Execute the diagxbu command to diagnose the crossbar cables.
Diagnosis is performed when the system board of the chassis connected with the
crossbar cables is not incorporated into the physical partition, or when the
physical partition into which the chassis is incorporated is powered off.
The example below specifies the following:
00: BB-ID of the chassis to start the diagnosis
01: BB-ID of the destination where the chassis to start the diagnosis is connected
(You can specify one or more of these.)
To specify multiple connection destination BB-IDs, enter a command like
"diagxbu -y -b 00 -t 01 -t 02".
XSCF> diagxbu -y -b 00 -t 01
