc (QLogic BCM57840) v2.11.8 over eno52 OS Device Name: host11 Node Name: 0x50060b0000c27a07 Port Name: 0x50060b0000c27a06 Fabric Name: 0x1000c4f57c21979d Speed: unknown Supported Speed: 1 Gbit, 10 Gbit MaxFrameSize: 2048 bytes FC-ID (Port ID): 0x14037b State: Online ____________________________________________________________________________________________________ However if I reboot the node from the ovirt console and wait a few minutes after it has rebooted then type fcoeadm -i I get the following. fcoeadm -i fcoeadm: No action was taken Try 'fcoeadm --help' for more information. it is not until I perform a systemctl restart network, that I get the correct output from above. Any help or insight into fiber channel with ovirt 4.2 would be greatly appreciated. -- Jacob Green Systems Admin American Alloy Steel 713-300-5690
