Service manual

Self-test is invoked and results are written to the console under several
circumstances:
• At power-up
• When the control panel Restart button is pressed
• During a boot
• When the console command INITIALIZE is issued
On a <REFERENCE>(rigel) the first line of the self-test printout is the
progress trace. This line indicates how the <REFERENCE>(XRP) at node
1 is functioning during self-test. If there is no processor in node 1, no trace
appears.
The remainder of the printout is the self-test display. Table 2–1 describes
the tests run during self-test. The callouts in Table 2–1 refer to
Example 2–1.
Table 2–1: Self-Test Components
Test Description
Processors Each processor runs its own self-test resident in its own ROM. A plus sign (+)
on the STF line
1
means the processor passed. Each processor also tests in-
teraction with memory. A plus sign on the ETF line
2
means the test
passed.
Memory Each memory runs its own on-board self-test. A plus sign on the STF line
1
means the memory passed.
<REFERENCE>(XBI_
PLUS)
The <REFERENCE>(XMI)-to-VAXBI adapter is tested by the boot proces-
sor. A plus sign at the right of the XBI line
3
means both the DWMBB/
A and DWMBB/B modules passed.
VAXBI Each VAXBI bus on the system is checked, and each VAXBI node runs
its own self-test. A plus sign in column 0 through F of the XBI line
3
means
the VAXBI node passed.
The self-test printout in Example 2–1 reflects a specific configuration. A
detailed explanation of self-test results is available by typing HELP SELF
at the console prompt, or see the VAX 6000 Series Owner’s Manual.
The tests run during self-test can be individually invoked in RBD mode
using the ROM-based diagnostics monitor program. Here you can examine
each test more closely and determine which test is failing.
Two different ROM revision lines are possible. Example 2–1 shows the
KA64A revision line (see
4
). The KA62B revision line follows:
