[ewg] ibportstate of infiniband-diag 1.6.2 and after

[Chen, Mei-Jen]

Hi Ira,

The problem seems to be related on what HCA and particular firmware version.
I redo tests on Mellanox MCX353A-QCBT and Intel/Qlogic QLE7340.
So far
Intel/Qlogic QLE7340, ibportstate 1.6.1 OK, ibportstate 1.6.2 OK
Mellanox MCX353A-QCBT, firmware 2.10.700 , ibportstate 1.6.1 OK, ibportstate 1.6.2 NG, ibportstate 1.6.4 NG
Mellanox MCX353A-QCBT, firmware 2.30.8000(latest) , ibportstate 1.6.1 NG, ibportstate 1.6.2 NG, ibportstate 1.6.4 NG

Attached please see  "mellanox_qdr.txt" and "qlogic_qdr.txt" for the output of the command.

Thanks,
Mei

There are not that many differences in ibportstate between 1.6.1 and 1.6.2.

Do you have any output from the command which fails?  What HCA's are these?

Could you run with the "-d" and "-v" options for both tools and send the output.

Thanks,
Ira

Hi,

I have been using utility "ibportstate" from "infiniband-diag 1.6.1" package to force lower link up speed.
It's working properly until I upgrade to newer version of "infiniband-diag 1.6.2" or ""infiniband-diag 1.6.4".  Example of  "ibportstate 2 1 speed 1"  does not seem to have any effect.  Does anyone know the potential causes?

Thanks,
Mei
