Direct access from VM to LUN over FC with multipathing
Hi,
Some body know how to attach a LUN directly to an VM?
Is two node pool with storage over multipath FC tied by an Qlogic hba.
I''m using lvmohba with out problems, but I want to assign it directly to VM
to increase the throughput.
Thanks for the advice.

Automatically detecting LUNs without a reboot
Hi everybody.
I have an HP StorageWorks array connected to one of my servers,
connected via an LSI controller (lspci reports: SCSI storage controller:
LSI Logic / Symbios Logic SAS1068E PCI-Express Fusion-MPT SAS (rev 08))
on an HP DL385 running CentOS 5.5 x86_64.
I have set up multipath and all is working but, when I create a snaphost
and export it as a new LUN from the HP web interface, it

Multipath-root (mpath) problems with CentOS 5
Hi list!
I have a server with dual port Qlogic iSCSI HBA. I set up the same LUN for
both ports, and boot the CentOS installer with "linux mpath".
Installer detects multipathing fine, and creates mpath0 device for root disk.
Installation goes fine, and the system boots up and works fine after the
install from the multipath root device.
After install the setup is like this:

Ang: Ang: Re: Ang: Ang: Re: Ang: Re: attaching storage pool error
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't

pvresize on a cLVM
Hi,
I'm needing to expand a LUN on my EMC CX4-120 SAN. (Well I already had done it).
On this LUN I had a PV of a cLVM VG. Know I need to run pvresize on it.
Has anybody done this on a cLVM PV ?
I'm trying to rescan the devices, but I can't "see" the new size. And,
googling on it I can only find RHEL5.2 responses.
Thanks in advance,

Qlogic HBA scanning issues with CentOS 5.1 ?
Hi,
I got few servers (IBM HS20,HS21 blades, IBM xSeries 3650 & others)
connected to a dual fabric san throught Qlogic HBA's (23xx, 24xx).
Multipathing is done with device-mapper-multipath.
On CentOS 4.x i can scan for new scsi devices without any problems, get
them up with multipathing & use them without any problems.
However, after i started installing CentOS 5.1 (did not

Re: attaching storage pool error
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

device-mapper multipath
I am attempting to get multipath working with device-mapper (CentOS
4.2 and 4.3). It works on EVERY install of mine from RH (also v4.2,
4.3), but the same multipath.conf imported to all my installs of
CentOS do not work. Note that I have tested a working 4.2
configuration file from RH on CentOS 4.2 and a working 4.3
configuration (it changed slightly) on CentOS 4.3. Neither worked. Our

Multipath pools - practical for use?
Hi all,
Writing up some Fedora documentation, and looking to figure out the best
way of mapping multipath network(!) LUNs to pools in libvirt.
ie Infiniband SRP LUNs, but would probably apply to Fibre Channel
equally as well.
There are two approaches I can think of easily:
a) Large LUNs (ie TB+) that are mapped to a host server as disk, with
each LUN being configured as an LVM

vhba and storage pool creation
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

multipath using defaults rather than multipath.conf contents for some devices (?) - why ?
hi all
We have a rh linux server connected to two HP SAN controllers, one an HSV200 (on the way out),
the other an HSV400 (on the way in). (Via a Qlogic HBA).
/etc/multipath.conf contains this :

How to support iSCSI multipath...
Hi Bootmeisters,
I am using gpxelinux.0 + sanboot.c32 to boot a diskless machine into Linux. I
would like to use device-mapper-multipath to provide fault tolerant access to
its root disk.
Although I am able to do this by hardcoding the additional paths in the initrd,
it would be better if the bootloader could pass the information in the iBFT
(iSCSI Boot Firmware Table). However, at the

Libvirt with multipath devices and/or FC on NPIV
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

Which bios is hvmloader using ?

when I boot my windows, the bios that is used is a qemu bios. I''m searching for the bios file on my system that is used by the hvmloader. I found bios files from bochs :

High Number of VMs
Hi, I''m curious about how you guys deal with big virtualization
installations. To this date we only dealt with a small number of VM''s
(~10)on not too big hardware (2xquad xeons+16GB ram). As I''m the
"storage guy" I find it quite convenient to present to the dom0s one
LUN per VM that makes live migration possible but without the cluster
file system or cLVM
