Verify The Infiniband Fabric - Oracle Exalogic Elastic Cloud Owner's Manual

# listlinkup
If the link for a connector is reported as not present, the link at either end of the cable
is down. If a port is down, use the enableswitchport 0 portnumber command
to bring the port up. Alternatively, use the ibdevreset command to reset the switch
chip.
See the Sun Network QDR InfiniBand Gateway Switch Administration Guide, "Enable a
Switch Chip Port" and "Reset the Switch Chip".
After making sure that the link is up, you can verify the InfiniBand fabric.
The following is an output example of the listlinkup command:
# listlinkup
