10.5.2 Diagnosing the XBU and Crossbar Cable


10.5.2 Diagnosing the XBU and Crossbar Cable
This section describes the procedure for diagnosing the XBU and crossbar cable in a building block configuration.
<‌Description of options>‌
-b: Specify the BB-ID of the released SPARC M12-2S (communication source).

-t: Specify the BB-ID of the released SPARC M12-2S (communication destination).

-p: Specify the PPAR-ID (communication destination).
(1) Communication destination PPAR is running (active addition)
The following execution example diagnoses the XBU and crossbar cable between the SPARC M12-2S of BB#1 and the SPARC M12-2S operating in PPAR#0.
XSCF> diagxbu -y -b 01 -p 0
XBU diagnosis is about to start, Continue?[y|n] :y
Power on sequence started. [7200sec]
0..... 30..... 60..... 90..end

XBU diagnosis started. [7200sec]
0..... 30..... 60..... 90.....120.....150.....180.....210.....240.....|

270.....300.....330.....360.....390.....420...end

completed.
Power off sequence started. [1200sec]
0..... 30..... 60..... 90.....120end

completed.
*Note*
Please confirm the error of XBU by "showlogs error".
In addition, please confirm the degraded of XBU by "showstatus".
(2) Incorporation destination PPAR is stopped (inactive addition)
The following execution example diagnoses the XBU and crossbar cable between the SPARC M12-2S of BB#3 and the SPARC M12-2S of BB#1 and BB#2 contained in PPAR#1, which is the incorporation destination.
XSCF> showpcl -p 1
PPAR-ID LSB PSB Status

00 01-0
01 02-0
XSCF> diagxbu -y -b 03 -t 01 -t 02
XBU diagnosis is about to start, Continue?[y|n] :y
Power on sequence started. [7200sec]
  0..... 30..... 60..... 90.....120end
XBU diagnosis started. [7200sec]
  0..... 30..... 60..... 90.....120end
completed.
Power off sequence started. [1200sec]
  0..... 30..... 60..... 90.....120end
completed.
*Note*
Please confirm the error of XBU by "showlogs error".
In addition, please confirm the degraded of XBU by "showstatus".
The hardware diagnosis that is run during the execution of the replacefru command does not cover the crossbar cable. If you have released the SPARC M12-2S from the building block configuration by using the replacefru command, wait until the replacefru command ends, and then diagnose the crossbar cable by using the diagxbu command.
