Please replace the faulty drive with a new one of the same type and capacity.
NOTICE
Hot swapping
In devices with removable rack, you can replace the drive without turning off the device.
Replacement in devices without a removable rack may only take place when the device is
turned off.
The new hard disk can be integrated into the RAID system at operating system level with
the RAID software. This is not possible at BIOS level.
Points to note if the hard disk is replaced when the computer is turned off
Only a hard disk that was active and functioning correctly when you booted can later be
included in the RAID system.
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.
