Troubleshooting the System

Your server provides several methods for detecting problems in the system:
!
LED status indicators on hardware components, such as boards and drives
!
Error messages, logs, and status displayed on a monitor from the integrated iSP
Service Processor.
Hardware diagnostics from LED status requires accessing boards integrated in the
server. Hardware diagnostics should be done by trained NEC Support personnel.
Record any error messages displayed on the console and provide the information to the
NEC Support technician.
The service processor provides the following functions for system status and
diagnostics:
!
Virtual SOP – displays the system operating state for each partition with periodic
updates. It displays partition configuration information and failure information (see
"Virtual SOP" in Chapter 3.
!
OS Console – redirects the serial input/output for the operating system (including
BIOS).
!
SP Command Console – allows you to monitor service processor output messages
required for system operation and maintenance and to enter commands for the
service processor. The SP Command Console lets you run commands required for
system operation.
From the iSP Main Menu, you can switch the SP Command Console from normal
operation to maintenance mode by entering the change command mode "CM"
command at the iSP prompt.
Some of the commands you can use for troubleshooting include:
!
HC command to display and/or modify hardware configuration, including partitions.
!
DL to display the logs stored in iSP.
!
DT to display the SP RTC and to set it.
!
EN to display environmental information such as power state and temperature status.
See Chapter 3, "Service Processor" for detailed information for using the iSP service
processor functions.
