Maintenance Mode - HP Series 37 Reference Manual

Operating Instructions
MAINTENANCE MODE
Maintenance Mode allows the System Operator to perform a number of functions. The major functions
which can be performed are the LOAD/START/DUMP and Test commands.
LOAD
and
START
load MPE
from tape or disc respectively, and the DUMP command loads the dump software from the START device.
The TEST command allows the System Operator to run the Power-on Self Tests with failures displayed on
the System Console. The Test Mode also allows a limited looping feature. Tests can be looped with the
count
parameter.
Count
must be an integer between \ and 9999, with I being the default. The looping
feature is disabled when the keyswitch is in the position "\" (NORMAL).
The
LOAD, START,
and
DUMP
commands require a channel and device specification unless the default
device has been set up by the " ,P" and ", C" options. The DUM P command always def a \II ts to the START
device. The", P" option updates the LOAD or START device data in the TOC and initiah~, the LOAD or
ST ART. The TOC is a permanent storage area for system information which includes the default START
and LOAD device numbers. The TOC LOAD or START data can also be updated with the ",C" option
but the LOAD or START is not periormed. Thellid channels are 1, 3, or 4 for main and 9-\3 for the
extender.
RUN
attempts to "run" the system if it arrived in Maintenance Mode via a Halt or Control
B.
The "AR" command allows the System Operator to try another Autorestart if the system has given up (5
tries d approximately 90 seconds each). The other LOAD/STMrr type commands (COO, COL, DIS, NEW,
RELO, TAPE, UPDA, and WAR) use the LOAD or START deivce as stored in the TOe. Table 2-3 lists the
valid Maintenance Mode Commands. For details on the correct syntax of these commands refer to Section
III "COMMAND DESCRIPTIONS".
