Checking The Server And System Configuration; Checking The Hardware Configuration And Fru Status - Fujitsu SPARC Enterprise M8000 Service Manual

2.5 Checking the Server and System
Configuration
Before and after maintenance work, the state and configuration of the server and components
should be checked and the information saved. For recovery from a problem, conditions
related to the problem and the repair status must be checked. The operating conditions must
remain the same before and after maintenance.
A functioning server without any problems should not display any error conditions. For
example:
The syslog file should not display error messages.
■
* mark is not displayed in XSCF shell command showhardconf
■
The administrative console should not display error messages.
■
The server processor logs should not display any error messages.
■
The Oracle Solaris Operating System (Oracle Solaris OS) message files should not
■
indicate any additional errors.

Checking the Hardware Configuration and FRU Status

To replace a faulty component and perform the maintenance on the server, it is important to
check and understand the hardware configuration of the server and the state of each hardware
component.
The hardware configuration refers to information that indicates to what layer a component
belongs in the hardware configuration.
The status of each hardware component refers to information on the condition of the standard
or optional component in the server: temperature, power supply voltage, CPU operating
conditions, and other times.
The hardware configuration and the status of each hardware component can be checked from
the maintenance terminal using XSCF Shell commands.
