Echo test

Use the BCU and HCM to initiate an echo test between the adapter port and a Fibre Channel end

point. This sends an ECHO command and response sequence between the adapter port and target

port to verify connection with the target.

Performing an echo test through BCU

Use the fcdiag --fcecho BCU command to initiate an echo test between the adapter and remote

port.

fcdiag –-fcecho <port_id> <rpwwn> [-l <lpwwn>]

where:

port_id ID of the port that you want to test. This could be the PWWN, port hardware

path, or user-specified port name. This could also be the

adapter-index/port-index. For example, to specify adapter 1, port 1 you would

use 1/1 as the port identification.

rpwwn Remote port WWN to which the echo command is being sent.

lpwwn Logical port WWN. 0 indicates the base port.

Performing an echo test through HCM

Use the Echo Test feature as follows to initiate an echo test between the adapter port and a Fibre

Channel end point.

1. Launch the HCM.

2. Select Configure > Diagnostics to display the Diagnostics dialog box.

3. Click the FC Protocol Tests tab.

4. Select Echo Test.

5. Select the adapter port and target port for the test.

6. Enter a test cycle if applicable.
