[CentOS] HP Proliant ML150 : how do I access disks ?

[Joseph L. Casale]

>Last week I bought some server hardware, a used HP Proliant ML150.

That server comes with an onboard sata raid controller that needs a dd
that HP only supports with an rhel kernel <= 5.3.

If you have a Smart Array controller the driver is built in.

If you don't, forget about the sata raid, setup the controller as non raid
in the bios, and use md.
