That shouldn't be the case. OpenSM should do this on any addition/subtraction of a link depending on the sweep_on_trap option. > My vendor has bad habit of asking me to add ib link here and there to > nullify bottleneck identified and, well, while all new paths are up, I can > find no way of rebalancing paths, so they stay unused. > > I'm running OFED-1.3.2-20090119-0501, so all ideas for this version or a > newer one are welcome. Have you tried issuing SIGHUP ? As Ira wrote, when opensm receives a HUP signal, it should start a new heavy sweep as if a trap was received or a topology change was found. As Al wrote, the other alternative is if you are using the console to resweep heavy. Also, a newer OpenSM might help (not sure). There has been discussion of a race in this area but it's unclear whether that's what you are experiencing. -- Hal > Regards, > > kovlensky > > > ---------------------------------------------------------------------- > Szybkie i niedrogie...
