NAME
diag2 — interface for diagnostic logging and interface to processors
DESCRIPTION
diag2
is used by hardware monitors and tools within the Support Tools
Manager (STM), to interact with processor hardware via Processor
Dependent Code (PDC). Without
diag2,
support tools for processors
will not be able to operate.
diag2
is also the key component for the following support features:
I/O error logging
Low priority machine check (LPMC) logging
Memory error logging
Pro-active memory page deallocation.
Without the above, information that could help prevent a
system or 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

was developed by HP.
