Fbus_Diag - DEC 4000 AXP Service Manual

3.1.9 fbus_diag

The command is used to start execution of a diagnostic test script
fbus_diag
onboard a specific Futurebus+ device.
The fbus_diag comand uses the Futurebus+ standard test CSR interface to
initiate commands on specific Futurebus+ devices, waits for tests to complete, and
then reports the results to the console. If an error is reported by the Futurebus+
node, the diagnostic issues a dump buffer command to gain any available
extended information that will also be reported to the console.
Refer to documentation for the specific Futurebus+ option for the recommended
test procedures and form of the
diagnostics. For more information, consult the Futurebus+ Handbook.
Test categories that require a buffer pointer in the argument CSR will have a
default buffer provided by this diagnostic if the user does not specify a buffer
address.
Process options and command line arguments are used to specify the specific
test or test script to be executed as well as the target Futurebus+ node for this
command.
Synopsis:
fbus_diag [-rb] [-p pass_count] [-st test_number] [-cat test_group node [test_arg]
Arguments:
node Specifies the device name of the Futurebus+ device to execute the test.
Use the command
names.
[test_arg] Specifies an argument to be passed to the Futurebus+ node in the test
argument CSR. If this parameter is not specified and the category is
either extended or system, the routine allocates a buffer and passes the
buffer address through the test argument CSR.
Options:
[-rb] Randomly allocates from memzone on each pass with a block size of
4096.
[-p] (pass_count) Specifies the number of times to run the test. If 0, the
test runs continuously. This overrides the value of the pass_count
environment variable. In the absence of this option, pass_count is used.
The default for pass_count is 1.
[-st] (test_number) Specifies the test number to be run. The default is 0,
which runs the default tests in the category.
