Troubleshooting 3-29
Test &pc1 5 is an example of using a test number to run a single test. The
SCM command-line interface does not accept a list of tests using this
format; however, it does accept masks and continuous or multiple passes.
test &pc1 80 10 0 is an example of the format used to pass a mask. “80”
indicates to the SCM that a diagnostic mask will follow. In this case, 10 is
the first quadword of the mask and 0 is the second. The 5
th
bit is set in the
first quadword, so test 5 is executed on CPU1. The command in
is
equivalent to the command in
.
test &pc1 80 ff 0 is an example of the format used to request the execution
of several tests in sequence. In this case, the first quadword mask has bits
0 through 7 set so those tests are executed.
test &pc1 80 ffe 0 20 is an example of a format used to request 20 passes
of tests 0 through b – all the SROM test.
Test &pc0 80 ff0000 0 is an example of using the mask format to run
XSROM tests. In this case tests 10 through 1b are executed.
A few other restrictions apply to running diagnostics as follows:
• XSROM test ^x10->^x33 (the local QBB tests) can be executed before but
not after either test ^x34 ( Soft QBB ID Config) or test ^x37 (Remote Soft
QBB ID config).
• Test ^x34 (Local Soft QBB ID Config) MUST be run before Test ^x37
(Remote Soft QBB ID config), and Test ^x52 (Memory/DIRectory config) can
be run and also before Console Unload (Test ^x58) can be performed.
• Tests ^x1b (Local IOP config) and ^x38 (remote IOP config), if no local
CPUs are present in a remote QBB, MUST be run to configure the I/O
subsystem and determine the location of the STD I/O module(s). Test ^x58
(Console Unload) requires STD I/O information to determine the location of
the STD I/O flash ROM where the SRM console image resides.
• Once the console is loaded and running, no SROM/XSROM testing can be
done. Since there is no communication between PSM and SROM/XSROM,
the user can NOT do SCM monitor examines, deposits, or test. When the
SRM console is running, SRM level examines, deposits, and test are
available.
