Never mind. Installed a new updated brocade driver on the hypervisor, restarted the engine after after 10 minutes, the engine restored everything itself :-)

Dear All,

After we updated our hypervisors to :
vdsm-4.16.7-1.gitdb83943.el6.x86_64
vdsm-python-4.16.7-1.gitdb83943.el6.noarch
vdsm-python-zombiereaper-4.16.7-1.gitdb83943.el6.noarch
vdsm-xmlrpc-4.16.7-1.gitdb83943.el6.noarch
vdsm-yajsonrpc-4.16.7-1.gitdb83943.el6.noarch
vdsm-jsonrpc-4.16.7-1.gitdb83943.el6.noarch
vdsm-cli-4.16.7-1.gitdb83943.el6.noarch

We don't have access to our storage domain anymore. He jsut doesn't see the disks anymore...

I added the vdsm log and engine log. I'm clueless... BEfore he did see the storage domains, now after the system update he doesn't anymore...

Thanks in advance,

Kind regards,
Koen
