Shalom,

If you have a raid card, by far the best way to do this is to use the hardware based raid utility, set this up and present it to the RHEL system prior to doing the OS install.

RHEL software raid configuration:

Raid 0 software raid configuration with lvm2.

Hi,

"RHEL server" isn't exactly a good description of the hardware that you've got...

Exactly what hardware have you got and what controllers are the hard drives connected to ?

As you've posted on a HP forum we could assume that you're using a ProLiant with a SmartArray controller, and that you'd need to use something like HP's Array Configuration Utility to set things up... but I don't like assuming !

Cheers,

Rob
