That being said, the server appears to be fine (I'm in the process of running diagnostics) and I see it listed on the RedHat HCL: https://hardware.redhat.com/show.cgi?id=228312 Is there anything else I can be checking? centos redhat hard-drive hp-proliant share|improve this question edited Jun 15 '12 at 18:06 Dmitri Chubarov 1,8811820 asked Jun 15 '12 at 17:44 Mike B 3,9661967112 2 A proliant probably has a raid controller. Is the raid array initialized? –Dmitri Chubarov Jun 15 '12 at 17:49 @DmitriChubarov It does indeed - HP P400 Smart Array RAID. Can you please clarify what you mean by initialize? –Mike B Jun 15 '12 at 17:52 1 Mike, When you set up a new server, on the first boot you enter the RAID BIOS and configure the array. –Dmitri Chubarov Jun 15 '12 at 17:53 3 See this array configuration guide –Dmitri Chubarov Jun 15 '12 at 17:57 @DmitriChubarov Perfect. I'll check it out.
