HPFLDIAG Capabilities
The HP 27115A
HP-FL
diagnostic software,
HPFLDIAG,
is part of the Online
Diagnostic Subsystem and will detect
HP-FL
hardware faults. Use of the
diagnostic is thoroughly described in the SPU and Device I/O Diagnostics
Manual (09740-90020). The information below is a summary of its operation.
The use of
HPFLDIAG
to troubleshoot a link failure may not be possible if the
remote device is the boot disk, unless some other mechanism for loading
HPFLDIAG
is available.
HPFLDIAG
does the following things:
• Identifies the
PCA
and the remote device.
• Reports the status of the
PCA.
• Resets the
PCA.
• Tests the majority of circuits on the
PCA.
• Performs the loopback tests
- to exercise the
PCA
connection to the
CIO
bus,
- to exercise the
PCA,
- to check the
PCA
optical ports (using a loopback cable),
- to check the connection to the remote peripheral.
• Troubleshoots the
link
and identify probable faulty hardware.
Running HPFLDIAG
HPFLDIAG
is accessed via the Online Diagnostic Subsystem,
SYSDIAG.
The
user's interface to
SYSDIAG
is a command interpreter program, Diagnostic User
Interface
(DUI).
To run
HPFLDIAG,
you must execute
SYSDIAG
and enter an
HPFLDIAG
run string at the
DUI
prompt (DUI
».
Note
On
HP MPF/XL
systems, the
DUI
is normally called by entering "SYSDIAG".
The
HPFLDIAG
run string must include a physical device
(PDEV)
specifier of the
PCA
under test (consult your system manager). Also in the run string, you may
specify the diagnostic "sections" to be executed. These "sections" are briefly
described later. The example on the next page illustrates how to start
HPFLDIAG.
Note that user input is bold.
An online description of
HPFLDIAG
is available if you type "help hpfldiag" at the
DUI > prompt. If you type "help hpfldiag section", a description of the
HPFLDIAG
sections is displayed.
Once running,
HPFLDIAG
provides an introductory header, then prompts you for
a target device (0 through 7). If a cluster of devices is connected, the target
device need not be the one attached directly to the
HP-FL
cable.
