So if you have 4 tasks via your iSCSI volume replication and the error message is indicating that LV0002 has an Unknown state but shows it is consistent then the other 3 are ok. I would check the Destination server LV0002 to make sure it is properly set for scsi ID, LUN, Target name and make sure it is enabled as well as the Volume Replication manager to make sure that it is set to destination. Also on the Source. All the other 3 iSCSI Volumes are not showing errors so it must be something with the LV0002.
