6.3.1 Diagnosing the Crossbar Unit and Crossbar Cables
This section shows an example of the command for diagnosing the crossbar unit mounted in the physical partition chassis in a system with a building block configuration. The command also diagnoses the crossbar cables in the chassis and their connection status.
The following example shows the diagnosis of the crossbar cable between PPAR-ID 0 and BB-ID 1 and the crossbar unit.
The meanings of the specified options are as follows.
-b bb_id

Specify the BB-ID of the chassis of the SPARC M12-2S or the SPARC M10-4S to start the diagnosis.
You can specify bb_id with an integer from 0 to 3 for the SPARC M12-2S or SPARC M10-4S (without the crossbar box) or from 0 to 15 for the SPARC M12-2S or SPARC M10-4S (with a crossbar box). This option can be specified with -t or -p.

-p ppar_id

Specify the PPAR-ID of the physical partition on which the SPARC M12-2S or SPARC M10-4S chassis that is the communication destination is operating.
You can specify ppar_id with an integer from 0 to 15 depending on the system configuration.

*Note*
Please confirm the error of XBU by "showlogs error".
In addition, please confirm the degraded of XBU by "showstatus".
Even if you perform maintenance on the chassis of the physical partition (including the CPU memory unit) with the replacefru command, the diagxbu command is not executed. After physical partition maintenance work with the crossbar unit and crossbar cables removed, use the diagxbu command to diagnose the condition of the crossbar unit and crossbar cables and the crossbar cable connection status.
