[openib-general] Setting HCA LinkWidth

[Amit H Kumar]

Hi OpenIB,

I am not sure if this question belongs to this list or not. But if anyone
can give me some lead it will be very helpful.

One of the HCA card in our cluster is running at LinkWidth 1x: as opposed
to 4x on all other nodes.
I have been trying to set it to 4x using the iba_portconfig tool but
nothing seems to work.

Can anyone tell me what is the general approach in doing so.

Thank you for any feedback,
-AK
