similar to: NPIV storage pools do not map to same LUN units across hosts.

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 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

Hello, I am trying to find out a best practice for a specific scenario. First of all I would like to know what is the proper way to set up multipath, who should care about it the host or the guest. Right now I have a setup where I have one multipath which sets my host to boot from FC SAN. I have another multipathed LUN in the host which is essentially a dm which I attached to a guest, however

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

Hi! Got a couple of storage questions here. I'm a storage guy, running a new project, and just started with libvirt, but have been using qemu/kvm on other platforms before, as well as oVirt. So, my questions here: I started with creating a vhba, and that went fine, I could see it on the storage side logging in to the target with its wwn. My next step would be to make it persistent, and

Hi, i''m having problems attaching disks from a fc-san to a solaris 10 guest. xen host ist a opensolaris box "SunOS node1 5.11 snv_127 i86pc i386 i86xpv". my xen guest is named pg4. this command works fine. virsh attach-disk pg4 /dev/dsk/c8t600A0B800029D69A000013CA4B00E1ABd0 hdb and before i was able to import this volume as a zpool on the xen host - so connection to this

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 resources of dom0

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.

Hi all. We developped a pv-scsi driver that we refered Fujita-san''s scsi-driver and blkback. (see, http://www.xensource.com/files/xensummit_4/Xen_Summit_8_Matsumoto.pdf) The pv-scsi driver''s feature is as follow: * Guest has dedicated SCSI-HBAs of Dom0. * Guest can send scsi_cdb to the HBAs. * Guest recognises the HBAs from hostno of xenstore. Currentlly, We are

Seems like different libvirt versions generate a storage volume name in different format. We would like to learn how libvirt names a storage volume under a block based storage pool. So that we may properly extract the LUN identifier out of the volume name for now and in the future.

Hi all, Here is the situation: I have 2 nodes MDS1 , MDS2 (10.0.0.22 , 10.0.0.23) I wish to use as failover MGS, active/active MDT with zfs. I have a jbod shelf with 12 disks, seen by both nodes as das (the shelf has 2 sas ports, connected to a sas hba on each node), and I am using lustre 2.4 on centos 6.4 x64 I have created 3 zfs pools: 1. mgs: # zpool

Hi, I'm using libvirt 0.8.3 on Fedora 14 (as I wrote earlier, I'm having some trouble updating to the newest version), and I'm having problems getting iscsi and mpath storage pools to work in a usable and consistent manner. I have two storage pools defined on the host machine, one for raw iscsi- devices and one for those same iscsi devices device-mapped by multipath. They look

Hi All, I am having problems with a kickstart install of CentOS 8 When I try to do a completely automated install using PXE/UEFI it get to the point where it reads the kickstart config file. Then I see the following message "kickstart install Started cancel waiting for multipath siblings for nvme0n1" This is what I have in the kickstart file # Clear the Master Boot Record zerombr #

I have run into a problem attempting to attach the seventh virtio-scsi device to a RHEL 6.4 Guest from a RHEL 6.4 host running libvirt version 0.10.2-18. I have a guest that is running RHEL6.4 where I can attach disks sda(boot), sdb, sdc, sdd, sde and sdf but when I try to attach sdg the virsh attach-disk command fails with the error: error: Failed to attach disk error: internal error Unable to

Hi. I've been waiting to hear more about current wine news other than from the most recent update. I always enjoyed reading the WWN talking about strategies to build a project to get Direct X 9 or 10 working and updates on the next wine meeting. Google summer of code (which is coming up soon). So I'm just curious, when is the next one coming out? Thanks, Ron

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. On sles11, after changing the script

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

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.
