...;'0''/> </console> <input type=''tablet'' bus=''usb''/> </devices> </domain> in /dev/dsk i also only see this one file based disk. Can you help me with this? The second option i found useful and but bad documented is npiv. I create a virtual port for the 2 fc-hbas in the machine via fcadm create-npiv-port -p 2000000000000001 -n 2100000000000001 2100001b321fbc18 fcadm create-npiv-port -p 2000000000000002 -n 2100000000000002 210000e08b947697 and the result looks fine: global: root@node1:~ > fcinfo hba-port HBA Por...

I apologize if this is a little off-topic, but it does relate to Xen and using NPIV on Xen, so I think this is an appropriate forum for the question. I''ve recently begun using NPIV for a couple of Xen PV domUs rather than traditional disk passthrough. My reasons are primarily for performance - I''m hoping that NPIV has lower overhead and lower reliance on the re...

Hello all, I''m doing some testing with Xen and NPIV disk on the platform SLES 10 SP2 and SLES 11 (xen 3.3). On SLES 10 sp2, I have not encountered major problems during the tests (exept with live migration). I was able to attach a disk with the command "xm block-attach npiv:..." an I am also able to start a VM using a bootable NPIV disk....

I'm missing something. The purpose of NPIV (as I understand it) is to give a guest OS an HBA that it can scan, play with new luns, etc all without making changes to the physical server(s) the guest is living in currently. However, I can't find a way to either have the guest's XML config create the HBA or for the physical server to...

...evice name is persistent across all hosts, but is that the right approach. Here is another question that is bugging me. I have FC HBA-s on all hosts and I would like to make a HBA visible through my guest. I stumbled upon a bug that is documented in redhat's bugzilla that attempted creation of NPIV on pci_0000_blah_blah instead on the scsi_hostX device, but I fixed that easily in the xml and although virsh doesn't seem to think I completed the nodedev-create NPIV_for_my_FC.xml the device is seen as a child in nodedev-list and what is more important the WWN are seen on the SAN switch. So t...

Hopefully someone can help get multipath working inside a domU. I'm using Xen 4.2.3 on a SLES 11 dom0, and both a SLES11 domU and a CentOS 6 domU. I'm using NPIV to connect my SAN disks to my domU, and, due to the way my SAN presents the LUNs, need to use multipath inside the domU. I've tried this on both SLES11 and CentOS6 with pretty much the same result. The root issue seems to be that no "disk identity" (SCSI ID/WWID/etc.) is passed thro...

Hi again! Need to add here, since I been investigating a bit further, that it seems to be possible to add an NPIV vhba to the guest, using vdsm hooks. I've seen the reference to "host device assignments", which Dan pointed me too, but I didn't really understand the meaning of it at that moment. It would be interesting to hear from someone that have been doing it, how it would look like in th...

Can anyone point me to a source for the correct syntax to add an npiv disk to a domu? I thought it was disk=[ ''block-npiv:/wwn,xvda,w'' ], I tried just npiv:/ and that didn''t work at all.

Is this possible: I would like to have a VM use a FC LUN exported to a virtual wwn (using NPIV) as its primary disk. I was thinking there might be a mechanism to say VM, boot using a LUN with this vwwn as your primary disk? Thanks in advance. -- --------------------------------------------------------------------- Eric Ross HPC Systems Administrator Argonne National Laboratory Leadershi...

Hi! Report from my multipath tests today. My test virtual machine, that runs from an NPIV pool, is not able to use multipath. When I pulled the cable from one of the targets, it crashed. But, strangely, it could boot up again on that other path, that it just crashed on. That tells me it can use both paths, and is not limited to one of them only, but because the multipath layer isn...

I''m using Xen with SLES10 and am using NPIV to attach FC SAN disks to my domUs. I''ve resize one of the disks on my SAN and I''m wondering if there''s a way to force Xen to rescan/resize the block device without shutting down the domU or unmounting the volume. Thanks, Nick -------- This e-mail may contain confide...

Hi all, I found a article about Hyper-V virtual Fiber Channel, I think this will make Failover Cluster work if KVM has the same feature. http://technet.microsoft.com/en-us/library/hh831413.aspx Hyper-V uses NPIV for virtual Fiber Channel, I have read some article about KVM NPIV, but how can I config it with libvirt? Any body can show me some example? On Wed, Aug 14, 2013 at 2:33 PM, Timon Wang <timonwst@gmail.com> wrote: > Thanks, i have tried virtio-scsi and LSI SCSI controller, by using a >...

Hi, I'm trying to attach a host FC HBA to VM (NPIV). Running ovirt 3.5 on CentOS 6.7, libvirt-0.10.2-46.el6_6.6.x86_64, I created vHBA using nodedev-create command - see below HBA and vHBA.

Thanks for John Ferlan's lots of internal feedbacks, I believe it's more readable, and better orgnized now. Should we create a page for it under http://libvirt.org/deployment.html or add it in WIKI? ========================================== NPIV in libvirt NPIV (N_Port ID Virtualization) is a Fibre Channel technology to share a single physical Fibre Channel HBA with multiple virtual ports. Henceforth known as a "virtual port" or "virtual Host Bus Adapter" (vHBA), each virtual port is identified by its own WWPN (Word Wi...

Before posting it to WIKI or somewhere, I want to see if there is any suggestions on it, or if I missed something. ============================================ How to use NPIV in libvirt I planned to wrote a document about how to use NPIV in libvirt after more features are supported, but it looks like I can't wait till then, got lots lots of questions from both the bugs and mails. So here we go. The document tries to summary up the things about NPIV that libv...

Thanks. I have read the link you provide, there is another link which tells me to pass a NPIV discovery lun as a disk, this is seen as a local direct access disk in windows. RAC and Failure Cluster both consider this pass through disk as local disk, not a share disk, and the setup process failed. Hyper-v provides a virtual Fiber Channel implementation, so I wondering if kvm has the same so...
