testboard -h
Options/Parameters
-h displays help for this command.
board_name is sb0-sb5 for CPU/Memory boards.
Description
Tests the CPU/Memory board name specified on the command line. This board
cannot be used in an active domain and must be powered on. If running from a
domain, the board must be assigned to the domain. The Repeater boards required to
run the domain must also be powered on.
The testboard command runs tests at the levels set in the domain. Testing a
CPU/Memory board is most accurately done when it is part of a domain. It is best if
the CPU/Memory board can be tested by POST. However, if that is not possible,
testing in the domain is the next best test.
Caution – When testing a CPU/Memory board that is assigned to a domain and the
domain is active, there is a very slight possibility that problems can occur with the
active domain. To prevent this from being a problem, unassign the board from the
domain and test the board from the platform shell.
