Hi Gilles, using your command: [openpower:88536] mca: base: components_register: registering framework pml components [openpower:88536] mca: base: components_register: found loaded component pami [openpower:88536] mca: base: components_register: component pami register function successful [openpower:88536] mca: base: components_open: opening pml components [openpower:88536] mca: base: components_open: found loaded component pami [openpower:88536] mca: base: components_open: component pami open function successful [openpower:88536] select: initializing pml component pami findActiveDevices Error We found no active IB device ports [openpower:88536] select: init returned failure for component pami [openpower:88536] PML pami cannot be selected -------------------------------------------------------------------------- No components were able to be opened in the pml framework.
This typically means that either no components of this type were installed, or none of the installed componnets can be loaded. Sometimes this means that shared libraries required by these components are unable to be found/loaded.
