7-14 Troubleshooting
Fail to start the OS:
Is a Flash FDD connected to the server?
→
Take out the Flash FDD and restart the server.
Is the NEC EXPRESSBUILDER DVD (or the other bootable DVD/CD-ROM) in
the optical disk drive?
→
Take out the DVD (or the other bootable DVD/CD-ROM) and restart the server.
Is the OS damaged?
→
Use the recovery process of the OS to attempt to recover the damaged OS.
OS behavior is unstable:
Aren’t you making access to directory or file in /dev, /proc or /sys?
→
The NEC Express5800/ft series frequently saves and updates information related
to system operation and management in the following directories. Because
accessing any of these directories by a command or other means may impact fault
tolerant functions and make behavior of the system unstable, do not access them.
/dev/mem
/proc/kcore
/proc/bus
/proc/ft
/proc/ide
/sys
The server is not found on the network:
Is the LAN cable connected?
→
Make sure to connect the LAN cable to the network port on the rear of the server.
Also make sure to use the LAN cable that conforms to the network interface
standard.
Have the protocol and service already configured?
→
Install the distinctive network driver for the server. Make sure that the protocol, such
as TCP/IP, and services are properly specified.
