Finds 1x (or wider) links in the InfiniBand fabric.
ibcheckwidth [-h][-N][-v][topology|-C ca_name][-P ca_port][-t timeout]
topology is the topology file.
ca_name is the channel adapter name.
ca_port is the channel adapter port.
timeout is the timeout in milliseconds.
This InfiniBand command is a script that uses the topology file created by the ibnetdiscover command. The script scans the InfiniBand fabric to validate Active link widths and report those which are 1x (or wider) links.
The following table describes the options to the ibcheckwidth command and their purposes:
The following example shows how to check the 1x (or wider) links for all ports with the ibcheckwidth command.
# ibcheckwidth -v # Checking Switch: nodeguid 0x0021283a8620b0f0 Node check lid 25: OK Port check lid 25 port 36: OK Port check lid 25 port 35: OK Port check lid 25 port 34: OK . . . Port check lid 24 port 30: OK Port check lid 24 port 29: OK ## Summary: 6 nodes checked, 0 bad nodes found ## 142 ports checked, 0 ports with 1x width in error found #
