    • OMV 4 Fibre Channel SAN Multipath

      Hi all,

      I have set up new OMV Server on a Dell Poweredge Server Hardware wirth a Fibrechannel HBA and connected two IBM 3700 SAN Controller to it. I set up everything in debian and can see the configured disks in OMV but it is showning the disks twice, at it will not use the multipath driver. I use an Emulex HBA. Is there anything I am doing wrong?

      attached you will find output in console of harddisks.

    • Did you install the multipath-tools and kernel modules and then configure it? I've never set this up outside of VMware and don't have a way to test this.

    • You have them configured in /etc/multipath.conf? Sorry, this is completely different than VMware. So, I am just guessing based on little bits I found on google.

    • Is it at /etc/multipath/multipath.conf? I would think something would need to create it but maybe you need to create it. Not sure.
