FCoE wont initialize on reboot oVirt 4.2.
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.

However that should not keep the fiber channel interfaces from coming up... And I need to know its working before I do that.

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. On 11/28/2018 01:26 AM, Luca 'remix_tj' Lorenzetto wrote:

Hello Jacob, to be honest i don't know. I'd import them without powering on and then delete the vm. Removing is a complex activity since there are metadata and other thing written on OVF_STORE disks and other places. Luca On Thu, Nov 29, 2018 at 5:14 AM Jacob Green <jgreen@aasteel.com> wrote:

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. On 11/28/2018 10:14 PM, Jacob Green wrote:

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. On 11/29/2018 03:12 PM, Jacob Green wrote:

Ok so two things, one I found this bug report which I believe is relevant to my issue. *https://bugzilla.redhat.com/show_bug.cgi?id=1497931* * * And secondly I found using a tip from that bug report that I in fact have two identical LVMs. I need to remove the one that already exists on the FC, so I can move the one from the iSCSI to the FC. "*bb20b34d-96b9-4dfe-b122-0172546e51ce* 0e4ca0da-1721-4ea7-92af-25233a8679e0 -wi-a----- 80.00g Fibre Channel /Un-imported old version of the VM/ *bb20b34d-96b9-4dfe-b122-0172546e51ce* b9cce591-fed5-4b59-872b-41a9fecb607e -wi------- 80.00g" iSCSI Current good version of the VM that I would like to move back to FC. So there must be a manual way to do this? And I would then need to remove the record of the VM from the FC OVF store? I am having trouble finding good documentation on how to do this.

__________________________________________________________________________________________________________________________________________________________
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 appreciated.
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
