NEC Express5800 Series User Manual

Troubleshooting 7-27
Fail to access to the CD-ROM:
 Is the CD-ROM properly set in the CD-ROM drive tray?
o The tray is provided with a holder to secure the CD-ROM. Make sure that the
CD-ROM is placed properly in the holder.
 Is the CD-ROM applicable to the server?
o The CD-ROM for Macintosh is not available for use.
 Is the media mounted?
o If a failover occurs while the media is mounted, the media is forcibly unmounted.
Therefore you need to mount it again. (When mounting CPU/IO module and at a
failover, errors such as buffer I/O error may be recorded, but there is no problem
on operation as they are specifications of the server.) After the failover, device
name of the CD-ROM drive may be changed (Ex. from scd0 to scd1), that
phenomenon is due to the specifications of the server and does not affect the
operation. In such a case, specify the changed device name for mounting the
media.
Fail to access the hard disk:
 Is the hard disk applicable to the server?
o Operation of any device that is not authorized by NEC is not guaranteed.
 Is the hard disk properly installed?
o Make sure to lock the hard disk with the lever on its handle. The hard disk is not
connected to the internal connector when it is not completely installed (see
Chapter 8). When the hard disk is properly installed, the drive power LED for the
hard disk is lit while the server is powered.
Fail to start the OS:
 Is a floppy disk in the floppy disk drive?
o Take out the floppy disk and restart the server.
 Is the NEC EXPRESSBUILDER CD-ROM (or the other bootable CD-ROM) in the
CD-ROM drive?
o Take out the CD-ROM and restart the server.
 Is the OS damaged?
o Use the recovery process of the OS to attempt to recover the damaged OS.
 Is reset performed by the boot monitoring function?
o For the following cases, boot monitoring function needs to be disabled for NEC
Express5800/ft series. To disable it, see “Step 3: Disable the Startup Monitoring
Function Setting.”
- To enter into the kudzu setup mode and make settings while the OS is
starting.
- To change the boot mode to the interactive startup mode.
