Hi, Deployment over more than one path is currently not supported. There is a request for it: https://bugzilla.redhat.com/show_bug.cgi?id=1193961 I can't think of a way for manually change to dual paths and keep the VM running without interruptions. Adding Simone and Nir who might have an idea.

The scenario of manually connecting the hosted-engine host to several paths wasn't tested before, but by theory it should work. As you said, the host should be set to global maintenance, disconnected from the single iSCSI session [1] and reconnected to the dual paths [2]. Then host re-activation.

Yes, you're right. # The following are used only for iSCSI storage iqn= portal= user= password= port= Simone, what do you think, will it be possible to add targets in hosted-engine.conf as a workaround?
