When OS is in Operation

[?] The server is not found on the network:

Is the cable connected properly?
→ Securely connect the proper cable to the network port on the rear of the server. Additionally, make
sure that the cable conforms to the network interface standards.

Are BIOS settings correct?
→ You can disable the internal network controller using the BIOS setup utility. Check the settings with
BIOS setup utility.

Have you completed protocol and services settings?
→ Verity that the network driver for the server network controller has been installed. Also verify that
protocol such as TCP/IP or various services have been properly specified.

Is the transfer speed correct?
→ You can change the transfer speed or configure the setting for built-in LAN controller from VI client.
However, do not use the "Auto Detect" function. Fix the setting of the transfer rate to the same with
that of the connected hub. Also, check if the duplex mode is the same with that of the connected hub.
[?] Power-saving feature does not work:
→ The server does not support power-saving feature specified in [Power Option].
[?] A CPU/IO module cannot be integrated:
→ When a componet fails and is reintegrated, the following message may be recorded to the system
event log and the process is stopped. Such event indicates that the component's MTBF is below the
threshold and it is judged that repair is necessary. Thus the reintegration process cannot be
completed. Generally replacement of the component will be required, so contact your sales
representative. If reintegraating the component without repair is required for some reason, consult
your sales agent. It is possible to perform reintegration forcefully.
kernel: EVLOG: ERROR - x is now STATE_BROKEN / REASON_BELOW_MTBF
(x is a device number)
[?] Screen under changing (distorted display) can be seen when screen resolution is changed:
→ If screen resolution is changed while the entire system is under high load, screen under changing
(distorted display) may be seen.
This is because screen update is taking time to complete due to high load in the system. This is not
because an error is occuring. The screen will return to normal if you wait awhile.
[?] Screen does not appear after changing screen size:
→ The screen may not appear if failover occurs on the system when screen size is changed.
[?] Logs which are output in an environment where a Fibre Channel board (N8803-038) was installed:
→ The log below is periodically output in /var/log/vmkernel in an environment where a Fibre Channel
board was installed. However, there is no problem.
