Replacing a disk on a RAID controller, with an already installed system?

Question

RAID

Good time!
A working machine with win10 OS The
Asus P8H61-V motherboard has a
St-Lab A-341
controller there are three identical 500Gb
disks WDC WD1003FBYZ-010FB0 (WD-WCAW36KS5D8N)
WDC WD1003FBYZ-010FB0 (WD-WCAW36RKNHT7)
two of which are in the system and merged into RAID1,
one of the disks was screwed up and the task was to replace one disk.
Hence the question, how to do it right?
Naturally, without reinstalling the OS!
Previously, I had nothing to do with RAID, I read their difference and capabilities, but I could not find information specifically on my hardware.
in the BIOS , that is, in UEFI, oh well, that's not the point, in general, there
is no raid selection in the drop-down menu as on the screen.
In Windows, the board driver is installed, and in the BIOS I can press F4 and get into the RAID settings menu, but what should I do next so as not to screw up the disk with Windows and info? How to properly mount a second disk in a RAID array?

Answer 1

They threw out the dead disk, put a new one. We went into the administration of the array and made a rebuild. Normal controllers have no problem with this. What your hardware can do - xs ... On Intel chips and many LSIs (with which I worked), the system detects a new screw at startup and offers a rebuild

Answer 2

What you see in the BIOS is a bit different, it's the chipset fake raid configuration.
Under raid you have a separate controller, judging by the description. This is the same fake raid, while also sata2.
As mentioned above, you can pull the drive right on the go and push a new one.
Rebuild in govnosoftoreida usually starts automatically.
Well, for good, this piece of textolite can be thrown away, you have free ports on the motherboard, also sata2.
