Verifying Communications within the Fabric

IMPORTANT

Verifying Communications within the Fabric

You can verify the communications within the fabric by running the clic_probe command, which is described below. You can also use clic_probe to verify the status of specific adapters.

You should also check your /etc/hosts file—when you are using files for host name look up—to ensure that the entries for all of the systems are in the correct format: the official host name, which is the full domain extended host name, and any alias names. For example:

IP_address bently6.corp3.com bently6

IP_address bently4.corp7.com test1

IP_address bently2.corp4.com test3

The clic_probe Command

Run the clic_probe command to send 256-byte packets to verify the link out to and back from a specific destination, optionally using a specific adapter for the verification. The destination can be either a node or a switch (if a switch is part of the fabric).

If you include /opt/clic/bin in your PATH statement, you can run the command as it is shown below. Otherwise, you must include /opt/clic/bin as part of the command name (that is, /opt/clic/bin/clic_probe).

You do not have to be logged in as root to run this command.

The syntax is as follows:

clic_probe node_name [-cadapter_ID]

[-cadapter_ID -rVRID switch_hopcount] [-l-cadapter_ID] [-s-cadapter_ID] [-ppacket_count] [-?]

Note that some of the lines in the above syntax are indented for readability purposes only. When you actually type the command, you do not indent anything.
