Troubleshooting 3-7
Example 3–1 shows a memory error report in the middle of power-up. In this
case memory failed self-test and the report shows that the most likely FRU is
memory 1 in QBB1.
The SROM/XSROM diagnostic reports errors using error and warning formats:
*** Designates a diagnostic error format. Depending on the type of error
and the configuration, the machine will most likely power up. At a
minimum the resource is dropped from the system.
###
Designates a diagnostic warning format. The machine will power up
and the resource will most likely be available.
The SCM reports the following:
~E~
Designates an error detected by the scm/psm/hpm/pbm. Depending
upon the type of error and system configuration, the machine will most
likely power up but the resource is dropped. If you see ***, you'll also
see ~E~.
~W~
Designates a warning and is much like ~E~ except it is not as severe.
The machine will most likely power up but the resource is questionable.
An example would be the failure of a redundant power supply in the
PCI; the machine powers up and the PCI resources are available.
~I~
Designates an information message about power-up progress or
configuration.
Table 3–3 lists the messages sent to the OCP’s fluorescent display during
power-up and when a number of system events occur. It is another source of
information that may be useful when troubleshooting or configuring the
machine.
