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.
