PowerLinux provides additional RAS features
Examples include:
PCI bus error detection and recovery
–Implemented by EEH (Extended I/O Error Handling) on Power
• In the kernel and device drivers; no userspace tools needed
–Autonomic detection and recovery for most errors
Platform error logging and analysis
–Platforms provides the OS with notifications of failures (hardware failures,
firmware/hypervisor issues, etc.)
–These events are received and logged to servicelog.
–Certain failures also handled
• Predictive CPU failures will cause the failing CPU to be taken offline (a.k.a.
CPU Gard)
• EPOW (Environmental and Power events), such as a switch to UPS power, a
fan failure, or a thermal condition, may shut down the system
• Platform dumps (FSP dumps, PHYP dumps, etc.) may be generated by the
platform for future analysis
