IBM Power 595 Technical Overview and Introduction
POWER6 memory protection key feature to increase the reliability of large, complex
applications running under the AIX V5.3 or AIX 6 releases.
Concurrent AIX kernel update
These updates allow installation of some kernel patches without rebooting the system.
This can reduce the number of unplanned outages required to maintain a secure, reliable
system.
Dynamic tracing
This facility can simplify debugging of complex system or application code. Using a new
tracing command,
probevue , developers or system administrators can dynamically insert
trace breakpoints in existing code without having to recompile which allows them to more
easily troubleshoot application and system problems.
Enhanced software first failure data capture (FFDC)
AIX V5.3 introduced FFDC technology to gather diagnostic information about an error at
the time the problem occurs. Like hardware-generated FFDC data, this allows AIX to
quickly and efficiently diagnose, isolate, and in many cases, recover from problems and
reducing the need to recreate the problem (and impact performance and availability)
simply to generate diagnostic information. AIX 6 extends the FFDC capabilities,
introducing more instrumentation to provide real time diagnostic information.
4.3 Serviceability
The IBM POWER6 Serviceability strategy evolves from, and improves upon, the service
architecture deployed on the POWER5 processor systems. The IBM service team has
enhanced the base service capabilities and continues to implement a strategy that
incorporates best-of-breed service characteristics from IBMs diverse System x, System i,
System p, and high-end System z™ offerings.
The goal of the IBM Serviceability Team is to design and provide the most efficient system
service environment that incorporates:
Easy access to service components
On demand service education
An automated guided repair strategy that uses common service interfaces for a converged
service approach across multiple IBM server platforms
By delivering on these goals, POWER6 processor systems enable faster and more accurate
repair while reducing the possibility of human error.
Client control of the service environment extends to firmware maintenance on all of the
POWER6 process-based systems. This strategy contributes to higher systems availability
with reduced maintenance costs.
This section provides an overview of the progressive steps of error detection, analysis,
reporting, and repairing found in all POWER6 process-based systems.
