Configuration Software and Utilities 43
At this time the SCSI controller starts the synchronization process (copy of the master disk
contents on to the secundary disk). The LED of both disks blinks in green.
This operation is very slow when performed under EFI: around 1 hour per GB disk space.
If the system is powered down during the synchronization, when the system is powered on the
synchronization restarts at the point it was interrupted.
Installation of the Operating System
The installation of an operating system on the disk may be conducted in parallel with the
synchronization of the disks.
Proceed as usual for the installation of a Windows or Linux operating system.
The installation of an operating system, and later its use, greatly increases the speed of the
synchronization process. When performed under OS running, the synchronization of 1 GB disk
space lasts around 8 minutes.
With the Linux operating system, after having installed it, it is necessary to install the
IMUtility.
This utility will allow correct operation of the HDDs LEDs and the hard drive fault LED on the
front panel (see Behavior hereafter).
This utility is available on the NovaScale 4020 Resource CD or at the Bull supports Web site.
After having installed the utility, it is necessary to reboot the system to make it operational.
Behavior
The LEDs on both disks and the hard drive fault LED on the front panel allow to ascertain the
current status of the RAID on the internal disks:
• In Normal operation (RAID function operational):
both LEDs on the 2 HDD drives blink simultaneously in green when I/O operations are
performed
Hard drive fault LED on the front panel is off
• When one disk is in failure:
The LED on the HDD drive in failure blinks in Amber;
the LED on the active HDD drive blinks in green when I/O operations are performed
The hard drive fault LED on the front panel is on (amber)
It is necessary to replace the disk in failure
• When one disk is missing:
The LED on the remaining HDD drive blinks in green when I/O operations are
performed
The hard drive fault LED on the front panel is off
If a new disk in inserted, the synchronization process immediately starts (see hereunder).
