Hi, Up until now, I've only installed Linux either on "desktop" hardware, meaning one of the desktop PCs in the LAN acted as a server machine for the network, or I rented some dedicated server somewhere in a datacenter. Last week I bought some server hardware, a used HP Proliant ML150. It's the first time I am dealing with this sort of hardware. The hardware was sold "as is", without any warranty. When I open the front cache, there are six small "drawers", and the bottom two of them each contain a 72 GB hard disk. I inserted a CentOS 5.4 install CD (1 of 6), and the installer (linux text) booted correctly. But when it comes to partitioning, it "sees" no disk. Unlike the usual desktop hardware, there seems to be a myriad of configuration options, and I'm a bit lost here. So first things first. How do I configure this machine so the CentOS installer can actually recognize my two inserted hard disks as such : say, sda and sdb or similarly ? Any suggestions ? Niki Kovacs
