PCI Error Handling Product Note What is PCI Error Handling? The PCI Error Handling feature allows an HP-UX system to avoid a Machine Check Abort (MCA) or a High Priority Machine Check (HPMC), if a PCI error occurs (for example, a parity error). If a PCI error occurs on a bus without the PCI Error Handling feature installed, an MCA or an HPMC will occur, then the system will crash.
