Start Diagnostic Test
Diagnostic tests interrupt normal adapter operations. At the completion of the
testing, the adapter’s state before the tests are restored. Note the following:
Run these tests when no other activities are required of the adapter.
Tests read and write to sensitive areas on the adapter.
Disruption of some diagnostic tests may require a complete update of the
adapter's critical memory areas.
The loopback test is external to the adapter. If the adapter port is in loop mode,
you can run the loopback test with a loopback connector. If the adapter port is in
point-to-point mode and attached to a switch, an echo test is run instead (no
loopback connector is used). In addition, some driver versions do not require a
loopback connector.
The test evaluates the ports (transmit and receive transceivers) on the adapter.
More specifically, the loopback test transmits and receives (loopback) the
specified data and checks for the frame CRC, disparity, and length errors.
To prepare for a loopback test:
1. In interactive mode, type the number for the Configure HBA Settings
option, and then press
ENTER
.
2. From the Connections Options menu (interactive mode) or the -n
command (non-interactive mode), do one of the following:
NOTE:
The diagnostic loopback test is not available for the QLE8042 adapter.
NOTE:
Although SANsurfer FC/CNA HBA CLI protects against normal operation
interruption and testing disruption, it is your responsibility to ensure that the
diagnostics are run without causing interruptions to other processes and
disruptions to the actual testing process.
NOTE:
Under Solaris, this feature is disabled if you are using the driver from the OS
installation CDs (QLC driver).
