• AC power loss sensing to provide an orderly system shutdown
3.2.3.6 Error Handling and Reporting
In the unlikely event of system hardware or environmentally induced failure,
the system Run-Time Error Capture capability systematically analyzes the
hardware error signature to determine the cause of failure. The analysis
result will be stored in system Non-Volatile RAM (NVRAM). When the system
can be successfully rebooted either manually or automatically, the error will
be reported to the AIX operating system. The Error Log Analysis (ELA) can
be used to display the failure cause and the physical location of failing
hardware.
With the integrated service processor, the system has the ability to
automatically send out an alert through the phone line to a pager, or call for
service in the event of critical system failure.
Environmental and Power Warnings (EPOW) is an option that is implemented
in the Model 260. This option provides environmental conditions of the
system to the user in order to try and minimize damage to the system if limits
are close to being exceeded. This option also indicates failure conditions to
AIX for appropriate action.
3.2.3.7 Availability Enhancement Functions
The following enhancements provide additional system availability function.
• On-line (Concurrent) Diagnostics with Error Log Analysis and Service Aids
that allow administrators or IBM service representatives to diagnose
potential system malfunction without interrupting end-user operation
• Auto-restart (reboot) option, when enabled, to automatically reboot the
system following an unrecoverable software error, software hang,
hardware failure, or environmental-induced (AC power) failure
3.2.3.8 Serviceability
The Model 260 is designed for Customer setup of the machine and for
subsequent addition of most features (adapters/devices). For a fee, IBM
Service can perform the installation.
The Model 260 allows support personnel to remotely log into a system to
review error logs and perform remote maintenance. The Model 260 Service
Processor enables the analysis of a system that will not boot.
The diagnostics consist of Stand-alone Diagnostics (system dedicated to
service) and On-line Diagnostics. On-line Diagnostics, when installed, are
resident with AIX on the disk or system. They can be booted in single user
