How to connect the fiber channel (multhipath) disk to the VM?

During runtime attaching the disk works with the following command:

virsh# attach-disk <domain> /path/to/disk/ vdX

The guest sees the storage as /dev/vdX but if I reboot the host, the configuration is lost and the storage did not remain attached to the guest.
When trying to add the command attach-disk parameter --persistent, I get an error:

On the server host:

virsh # attach-disk <domain> /path/to/disk/ vdX --persistent

error: Failed to attach disk
error: 
Requested operation is not valid: cannot modify the persistent configuration of a domain
