Hi All

As i was referring to the following link
http://lists.xensource.com/archives/html/xen-devel/2007-06/msg00996.html

but i can't see this work in official xen 3.2.
Is it still in review?

Or can i use the same patches to perform some NPIV task.


thanks in advance for any help

I think I've seen activing reviewing of this patch set fairly recently so 
presumably it's still being worked on.  It doesn't look like it's made it 
into 3.3, so I guess 3.4 would be the soonest we'd expect it...

If you're willing to try experimental software you could probably patch the 
code yourself - you might need to be prepared to do some merging in places if 
the Xen tree has diverged from the state that the patches expect...

You should try to make sure you have the most recent patches possible - I'm 
sure they've been updated several times since the mailing list post that you 
found.

Cheers,
Mark

Actually, the PVSCSI *was* mentioned in the 3.3 release announcement so I 
think you should find it there...

The header file seems not to have made its way into xen/include/public/io/ 
along with the other front/back interface definitions.  It is in the XenLinux 
copy of that directory, though, which I hadn't checked.

3.3 is probably worth looking at, then ;-)

Cheers,
Mark

Hi Tej-san Mark-san and all,

Unfortunately, the pvSCSI driver for Xen 3.3 does not support FC
transport layer functionality. I consider that at least new export 
mode, which exports whole physical SCSI tree under a HBA to guest 
domain, is needed. (FC transport functionality assumes physical 
topology, I think.)

Best regards,

Actually i am still at compilation and building stage of xen 3.3 and
will get back  on this.
Currently we are using the patches indicated in my previous post. i
could get the following.
1. I am able to access and see all the disk on SAN in dom0 i.e. cat
/proc/scsi/scsi list all the disk.
2. domU could not able to see that FC HBA driver itself, i will try
with directly assigning the PCI device to domU (HTH)
Front-back arch. could not be the culprit because this arch. is
applicable to dom0 also.

so what i am missing?

thanks

Hi,

The ptaches you are using are very old, so I can't remember detail about
them. Only I can say is:

- "Attach" operation is needed in order to attach specfied HBA to 
  guest domain. (To do so, some information should be wriiten to
  xenstore. However, these patches did not contain tool to do it, 
  meybe, because the patches were just for RFC.)
- After that operation, you can see SCSI disks under the HBA as 
  /dev/sd?? on the guest domain.
- If you can successfully see the disks, you can see any information
  about FC transport layer at /sys/class/*.

Best regards,
