NAME
diag0 — diagnostic interface to HP-PB I/O subsystem
DESCRIPTION
diag0
is a diagnostic pseudo-driver, which provides HP support tools
with access to the HP-PB I/O subsystem. This driver is
used by hardware monitors and tools within the Support Tools
Manager (STM), to interact with peripherals connected to
the system via HP-PB. The I/O drivers also send diagnostic events to
diag0
for diagnostic logging by the Support Tools Manager.
Without
diag0,
information that could help prevent a
peripheral failure will be lost. In addition, if
a failure occurs, HP will not have the tools or data to
diagnose the cause of the problem in a timely manner. This
may cause increased downtime and possible future failures.
AUTHOR
