System Self-Test 8-5

The NODE # line lists the (hexadecimal) node numbers on the LSB

and XMI buses. Node numbers and slot numbers are identical. Nodes 0

through 3 reflect the right-to-left position of the LSB slots as viewed from

the front of the cabinet. Nodes 4 through 8 reflect the right-to-left position

of the LSB slots as viewed from the rear of the cabinet. XMI entries use

nodes 1 through E.

The TYP line indicates the type of module at each LSB node:

• An adapter: the I/O port module (A)

• A memory module (M)

• A processor (P)

A period (.) indicates that the slot is not populated or that the module is

not reporting.

The ST1–ST3 lines show the results of the testing. This information

is taken from the self-test bit in the LCNR register of each module. The en-

tries are:

• + (pass)

• − (fail)

• o (does not apply). In this example, the I/O port module has "o" be-

cause there is no module-resident self-test.

The BPD line indicates boot processor designation. The results on

this line indicate:

• The boot processor (B)

• Processors eligible to become the boot processor (E)

• Processors ineligible to become the boot processor (D)

The BPD line is printed three times. After the first determination of the

boot processor, the processors go through two more rounds of testing.

Since it is possible for a processor to pass self-test at line ST1 and fail ST2

or ST3 testing, the processors again determine the boot processor following

each round of tests.

The I/O channel lines C0 through C3 indicate the I/O channel that con-

nects the XMI I/O bus to the system bus and indicates self-test results for

the DWLMA and all XMI adapters. In this example, self-test passed on

XMI nodes 1, 2, 3, and 8.
