Hi,
I have question regarding ibdiagnet and credit loop checking. In debug.tcl
there seems to be two different credit checks:
# report credit loops
ibdmCalcMinHopTables $fabric
set roots [ibdmFindRootNodesByMinHop $fabric]
if {[llength $roots]} {
inform "-I-reporting:found.roots" $roots
ibdmReportNonUpDownCa2CaPaths $fabric $roots
} else {
ibdmAnalyzeLoops $fabric
}
What is the difference between these two checks? From a brief inspection
of the relevant code I would guess that "ibdmReportNonUpDownCa2CaPaths"
checks the routing table for volations of the UpDown rule, while
"ibdmAnalyzeLoops" checks the routing table for cyclic dependencies. Is
this correct?
Best regards,
Sven-Arne
