System Self-Test
2-13
4
The BPD line indicates boot processor designation. When the system
completes on-board self-test, the processor with the lowest LSB ID
number that passes self-test and is eligible is selected as boot proces-
sor. This process occurs again after ST2 and ST3 when the boot proc-
essor designation is reported on the second and third BPD lines.
5
During the second round of tests (ST2), all processors run CPU/MEM
tests. On line ST2, results are reported for each processor and mem-
ory; a plus sign (+) indicates that ST2 testing passed and a minus sign
(−) that ST2 testing failed. The boot processor is again reported on the
BPD line.
6
During the third round of tests (ST3), all processors run multiprocessor
tests. Results are reported on line ST3, and the boot processor desig-
nation is again reported on the third and final BPD line.
7
A minus sign (−) at the right of the C0 XMI line means that the
DWLMA adapter on I/O channel 0 failed self-test. Self-test results for
adapters on this I/O channel will not be reported.
8
A plus sign (+) at the right of the C1 XMI line indicates that the
DWLMA adapter on I/O channel 1 passed self-test. However, the
adapter at XMI node 3 failed its own self-test. I/O channels C2 (
9
)
and C3 (
10
) are not used in this configuration.
11
The last line of the self-test display shows the console firmware and
SROM version numbers and the system serial number.
