19 ibdiagpath traces a path between two end-points and provides
20 information regarding the nodes and ports traversed along the path. It
21 utilizes device specific health queries for the different devices along
22 the traversed path. The way ibdiagpath operates depends on the
23 addressing mode used on the command line. If directed route adressing
24 is used, the local node is the source node and the route to the
25 destination port is known apriori. On the other hand, if LID route (or
26 by-name) addressing is imployed, then the source and destination ports
27 of a route are specified by their LIDs (or by the names defined in the
28 topology file). In this case, the actual path from the local port to
29 the source port, and from the source port to the destination port, is
30 defined by means of Subnet Management Linear Forwarding Table queries
31 of the switch nodes along those paths. Therefore, the path cannot be
32 predicted as it may change. The tool allows omitting the source node,
33 in which case the local port on the machine running the tool is assumed
34 to be the source. Note: When ibdiagpath queries for the performance
35 counters along the path between the source and destination ports, it
36 always traverses the LID route, even if a directed route is specified.
37 If along the LID route one or more links are not in the ACTIVE state,
38 ibdiagpath reports an error. Checks for path validity from partitions,
39 IPoIB and QoS perspectives are also provided.
