Verifying Communications within the Fabric

Chapter 5112

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.
