RAID 1 Synchronisation to be done at HP Server
-
Sounds like all is well now.
-
@scottalanmiller Yes everything Went Good and configured and Rebuided the OS
-
So is this hardware or software RAID?
Also, There is no way to add the replacement drive to the system while the system is live?

It's software RAID.

10)Then,disconnect any one of the hard disk from the RAID and after that add new hard disk which should be unallocated.Then,connect the new hard disk in the port in which you have disconnected the hard disk(RAID)ie)In my situation I have A and B hard disk and disconnected A harddisk and I connected the new hard disk to which I have already connected A hard disk.(SATA cable to be connected).
11)Then,press F8 button to go configure RAID rebuild process.This F8 button should be pressed when the system shows RAID device details in the monitor.
12)Then,go to the First option which will open the Main menu in that go to the Add/Delete Hotspare menu.After that add the new hard disk which to be added in the RAID.
13)Then,go to the Manage Array menu and after that select the RAID device and then Click Ctrl+R key to rebuild the RAID Array with the new hard disk.
14)Then the rebuilding of the data will be carried out more than 2 Hours according to the data present in the OS.After that boot the server and find that the RAID is rebuild by going to the OS without any errors.Am I misunderstanding that he's making these changes in the BIOS/before the OS loads? Pressing F8 happens when?
This is the part about Fake RAID I've never understood - you have to do something special in the BIOS, but at the same time you have to have a special driver loaded in Windows.

Yes, it's Fake RAID.

That's the "fake" bit. Just enough hardware to have something appear outside the OS, while all of the RAID itself is on software running on the OS. There is no hardware RAID, but there is hardware. But no more hardware than any SATA controller would have. ANY PCI card can present itself during POST and give you a menu. Your NICs do this all the time.

Why does the hardware need to be involved at all?

To make it appear like people are buying hardware RAID. The whole purpose is to trick people into buying something worthless and making it seem good.

Some Video Cards too. Thankfully the BIOS on my computer (an HP Z800) lets me disable or enable option roms per port as even though I have an SSD all my cards slow boot times down - a lot.

Yup video cards can do that. OOB Management cards do this too (ILO, Drac, etc.)
