System Troubleshooting and Diagnostics

5.2 Product Fault Management and Symptom-Directed Diagnosis

$ VAXSIM/FAULT SET PHONE 1-800-DIGITAL

Finally, the VAXSIMPLUS/MERGE command is useful in examining how a

device is functioning in a cluster. The merge command collects the messages

that are being sent to the other CPUs in the cluster.

5.2.10 Repair Data for Returning FRUs

When sending back an FRU for repair, include as much of the error log

information as possible. If one or more error ﬂags are set in a particular

entry, record the mnemonic(s) of the register(s), the hex data, and error

ﬂag translation(s) on the repair tag. If an error address is valid, include

the mnemonic, hex data, and translation on the repair tag as well. For

memory and cache errors, include the syndrome and corrected-bit/bit-in-error

information, along with the register mnemonic and hex data. Other registers

which should be recorded for any entry type are SYSTAT, MEMCON and

FOOTPRINT.

5.3 Power-On Self-Test (POST) and ROM-Based Diagnostic

(RBD) Failures

If any of the tests fail, the test code displays on the console LED and, if

speciﬁed in the ﬁrmware script, a diagnostic console printout displays in the

format shown in Example 5–11.

Several lines are printed in the error display. The ﬁrst line has eight column

headings:

Test identiﬁes the diagnostic test, test ?40 in Example 5–11. Using

Table 5–4, you can use the test number to point to possible problems in

ﬁeld replaceable units (FRUs).
