Not sure what this means.  The group-by-node-name policy implies assigning
paths with similar node name attribute to the same group.  For SCSI, seems
like the multipath configurator assigns the node name attribute to be the
combination of SCSI initiator and target addresses (in linux, host
no/channel no/target id).  This should be different for every path which
would cause each path to be assigned to a different path group.

How is the resultant path grouping any different than if you used the
failover
path grouping policy instead?
