Hi SND,
So do all hosts connecting to same IB switch show the same outputs of “iblinkinfo” and “ibnetdiscover” ?
Answer - yes,maybe in a different order, but the data is the same
As in host-1 isn’t going to link a port to a different host then host-2 would?
Answer - same as above - the data should the same, the order may be different
I dug up some old explanation that I did for the output of iblinkinfo, hopefully this will make it more clear:
Description of each column in the output:
Switch
Switch name:
Switch type and model:
Switch 0x0002c90200430e20 MF0;SUPP-5100:IS5100/L01/U1:
Switch
LID
Port Number
Width
Speed
Logical
state
Physical State
LID of connected device
Physical Port in the connected device
for voltaire chassis - the external port number if external
Name of connected device
Type of connected device
