Enter RBD mode from console mode. The RBD prompt appears and
indicates you are operating from the boot processor at node 1.

Run RBD 0 and trace the tests. The CPU test runs all 37 tests
successfully.

Run RBD 1, trace it and halt on the first error found. All CPU/memory
interaction RBD tests run and pass.

Run RBD 2, testing the DWMBB at XMI node 5. The value NO_UNIT
on the third line of output indicates that the node value of node 5 is not
correct; no DWMBB was found at this node.
5
Run 3 passes of tests 2 through 4 of RBD 2 on node E with Trace Set.
Note that the T00nn line lists each of the three tests three times, since
the /P=3 called for 3 passes of the tests. And the final parameter in the
summary line is a 3, indicating that 3 passes completed.
