Predictive failure and dynamic component deallocation
Servers with POWER processors have long had the capability to perform predictive
failure analysis on certain critical components such as processors and memory.
When these components exhibit certain symptoms that may indicate a failure is
imminent, the system can dynamically deallocate and call home, when enabled,
about the failing part before the error is propagated system-wide. In many cases,
the system will first attempt to reallocate resources in such a way that will avoid
unplanned outages. In the event that insufficient resources exist to maintain full
system availability, these servers will attempt to maintain partition availability by
user-defined priority.
Uncorrectable error recovery
When the auto-restart option is enabled, the system can automatically restart
following an unrecoverable software error, hardware failure, or environmentally
induced (ac power) failure.
Serviceability
The purpose of serviceability is to repair the system while attempting to minimize
or eliminate service cost (within budget objectives), while maintaining high
customer satisfaction. Serviceability includes system installation, MES (system
upgrades/downgrades), and system maintenance/repair. Depending upon the
system and warranty contract, service may be performed by the customer, an IBM
representative, or an authorized warranty service provider.
The serviceability features delivered in this system provide a highly efficient service
environment by incorporating the following attributes
• Design for Customer Set Up (CSU), Customer Installed Features (CIF), and
Customer Replaceable Units (CRU)
• Error detection and Fault Isolation (ED/FI)
• First Failure Data Capture (FFDC)
• Converged service approach across multiple IBM server platforms
Service environments
The HMC is a dedicated server that provides functions for configuring and managing
servers for either partitioned or full-system partition using a GUI or command-line
interface (CLI). An HMC attached to the system allows support personnel (with
client authorization) to remotely log in to review error logs and perform remote
maintenance if required.
The POWER7 processor-based platforms support two main service environments:
• Attachment to one or more HMCs is a supported option by the system. This is the
default configuration for servers supporting logical partitions with dedicated or
virtual I/O. In this case, all servers have at least one logical partition.
• No HMC. There are two service strategies for non-HMC systems
– Full system partition: A single partition owns all the server resources and only
one operating system may be installed.
– Partitioned system: In this configuration, the system can have more than
one partition and can be running more than one operating system. In this
environment, partitions are managed by the Integrated Virtualization Manager
(IVM), which provides some of the functions provided by the HMC.
Service Interface
The Service Interface allows support personnel to communicate with the service
support applications in a server using a console, interface, or terminal. Delivering
