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.
