Displaying a defective hard disk of a RAID system in the RAID software
Note
Always replace the defective hard disk with a new hard disk of the same type and capacity.
In order to return to the safe RAID state after an error, the faulty hard disk must be replaced
by a new hard disk.
The RAID software indicates the following:
● A defective hard disk
● Details of the functioning hard disk:
The functioning hard disk is indicated by BIOS with its port number or by the RAID
software with its device port number.
The following figure shows the corresponding window in the RAID software with a RAID1
system.
You can find information on how to detect and replace a defective hard disk in the RAID
system in the section "Replacing a defective hard disk drive in the RAID system (Page 70)".
5.3.1.5
Special feature: Replacing hard disk in the RAID system when switched off
The RAID system does not automatically boot up when restarted if a defective hard disk was
replaced while the RAID system is switched off. Therefore, place the RAID system in the first
place of the bootable sources in the BIOS setup menu "Boot". Otherwise, the system will
boot from the hard disk you have just installed and the message "Operating system not
found" will be displayed.
