Mapper; Iotest - HP Model 744 - VME Workstation Installation And Service Manual

Off–Line Diagnostics
The Off–Line Diagnostic Environment (ODE) is used to test to the I/O card level in the
computer system. IOTEST and MAPPER are modules of the ODE that check the
functionality of the I/O modules in the computer system. ODE is run from the Initial
System Loader (ISL) on the system console. Please refer to your system's Owner's Guide
for for more information on running ISL.

MAPPER

ISL>ODE
ODE>mapper
MAPPER>run
The MAPPER utility provides the following hardware information
Path #
Type ID (Architecture Module)
Hardware Version
Hardware and Firmware Versions
SCSI bus address of the host adapter
Names and addresses of devices on the SCSI bus
MAPPER automatically resets the SCSI bus.

IOTEST

ISL>ODE
ODE>iotest
IOTEST>run
The IOTEST's strategy is to systematically check the basic functionality of the I/O
modules in the system. This is accomplished by either making a PDC_IODC call to invoke
selftest, or by running a test within the diagnostic. IOTEST doesn't test the functionality
of devices.
IOTEST is currently divided into 23 sections. Each section performs basic tests on a
particular module.
For the HP SCSI adapter, Section 006 tests the basic functionality of the the interface chip
from the NCR controller chip to the HP (GSC+) backplane. First, there is a register test
