Perc 5/i Hotswappable in Linux

Hi everybody, hope y'all going well. I'm having a little issue using my Poweredge 2950. First I also own a Poweredge 1950 which runs on Oracle Linux. With this one, if I add or remove an hotswap drive (except the OS drive) the OS disk utility see it and automatically make it readable. But with the 2950 (who works with Perc 5/i), to add drive I always need to reboot the machine and enter the raid utility to set the physical disk as a virtual, and the os will see it.

The 2950 will run with CentOS and with will be use as data storage to I absolutely need to have them Hotswappable via the OS.

I tried updating the firmware but it does nothing, I know i'm not a professionnal using server but this is disturbing

Thank you for your suggestion
