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 sub-

system. 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

diag0 was developed by HP.
