Hi,

 

Thanks for the help, however, unfortunately this didn't help.

 

Without firing command:

 

CA PortInfo:

# Port info: Lid 144 port 1

LinkState:.......................Active

PhysLinkState:...................LinkUp

Lid:.............................144

SMLid:...........................442

LMC:.............................0

LinkWidthSupported:..............1X or 4X

LinkWidthEnabled:................1X or 4X

LinkWidthActive:.................4X

LinkSpeedSupported:..............2.5 Gbps or 5.0 Gbps or 10.0 Gbps

LinkSpeedEnabled:................2.5 Gbps or 5.0 Gbps or 10.0 Gbps

LinkSpeedActive:.................10.0 Gbps

LinkSpeedExtSupported:...........14.0625 Gbps

LinkSpeedExtEnabled:.............14.0625 Gbps

LinkSpeedExtActive:..............14.0625 Gbps

# Extended Port info: Lid 144 port 1

StateChangeEnable:...............0x00

LinkSpeedSupported:..............0x01

LinkSpeedEnabled:................0x01

LinkSpeedActive:.................0x00

 

 

After firing the above mentioned commands, i.e.

ibportstate 144 1 fdr10 0 espeed 30

ibportstate 144 1 reset

 

We get below output

 

CA PortInfo:

# Port info: Lid 144 port 1

LinkState:.......................Active

PhysLinkState:...................LinkUp

Lid:.............................144

SMLid:...........................442

LMC:.............................0

LinkWidthSupported:..............1X or 4X

LinkWidthEnabled:................1X or 4X

LinkWidthActive:.................4X

LinkSpeedSupported:..............2.5 Gbps or 5.0 Gbps or 10.0 Gbps

LinkSpeedEnabled:................2.5 Gbps or 5.0 Gbps or 10.0 Gbps

LinkSpeedActive:.................10.0 Gbps

LinkSpeedExtSupported:...........14.0625 Gbps

LinkSpeedExtEnabled:.............14.0625 Gbps

LinkSpeedExtActive:..............14.0625 Gbps

# Extended Port info: Lid 144 port 1

StateChangeEnable:...............0x00

LinkSpeedSupported:..............0x01

LinkSpeedEnabled:................0x00

LinkSpeedActive:.................0x00

 

Can you please help ?
