Floppy Disk Drive (Option) - NEC Bull NovaScale R620 User Manual

Behaviour at Occurrence of Error
If POST or OS startup does not finish normally, the server will reboot itself automatically.
At the time of reboot, it will select the other CPU/IO module and run POST or OS startup.
In this manner, the server retries POST or OS startup with different combinations of CPU/IO modules. If POST does
not finish normally with any combinations, the server will stop with the state of DC OFF or Post end with an error
message displayed.
While performing retries, the server displays or registers the error types.
For details of error messages, see Chapter 7 "Troubleshooting."
POST Error Messages
When the server detects an error during POST, it will notify you of the occurrence in the following manners:
Displays an error message on the display unit.
Makes a beeping sound.
These notification methods are described in "POST Error Messages" in chapter 7.
IMPORTANT:
Before you contact your sales agent, write down the error messages and patterns of the beeping sound. They will
serve as helpful information at the time of maintenance.
CPU/IO Module Status
The CPU/IO module (#0 or #1) started first is managed as primary, and the module started later is managed as
secondary. If one CPU/IO module is disconnected because of the failure and others, the other module becomes primary.
The CPU/IO module to be started first is selected depending on the primary/secondary status of modules when the
server was shut down the last time.
The following devices are connected to the primary CPU/IO module by the hardware switch, although those can be
connected to both CPU/IO modules #0 and #1. When one CPU/IO module is disconnected because of a failure, those
are switched to the other module automatically and continue operating.
VGA
CD-ROM drive
USB device (keyboard, mouse, floppy disk drive)
IMPORTANT:
If the optional floppy disk drive is connected, the drive letter may change from A to B by switching
CPU/IO modules.
The drive letter of the CD-ROM drive is allocated again automatically when CPU/IO modules are switched.
The letter which is not used is allocated to the drive in the order of D to Z. If you want to set the fixed drive
letter to the CD-ROM, specify the drive letter which is not allocated in the order of D to Z after setting the hard
disk drive letter.
