 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
      future failures.

 AUTHOR    [Toc]    [Back]
      diag2 was developed by HP.
