In this case. How are the virtual disk images then made available for the VMs on the other host? - If the first host fails, the engine will get started on the other host. Will the engine deal with the fact, that now the iSCSI storage domain has to be accessed using the other host. Or is iSCSI just not suitable for this kind of usage. - Has the self hosted engine to use a different iSCSI lun than the storage domain?
