Running Diagnostics

• -B speciﬁes that you want the size (in bytes) of the trace buffer to be

trace_buffer_size

. The buffer is dynamically allocated when

tracing is enabled. Also, the buffer is circular, which means that

when the end of the buffer is reached, the data wraps around to the

beginning of the buffer (and overwrites any previous data). If you do

not specify this parameter, a default buffer is created with a size of

64k bytes.

• -F speciﬁes

trace_file_size

as the maximum size of the trace

output ﬁle. For the -D TCP_IP parameter, the ﬁle is

/var/adm/clic_ip_drv.trc. For the -C TCP_IP parameter, the ﬁles

are /var/adm/clic_ip_drv.trc0 (and if needed,

/var/adm/clic_ip_drv.trc1).

• -d dumps the memory of the adapter identiﬁed by

adapter_ID

to the

dump ﬁle

filename

. If you do not specify

filename

, the default ﬁle is

/var/adm/clic_fw.dump

, where

is the adapter instance number.

• -? displays the online help for clic_diag.

If you do not specify any of the above parameters, the online help for

clic_diag is displayed.

Example of clic_diag

An example of the clic_diag command is shown below.

If the local node is bently6, and you want to conﬁrm that all of the

adapters on bently6 are communicating with the target adapters on

bently8, issue this command:

$ clic_diag -r bently8

The generated output could look like this:

CLIC_PROBE: 256 byte packets

Source adapter id: bently6.corp4.com:clic0

Target adapter id: bently8.corp2.com:clic1

256 bytes: seq_num = 0. Packet Acknowledged.

256 bytes: seq_num = 1. Packet Acknowledged.

256 bytes: seq_num = 2. Packet Acknowledged.

256 bytes: seq_num = 3. Packet Acknowledged.

256 bytes: seq_num = 4. Packet Acknowledged.

--------- CLIC_PROBE Statistics --------

5 packets transmitted, 5 packets received, 0% packet loss.
