I think there was just a thread 'bout this, and I didn't pay attention... and then I walked into our smallest server room to rebuild a server with CentOS... and that's what it is. The problem I'm having is this: there are two 1T SAS drives, raided, via the controller. There's also a 750G SATA drive. The Dell test suite sees it, and reports that SMART says it's fine. However, no matter what I do, the BIOS doesn't see it, and when I boot to linux text, fdisk only sees the raided 1t.
Clues for the poor? I want to put the system on the SATA drive, leaving the raid for data.

I have no idea what R605 is, but you need to state the version of Centos (imagine that) and the type of disk controller, i.e., post
lspci
It's possible the problem is a BIOS setting, e.g., you may need to turn on AHCI.
R605 is a power edge server model I think.The Perc6/i is a Dell rebranded raid controller, it's actually an LSI in disguise. Try downloading the Megaraid utilities from LSI and using them to see the status of the card.
Also, when you boot the R605, you should be able to get into the Perc's firmware for drive creation/maintenance. You might want to check there to see how it thinks things are configured and it hasn't decided the 750G drive is a hotspare or something (a hotspare wouldn't show up to the OS).
I'm assuming all the drives are connected to the Perc6/i controller. Drives connected to the Perc controller won't necessarily show up to the BIOS.

Hmmm, I think I see the Linux/CentOS megaraid load as it comes up to the install screen (before I get to look at partitioning).

As far as I can tell, it doesn't think it's a hot spare. Using the firmware configuration utility, it sees the physical drive, and that's it.

Yeah - five (I think) hot swap drive bays in the front of the box, all on an SAS backplane.

you need to export drive as jbod or raid0 if you want to use it on os. this is typical on hardware raid controllers.

this sounds like the right solution, you can do this either form the firmware or the megaraid command line tool MegaCli64 (MegaCli for non-64 bit systems)

Thanks, everyone. Making the single drive a RAID-0 was the answer. From the boot, it was <ctrl-R>, and then follow what y'all were saying. As soon as I did that, and had the controller software make it bootable, when I got out and went into the CenOS install, everything was wonderful - I even saw what had been on there (before I blew it all away).
Thanks again.

--- See the drive in the raid configurator? ^C-M
Configure the 750G drive as a Raid 0? Init the Scrubing?
The controler otherwise does not know the drive exists (allthough it does).
Otherwise seek help @ linux-poweredge@dell.com list is searchable via google.
