3. Execute the diagxbu command to diagnose the crossbar cables.
Diagnosisis performed when the system board of the chassis connected with the
crossbar cables is not incorporated into the physical partition, or when the
physicalpartition into which the chassis is incorporated is powered off.
Theexa mple below specifies the following:
00:BB-ID ofthe chassist o start the diagnosis
01:BB-ID o ft he destination where the chassis to start the diagnosis is connected
(You can specify one or more of these.)
Tospecif y multiple connection destination BB-IDs, enter a command like
"diagxbu -y -b 00 -t 01 -t 02".
4. Executethe showlogs command to confirm that the system is operating
normally.
For details, see "3.3.5 Checking log information."
5. Switchthe mode switches of the master chassis and those chassis whose
XSCFsare in the standby state to Locked mode.
-Fora building block configuration (without crossbar box)
Switchthe mode switches of BB-ID#00 and #01 to Locked mode.
-Fora building block configuration (with crossbar box)
Switchthe mode switches of BB-ID#80 and #81 to Locked mode.
6. Executethe showstatus command to confirm that there is no problem with
thecrossbar units after the completion of maintenance.
7. Executethe showhardconf command to check the hardware configuration
andthe status of each component.
8. Start thesystem.
For details, see "6.4.1 Starting the system with an XSCF command"or"6.4.2
Starting the system from the operation panel."
