The functioning hard drive is indicated in BIOS by its port number, or by the RAID software
by its port number:
Figure 7-4 Information about the functioning hard drive
Always replace the defective drive with a new one of the same type and capacity.
To be able to boot from the RAID system, you must place this first in the list of bootable
sources in the BIOS "Boot" setup menu. Otherwise the system will boot from the hard disk
you have just installed and the message "Operating system not found" will be displayed.
Note
BIOS messages during startup
At the first restart / cold start following a hard disk failure or installation of a new hard disk
(servicing), the RAID BIOS reports that the RAID functionality is no longer available and
offers the appropriate operator options.
Note
The new HDD can be integrated into the RAID system at operating system level by means of
the RAID software. Synchronization may take several hours, depending on system load.
