NAME [Toc] [Back]
diag2 - interface for diagnostic logging and interface to processors
DESCRIPTION [Toc] [Back]
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
AUTHOR [Toc] [Back]
diag2 was developed by HP.
