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.
IMPORTANT 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 [-c adapter_ID ]
[-c
adapter_ID -r VRID switch_hopcount ]
[-l -c
adapter_ID ] [-s -c adapter_ID ]
[-p
packet_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.
