Finds 1x links in the InfiniBand fabric.
ibcheckwidth [-h][-N][-v][topology|-C ca_name][-P ca_port][-t timeout]
where:
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 the links that are 1x links.
The following table describes the options to the ibcheckwidth command and their purposes:
|
The following example shows how to check the 1x links for all ports with the ibcheckwidth command.
Note - The output for your InfiniBand fabric will differ from that in the example.
