possibility to configure RAID after installing system

[DESPOULAINS]

hello

after an initial installation of a server HP, I forgot to configure the RAID (other manufacturers implements basic). Is it possible to configure while the OS and applications are already installed?
if so, how? thank you

We need you to provide more details. What server model? Proliant? Integrity? Do you mean hardware RAID? What disk controller does the server have?

Hi, if you have installed the OS with hardware RAID disabled, if you enable it now, the OS will not boot, as the controller will be different.
In ML110 G4 there was the possibility of manually loading the driver in Windows before enabling hardware RAID:

Go to Control Panel-> Add New Hardware->Device is connected->New Hardware->Raid Controller->Have Disk->Browse to the folder where the Embedded SATA RAID Drivers were extracted. Select the .inf file->Install Adaptec Raid Driver .

Restart the Server go to BIOS enable the Embedded SATA RAID .

Press F8 and go to Sata Raid BIOS->Configure the Drives->Create Array->Raid 0/1 A warning message will appear "Warning: Configuring the drives will erase all Array information from the selected drives, if that drive is part of an array. Arrays using any of these drives as members will be affected! Do you want to continue?(Yes/No): ". Press "Y " to continue.

If Raid 1 is selected it will ask you what is the Source Disk, select the Right Disk in which OS was installed previously. Warning message might appear again. Select "Y ".

Rebuild will take sometime, once rebuild is complete restart the server.
