<div>It's probably not the most tested path but once you have an engine you should be able to create an iSCSI bond on your hosts from the engine.</div>
<div>Network configuration is persisted across host reboots and so the iSCSI bond configuration.</div>
<div><br>
</div>
<div>A different story is instead having ovirt-ha-agent connecting multiple IQNs or multiple targets over your SAN. This is currently not supported for the hosted-engine storage domain. </div>
<div>See:</div>
