PERC 5/i remove disks from RAID

[Rafael Diaz Maurin]

Hi everybody,

I have a Power Edge 1950 with a Perc 5/i controler with 3 SAS disks.

For some reasons, I wan't to remove those disks from the RAID5 in order 
to have 3 separate Hard Disks in my Operating System.

I can't succeed in it with the Perc BIOS, nor the OMSA v5.
Is it possible to do this with Open Manage or MegaCLi ?
And how can I do it ?

Thank you for your answers,
