Also noticed that /dev/disk/by-scsibus/* path does not exist as supposed
in cacheSCSIidentifiers() in the scsiutil.py so devs property is empty
while sr-probe and only general information returns. Does any patch
exist too?

Subject: [Xen-API] xcp-xapi devscan.py kernel support
I installed xcp-xapi on the Debian Wheezy and can't get LVMoHBA to work:
stderr: Traceback (most recent call last):

Can you please send devscan.py patch to support lvmohba in kernel 3.X.
I have attached the patch in question. It uses the right sysfs paths after
detecting the kernel version. It might not apply to your version but it may
help you make the change you require.
Also will in this case other lvmohba features will work smoothly in that case
on Debian, especially multipath?
It's unlikely you'll get LVM to work with your setup since we use a patched
version that accepts another option (--master) which affords us a different
locking mechanism to allow shared SRs. This option doesn't exist in the
upstream Debian LVM.
It may(!) be possible to get it to work if you remove the --master option from
the calls to lvm in the source and ensure that you are only using these SRs in
single-host pools. Again, your mileage may vary.
Hope this helps,
-Si
