Type:

Warning

Event ID:

1506

Description:

The doubleness information about an I/O device is not reported.

Video mode cannot be changed by using the Xrandr feature of XServer:

οSpecification of the server. For setting the video mode, see “SETTING THE VIDEO MODE” on page 3-10.

Settings such as screen size and color are made from Control Panel, but they are not enabled:

οSpecification of the server. Even if you change the video mode on the [DisplaySetting] tab displayed by selecting the Start menu, [System], [Control Panel], and then [Display] or by right-clicking the blank space of the desktop and selecting [Video Property], the change is not reflected to the system. For setting the video mode, see “SETTING THE VIDEO MODE” on page 3-10.

DISK ACCESS LED is amber and blinking:

†Is the mirror of the hard disk not removed?

οCheck [Disk Management], and reconfigure the mirror if the mirror is broken.

(See “HARD DISK CONFIGURATIONS THAT CAN BE BUILT ON THE NEC Express5800/ft series” in Chapter 3 “Linux Setup and Operation.”)

Relevant Disk LED and DISK ACCESS LED illuminate amber during the process of automatic mirror reconfiguration. During the process of reconfiguration, DISK ACCESS occurs at the same time, and amber and green appear to illuminate alternately. Wait for a while if it is found out that the mirror is being reconfigured in “Disk Management,” etc.

When one of the disks that configure the mirror is broken, the other disk becomes “Failed Redundancy.” In this case, DISK LED also illuminates amber. Replace the failed disk and reconfigure the mirror.

The setting screen for kudzu is displayed at each startup:

οWhen the system is started from a module different from the previous startup, the setting screen for kudzu is displayed. However, no operation is required.

The screen of X is not displayed after failover:

οThis phenomenon may occur when you start X by running startx on the text console. For using X, read the notes on page 3-11.
