Detailed Product Descriptions 57
enables IBM service representatives to bring along needed replacement
hardware components during a service, thus minimize system repair time.
3.1.2.3 Environment Monitoring Functions
Following is a list of the provided environment monitoring functions.
• Fan speed monitoring to provide warning and orderly system shutdown
when the speed is out of operational specification.
• AC power loss sensing to provide orderly system shutdown.
3.1.2.4 Error Handling and Reporting
In an unlikely event of system hardware or environmental induced failure, the
system Run-Time Error Capture capability will systematically analyze the
hardware error signature to determine the cause(s) 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 automatically reported to AIX operating system. The Error Log Analysis
(ELA) can be used to display the failure cause and the physical location of
failure hardware.
3.1.2.5 Availability Enhancement Functions
On-line (concurrent) Diagnostics with Error Log Analysis and Service Aids
allow administrators or IBM service representatives to diagnose potential
system malfunction without interrupting end-user operation.
The auto-restart (reboot) option, when enabled, automatically reboots the
system following an unrecoverable software error or hardware failure.
3.1.2.6 Serviceability
The Model 150 is designed for customer setup of the machine and for
subsequent addition of most features (adapters/devices). The Model 150
supports personnel to remotely log into a system to review error logs and
perform remote maintenance.
The diagnostics consists 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
mode (service mode), run in maintenance mode, or run concurrently
(concurrent mode) with other applications. They have access to the AIX Error
Log and the AIX configuration data.
Service Mode allows checking of system devices and features.
