Several diagnostic tools exist at the Mnemonic Debugger (MD) level. In this section,
we discuss how to run the Self Test diagnostics and how to interpret the LED error
codes. We also explain the MD level LED status codes and briefly discuss TSC
diagnostics. We document other MD diagnostic tools in the following manuals:

Self Test Diagnostics Overview
Self Test diagnostics consist of Test, Extended Test, and Continuous Test. The Self Test
code resides in the Boot ROM and in a file named self_test in the /SAU directory. We
refer to the part of Self lest that resides in the self_test file as Loadable Tests.

When executing utilities such as calendar, invol, and salvol,
you must specify the device type, along with the controller
number and unit number. For example, if you intend to run
the calendar program, a "device found" message appears on
the screen. When you are prompted to enter the device type
(w,s,f, or other), you must include the controller and unit num-
bers specified in the "device found" message along with the
device type, such as w6:0 (Winchester disk controller 6, unit 0).
