HP StorageWorks 16-EL - SAN Switch Release Note page 15

The source route is expressed as a sequence of switches, a sequence of output
ports (or areas), or a combination thereof. The next hop in the source route is
described by either the output port (or area) to be used to reach the hop or the
domain ID of the next hop.
The source route can specify a partial route from source to destination—in which
case the remaining hops are chosen as the path from the input port (or area) on the
first hop not listed in the source route to the destination—a full route, or an
arbitrary route across the fabric. The maximum hop count is enforced.
If the source route does not specify all the switches along a section of the path, a
further option allows the user to specify a strict path versus a loose path. A strict
source route requires that only the specified switches be reported in the path
description. If two switches are specified back-to-back in the source route
descriptor but are not directly connected, the switches in between them are
ignored. For a loose source route, the switches in between are reported. The
concepts of strict and loose route apply to the portions of the path described by
domains, not to the part described by output ports or areas.
Operands
The following operands are allowed:
SAN Switch 2/16 Fabric OS 3.1.2 Release Notes
domain The ID of the destination domain.
source port The port (or area) whose path to the destination domain is
sought. The embedded port (-1) is used by default. For a
switch with blades, the destination is specified as the area;
otherwise, as the port. If the source port is given as -1 with
no additional arguments, then basic statistics are displayed
for the route.
destination A port on the destination switch. The pathInfo command
port returns the state of the port (or area). The embedded port (-1)
is used by default or if the user specifies a destination port
that is not active. For a switch with blades, the destination is
specified as the area; otherwise, as the port.
Show reverse path in addition to the forward path in the
–r
output display.
