On checking the hard disk, no data is written into the disk.
Starting and Ending the System Diagnostics
There are two ways to diagnose the server: using the local console (keyboard) of the server itself, and using the
management PC via serial port (remote console).
IMPORTANT:
Two methods (LAN and serial port) are mentioned in the Chapter 6
"EXPRESSBUILDER" as the way of communicating in remote console. Use the serial port
to run System Diagnostics with remote console. The LAN connection is not for System
Diagnostics.
Start the diagnostics program as follows:
1.
Shutdown the operating system, and turn off the server. Then, unplug the power cord.
2.
Disconnect all the LAN cables from the server.
3.
Plug the power cord and turn on the server.
4.
Use the EXPRESSBUILDER CD-ROM to reboot the server.
See Chapter 6 "EXPRESSBUILDER" for details.
