Install oVirt with directly-attached SCSI devices
Hi all! My name is Paolo and I'm the sysadmin of the research group (infosec) where I work. Recently our infrastructure was updated and I'm planning to use oVirt as virtualisation manager. The new "toys" they gave me are - HP DL360G9 (x2) - HP MSA1040 (double controller with mini SAS connection) By exploring the oVIrt documentation, seems that the best solution for storage management would be having something like NSF, iSCSI and so on. Unfortunately, LUNs exposed by our MSA1040 are recognised by the two DL36G9 as directly-attached SCSI devices. I asked Google and I found this old post from the far 2013 http://lists.ovirt.org/pipermail/users/2013-November/017924.html that seems to be very similar to my case and the scenario is not rosy... :-( Is now, in 2016, something changed? Have you something to suggest? Many thanks, Paolo -- PAOLO SMIRAGLIA

Do you see the luns exposed by this storage on both hosts? The output of "lsblk" and "multipath -ll" may be helpful. If you do, you can treat them as FC storage, and create a FC storage domain with these luns. Nir

Hi Paolo, If your storage is detected by multipathd as a multipath capable device (it should, even if connected through only one connection), oVirt will detect it as "fibre channel" storage and selecting that as the storage type should work. We use a similar setup (with Dell powervault storage) and haven't had any problems with it. Regards, Rik -- Rik Theys System Engineer KU Leuven - Dept.

Thank you Nir and Rik for your hints! I'll check them soon. Bests, Paolo On 04/09/2016 09:03 PM, Rik Theys wrote:
