+When the routing protocol is torus\-2QoS, the following two files are dumped

+
+dump2psl.pl dumps a psl file based on some opensm output files. A psl file
+contains paths (including SLs) and is needed for subsequent credit loop
+checking (via ibdmchk). This conversion is needed when ibutils is not
+installed and credit loop checking is done on a different machine or later.
+Credit loop checking is especially valuable for the QoS based routing
+algorithms (e.g. torus-2QoS, lash, etc.).
+
+ibdiagnet -vlr dumps the psl (and slvl) files needed for ibdmchk -M -a -s
+(which is the credit loop check).
+
+Dumping of path records is accomplished by the PathRecord dumping plugin to the
+OpenSM. When the environment variable DUMP_FULL_PATH_RECORDS is set to 1,
+the full set of SA path records is dumped to opensm-path-records.dump in
+the dump_files_dir directory (default is /var/log).
+
+When the routing protocol is torus-2QoS, the following two files are dumped
+by the PathRecord dumping plugin: opensm-peer-paths.dump and
+opensm-sw2sw-path-records.dump. The peer paths dump file contains the CAs
+and their neighbor switch and includes the link MTU and RATE. The switch to
+switch file contains for each source switch a table of destination switches
+and the SL, RATE, and MTU to be used for MPI traffic.
+
+Note that since the PathRecord dump uses port GUIDs and the ibdmchk psl
+file uses node GUIDs, the fabric .lst file is also required as input
+(see SYNOPSIS).
