... especially for SCSI paths where the multipathing is designed to be indifferent to both transport and network route between SCSI initiator and SCSI target? Don't they both result in one path per path group for a given SCSI logical unit as long as the node name is defined to be the "host number/channel number/target id" triple setup by sysfs_devinfo in libmultipath/discovery.c? BTW, this is an example of the SCSI affinity I was mentioning in my previous submission.
