I assumed OpenSM was resetting the link. Are you saying I need to run ibportstate reset in addition to running a modified opensm?

I installed the latest version, and it indeed has width and speed. However, it doesn't seem to have any effect: [dki...@f28]~% sudo /usr/sbin/ibportstate 232 1 query PortInfo: # Port info: Lid 232 port 1 LinkState:.......................Active PhysLinkState:...................LinkUp 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 [dki...@f28]~% sudo /usr/sbin/ibportstate 232 1 speed 1 Initial PortInfo: # Port info: Lid 232 port 1 LinkSpeedEnabled:................2.5 Gbps or 5.0 Gbps or 10.0 Gbps After PortInfo set: # Port info: Lid 232 port 1 LinkSpeedEnabled:................2.5 Gbps [dki...@f28]~% sudo /usr/sbin/ibportstate 232 1 query PortInfo: # Port info: Lid 232 port 1 LinkState:.......................Active PhysLinkState:...................LinkUp 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 LinkSpeedActive:.................10.0 Gbps [dki...@f28]~% sudo /usr/sbin/ibportstate 232 1 reset ibportstate: iberror: failed: smp query nodeinfo: Node type not switch Thanks, Dries
