The system conﬁguration being tested is discussed in Section 6.2. See

Table 6–1.

The BPD line

indicates boot processor designation. When the system

goes through self-test, the processor with the lowest ID number that

passes self-test (STF line is +) becomes the boot processor, unless you

intervene. Using the SET CPU command and its qualiﬁers, you can

change the eligibility of the processors to become the boot processor

(see Section 5.18.2).

The results on the BPD line indicate:

• The boot processor (B)

• Processors eligible to become the boot processor (E)

• Processors ineligible to become the boot processor (D)

This BPD line is printed twice. After the ﬁrst determination of the

boot processor, the processors go through an extended test. Since

it is possible for a processor to pass self-test (at line STF) and fail

the extended test (at ETF), the processors again determine the boot

processor following the extended test.

In Figure 6–5 the processor at node 3 was chosen boot processor. Then

this processor failed the extended test, so the processor at node 4 was

chosen boot processor.

During the extended test (ETF) all processors run additional CPU tests

involving memory. In Figure 6–5, results printed at this ETF line

indicate:

• Two processors passed the extended test (+)

• Two processors failed the extended test (–)

For vector processors, either an "E" or a "D" appears on both BPD lines. An "E" indicates

that the vector processor is enabled for use with system software; a "D" indicates that the

vector processor is disabled.
