Understanding Service Procedures
If you want to know the link status of a node in the InfiniBand fabric, the ibportstate command can tell you the state, width, and speed of that node.
On the management controller, type:
# ibportstate lid port
where:
lid is the LID of the node.
port is the port of the node.
For example:
# ibportstate 24 8 PortInfo: # Port info: Lid 24 port 8 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 Peer PortInfo: # Port info: Lid 24 DR path slid 25; dlid 65535; 0,8 port 2 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 #
In the output, the Active parameters are the current state of the port.
