Use the lsnwmiswire command to identifying and resolving a physical mis-cable, as shown in
the following example:
# lsnwmiswire
FR004-CG09-SN011-DR0-HB5-D5 DOWN_MISWIRED ExpNbr: FR004-CG07-SN010-DR0-HB5-D4
ActualNbr: FR004-CG07-SN010-DR0-HB5-D5
FR004-CG09-SN011-DR0-HB4-D5 DOWN_MISWIRED ExpNbr: FR004-CG07-SN010-DR0-HB4-D4
ActualNbr: FR004-CG07-SN010-DR0-HB4-D5
The lsnwmiswire output: The following lsnwmiswire output indicates that two D-Links are
incorrectly cabled:
FR004-CG09-SN011-DR0-HB5-D5 is connected to FR004-CG07-SN010-DR0-HB5-D5
instead of FR004-CG07-SN010-DR0-HB5-D4, as expected.
FR004-CG09-SN011-DR0-HB4-D5 is connected to FR004-CG07-SN010-DR0-HB4-D5
instead of FR004-CG07-SN010-DR0-HB4-D4, as expected.
This instance is typical of two fiber cables that are plugged into the wrong ports at the D-Link
hub. The problem is resolved by swapping the following cables at the specified D-link ports:
The end of the cable plugged into FR004-CG07-SN010-DR0-HB5-D5 is moved to
FR004-CG07-SN010-DR0-HB5-D4 and the end of the cable plugged into
FR004-CG07-SN010-DR0-HB4-D5 is moved to FR004-CG07-SN010-DR0-HB4-D4.
After the mis-cables are corrected, rerun the lsnwmiswire command to check that the links
are no longer reported as DOWN_MISWIRED.

4.3.3 SMS ping test fails over HFI

If the SMS ping test over HFI fails, check the following conditions or try the following fixes:
Is hf0 configured and working properly on the service node?
Are the HFI device drivers installed on the service node?
Is ipforwarding set to 1 on the service node?
Does lsnwloc show the CEC at RUNTIME?
Are the FSPs pingable?
Restart lnmcd on the FSP.
Ensure that CNM and the HFI device driver are up to date on the service node.
